AbstractIn southeast Rhum, a Mesozoic/Tertiary sequence is preserved as a fault-bounded and rotated wedge. This is juxtaposed between Precambrian rocks (Torridonian sediments and Lewisian gneiss) and caught up in the complex structure of the Tertiary Main Ring Fault (MRF), which shows three distinct phases of movement. The Mesozoic rocks comprise fossiliferous limestone, sandstone and shale, which show differing degrees of thermal metamorphism depending on their relationships to the Layered Complex. On the basis of faunal and lithological evidence the Mesozoic sediments have been correlated with the Lower Liassic Broadford Beds. The Rhum sediments are overlain by sheared Tertiary basalts, the contact between them probably representing the original landscape unconformity. The presence of these younger strata caught up along the MRF provides crucial evidence for a major phase of central subsidence in the early history of the Rhum Tertiary volcanic centre.

Abstract The Vienna Basin is situated at the contact of the Bohemian Massif, Western Carpathians, and Eastern Alps. Deep borehole data and an existing magnetotelluric profile were used in density modelling of the pre-Neogene basement in the Slovak part of the Vienna Basin. Density modelling was carried out along a profile oriented in a NW–SE direction, across the expected contacts of the main geological structures. From bottom to top, four structural floors have been defined. Bohemian Massif crystalline basement with the autochthonous Mesozoic sedimentary cover sequence. The accretionary sedimentary wedge of the Flysch Belt above the Bohemian Massif rocks sequences. The Mesozoic sediments considered to be part of the Carpathian Klippen Belt together with Mesozoic cover nappes of Alpine and Carpathian provenance are thrust over the Flysch Belt creating the third structural floor. The Neogene sediments form the highest structural floor overlying tectonic contacts of the Flysch sediments and Klippen Belt as well as the Klippen Belt and the Alpine/Carpathians nappe structures.

AbstractThe clay mineralogy of a set of Tertiary marine sediments from the Internal Subbetic of the Betic External Zone was examined. Two types of sedimentary environment were distinguished: a platform environment consisting of limestones, marls, organogenic limestones, conglomerates and silexites distributed heterogeneously in time and space; and deep environments, where the sedimentation consisted of marls, marly limestones, marly clays and silexites, with no sedimentary gap. A third group of sediments studied belongs to the Águila Complex, with mineralogical and stratigraphic characteristics very similar to the platform sediments. This third type of sediment is found in the sediments of the Campo de Gibraltar Complex as large, disperse blocks resulting from tectonic activity. A very similar mineral association was observed in all three domains, consisting of smectite, illite, mixed-layer I-S, kaolinite and lesser amounts of palygorskite and chlorite. Materials mainly derive from the erosion of Mesozoic sediments, and sedimentation was controlled by the compressive tectonics of the region.

Probable marsupial footprints, exhibiting syndactyly of digits II and III of the pes, are described and placed into a new ichnogenus and species, Duquettichnus kooli. The type specimen is from the Cretaceous (late Aptian to early Albian) sediments of the Peace River canyon near Hudson Hope, British Columbia. This constitutes the first evidence for syndactyly among Mesozoic mammals, whose postcranial skeletons are very poorly known. It may well also constitute the earliest evidence for the presence of marsupials in Mesozoic North America.

Introduction. Acritarchs are one of the orthostratigraphic groups of microfossils that are widely used in Proterozoic and Paleozoic biostratigraphy. In the Mesozoic period there is a decrease in this group, and this is due to certain reasons. Formulation of the problem. Acritarchs are studied by palynologists from samples of Mesozoic sediments in combination with other representatives of organic bone microplankton, primarily with dinocysts. In the practice of Ukrainian micropaleontologists, the role of such a group as acritarchs, which may be unique in paleoecological reconstructions of the environment, is underestimated. History of the study of acritarchs. None of the researchers studied the group of acritarchs in the Mesozoic deposits of Ukraine. In scientific works it was noted only about the presence of these forms in the description of palynological complexes of Jurassic, Cretaceous and other times. Brief description of the group. Acritarchs are unicellular, non-colonial, organic microfossils. Formulation of the purpose of the article. The aim of the study was to focus on such a little-studied group for the Mesozoic as acritars and to prove its role and significance for stratigraphic and paleoecological constructions. Materials and methods. The research material was samples of rocks of the Middle, Upper Jurassic and Cretaceous deposits, selected separately from 93 sections, but from all major tectonic structures of Ukraine: Peninsky zone of the Carpathians, Volyn-Podolsk plate, western and eastern slopes of the Ukrainian Shield, Priazovsky array of the Ukrainian shield, Dnieper-Donetsk basin, Donbas, South Ukrainian monocline (Black Sea basin), Crimea, North-Azov depression and Azov shaft (Ukrainian part of the Sea of Azov). Presentation of the main material of the study. Acritarchs Jurassic and Cretaceous belong to 10 genera, including 11 species. The most common species found in both Jurassic and Cretaceous sediments of Ukraine are acritarchs Micrhystridium fragile and Fromea sp. Jurassic complexes are slightly richer than chalk in terms of percentage and are represented mainly by Micrhystridium spp., Micrhystridium flagile, M. longum, Veryhachium brevitrispinum, Wilsonastrum sp., Baltisphaeridium sp. Cretaceous: Micrhystridium spp., Micrhystridium fragile, M. longum, Baltisphaeridium breviciliatum, B. aff. capillatum, B. annelieae, B. accinctum, Acanthodiacrodium sp., Solisphaeridium inaffectum, Comasphaeridium sp., Comasphaeridium aff. brachyspinosum, Veryhachium spp., Veryhachium singulare, Leiofusa stoumonensis, Fromea sp., Ascostomocystis sp. The article presents photo tables of images of Jurassic and Cretaceous acritarchs. Conclusions. For the first time in Ukraine, acritarchs were found in samples from Jurassic and Cretaceous sediments and attention was focused on such a little-studied group for the Mesozoic. Their certain role and significance for stratigraphic and paleoecological constructions are proved, their species composition and vertical distribution in sections of Mesozoic sediments are studied. The regularities of the distribution of acritarchs in the same age layers are established. Analyzing the Jurassic and Cretaceous microfossils studied from Mesozoic sediments from 93 sections of different regions of Ukraine, we can say that the trend of disappearance of acritarchs during the Mesozoic is weakly observed. Jurassic forms of acritarchs are up to 5% in the complex, Cretaceous - up to 4%. The next stage of work should be the study of acritarch Jurassic and Cretaceous deposits of all regions of Ukraine for the purposes of the overall picture of the reproduction of paleoecological conditions in Ukraine during the Jurassic and Cretaceous period.

Mesozoic sediments are the main objective for hydrocarbon exploration in the eastern part of Akimeugah Basin, Papua. However, little information is currently available on paleogeography and subsurface distribution of the Mesozoic rock unit. This study analyzed Mesozoic rock unit from outcrops at Wamena and surrounding area to wells data in the eastern part of Akimeugah Basin, Papua. Outcrop and well correlation was made to interpret paleogeography of Mesozoic unit. This study was using existin 2D seismic and passive seismic tomography data to determine the distribution of Mesozoic rock unit in the subsurface and its hydrocarbon potential. The Mesozoic rock unit in the eastern part of Akimeugah Basin is divided into four formations based on their lithological characteristic. Respectively from old to young, Kopai, Woniwogi, Piniya and Ekmai Formation. The depositional environment of Mesozoic rock unit in the southern part of the study area is shore/tidal to shelf and basin fl oor in the northern part. Three Mesozoic potential plays in the studied area are divided into 1) Central Range Mountains thrust-fold belt play, 2) Akimeugah low land thrust-fold belt play and 3) Tanah Merah pinch-out play. The results presented in this paper are expected to be a guide for further hydrocarbon exploration in the study area.

Terrestrial landscapes have existed in parts of southern South Australia since the Carboniferous to Permian Gondwanaland glaciation. Widespread weathered zones and ferricrete horizons and crusts on present highland surfaces in the region have been ascribed by various workers to Mesozoic or early Tertiary weathering phases. A critical examination of field relationships, however, points instead to complex reworking and continuous weathering of relic landscapes since early Mesozoic times, leading to the intricate patterns of sediments and soils forming the present regolith. Ferricrete crusts sporadically distributed on the highland surfaces are interpreted dominantly as remnants of iron-impregnated sediments of ancient valleys or depressions. The great but variable thickness of kaolinized bedrock beneath the highland surfaces, regarded by other workers as the mottled and pallid zones of a 'laterite' profile, is the integrated product of leaching and weathering throughout the Mesozoic and Cainozoic and cannot be assigned to separate and distinct climatic events. The use of weathered landsurfaces and ferricretes as morphostratigraphic markers in such landscapes is questionable.

AbstractThis paper shows how heavy minerals and single-grain varietal studies can be conducted on silt (representing c. 50% of world's sediments) sediments to obtain quantitative data as efficiently as for sand-sized sediments. The analytical workflows include heavy mineral separation using a wide grain-size window (15–355 μ) analysed through integrated optical analysis, Raman spectroscopy, QEMSCAN microscopy and U–Pb dating of detrital zircon. Upper Jurassic–Cretaceous silt-sized sediments from the Mandawa Basin of central-southern Tanzania have been selected for the scope of this research. Raman-aided heavy mineral analysis reveals garnet and apatite to be the most common minerals together with durable zircon, tourmaline and subordinate rutile. Accessory but diagnostic phases are titanite, staurolite, epidote and monazite. Etch pits on garnet and cockscomb features on staurolite document the significant effect of diagenesis on the pristine heavy mineral assemblage. Multivariate statistical analysis highlights a close association among durable minerals (zircon, tourmaline and rutile, ZTR) while garnet and apatite plot alone reflecting independence between the three groups of variables with garnet increasing in Jurassic samples. Raman data for garnet end-member analysis document different associations between Jurassic (richer in A, Bi and Bii types) and Cretaceous (dominant A, Ci and Cii types) samples. U–Pb dating of detrital zircon and their statistical integration with the above-mentioned datasets provide further insights into changes in provenance and/or drainage systems. Metamorphic rocks of the early and late Pan-African orogeny terranes of the Mozambique Belt and those of the Irumide Belt acted as main source of sediment during the Jurassic. Cretaceous sediments record a broadening of the drainage system reaching as far as the Usagran–Ubendian Belt and the Tanzanian Archean Craton.

The article presents an analysis of a large array of results of palynological studies of Mesozoic and Cenozoic sediments of Ukraine and adjacent regions of Belarus and Russia. Numerous literature data on the palynological characteristics of Meso-Cenozoic sediments and the materials of the authors are summarized according to the results of spore-pollen analysis of Mesozoic and Cenozoic sediments within the main tectonic structures of Ukraine. It has been established that the genus Pinus (Pinaceae) is an integral part of the Meso-Cenozoic flora of Ukraine. Although, the participation in the flora and vegetation of the genus Pinus and its species diversity in different periods of geological time were different. Despite the long history and significant achievements of palynological research of Meso-Cenozoic sediments of Ukraine, no attention has been paid to the historical aspect of Pinus development in the Meso-Cenozoic flora. This work is presented as the first stem to fill this gap. The genus Pinus has a large stratigraphic range, but its species diversity and quantitative changes in the composition of Mesozoic and Cenozoic flora of different ages are markedly different. The analysis of these changes made it possible to trace the emergence and main levels at which the species composition was renewed and the role of Pinus in flora increased during the Mesozoic and Cenozoic. According to the results of the research, 5 levels of increasing the participation of the genus Pinus and changes in its species affiliation in the Mesozoic flora were established: Aalenian period of the Middle Jurassic (appearance of the first representatives of Pinus); Oxfordian time of the Late Jurassic; Valanginian – Early Barremian times of the Early Cretaceous; Albian time of the Early Cretaceous; Late Campanian time of the Late Cretaceous. 5 levels of increasing the role of Pinus and its species diversity for the flora and vegetation of the Cenozoic were also established: Oligocene time of the Paleogene, Konkian-early Sarmatian time of the Middle Miocene; early Pontian (Ivankov) time of the Late Miocene; early Kimmerian time (early Sevastopol) of the Early Pliocene and Martonosha time of the Early Neopleistocene. Certain levels have been traced for the similar age of Cenozoic flora of Belarus and Russia.

This thesis represents the results of a study concerned with the various chemical and thermal processes which produce remagnetizations in continental sediments. Information has been gathered from a number of disciplines; palaeomagnetism, petrography, diagenesis, thermal history modelling. These techniques have been combined to produce a model of the processes by which sediments in particular areas of the United Kingdom have been remagnetized. In southwest Dyfed (South Wales), the Old Red Sandstone (Silurian to Devonian in age) has been remagnetized both chemically and thermally in the Late Carboniferous by fluids precipitated during the Variscan Orogeny. This can be concluded from the palaeomagnetic data which indicate that the remagnetization occurred approximately half-way through the Variscan folding event. In Anglesey (North Wales), the Old Red Sandstone (Lower Devonian) was folded by an earlier event, the Acadian Orogeny (Middle Devonian) and was not greatly affected by the Variscan event which was terminated over 100km to the south. However, the uplift associated with the Variscan event brought the Old Red Sandstone of Anglesey into the realm of oxidising fluids and chemically-precipitated haematite produced a remagnetization which is Permian in age. Fold tests clearly show that the remagnetization post-dates folding in this area. In the southern North Sea, the Barren Red Measures (Westphalian C, Carboniferous) contain chemically-precipitated haematite which was also produced as a result of Permian uplift in the wake of the Variscan Orogeny. However, the main remagnetization is associated with Triassic haematite precipitation produced by lateral flow of fluids along permeable channel sandstone units. The fact that some of the sandstones are remagnetized at this time whilst others are not is perhaps indicative of the interconnectivity of the sandbodies. In southwest Birmingham (Central England) the Keele Formation (Westphalian D, Carboniferous) provides an onshore analogue (in terms of age) to the southern North Sea samples. In this area there is a similar Permian age of remagnetization as that seen in Anglesey, produced as a result of uplift in the Variscan foreland. However, unlike Anglesey, these rocks also contain a primary magnetization which can be isolated from thermal demagnetization experiments. Present day weathering of the Keele Formation has imposed a weak magnetization (probably held within grains of goethite) on those rocks which lie within 10m of the surface, particularly in the more permeable sandstone units. The other effect of the present day weathering is that it tends to remove the finer grains of haematite which tend to be associated with Permian remagnetization. On the Isle of Arran (West Scotland) the New Red Sandstone (Permian and Triassic) has been remagnetized by a number of igneous intrusions which were produced as a result of Lower Tertiary hot spot activity beneath the British Isles. Palaeomagnetic experiments have been compared with computer models of heat flow around a small dyke to show that the remagnetization associated with the intrusions is a product of both thermal and chemical processes. The thermal processes are a product of direct heat flow from the intrusions which thermally remagnetizes pre-existing magnetic grains. However, the chemical processes are driven by convectional flow of fluids through the permeable Permian and Triassic sandstones to precipitate new magnetite and haematite grains. Despite the high level of thermal and chemical activity in this region in the Lower Tertiary, many of the rocks still retain a primary component of magnetization associated with deposition or early post-depositional processes. In summary, the pre-Permian sediments studied in this thesis appear to be particularly prone to remagnetization as a result of Variscan movements and the resulting uplift of southern Britain. On the Isle of Arran Permian and Triassic sediments which post-date the Variscan event are affected by a combined thermal and chemical remagnetization associated with Early Tertiary hot spot activity. The results of this thesis have shown the value of using palaeomagnetic techniques to time remagnetizations in continental sediments. In addition, the results have outlined a number of key geological events since the Devonian which are likely to be responsible for a number of the remagnetizations seen in the rocks of the United Kingdom. Therefore, these results can be used in a predictive manner for future palaeomagnetic studies in the rocks of this country and perhaps even further afield. For example, the effects of the Variscan Orogeny have produced remagnetizations in the rocks of Europe, Africa and north America. It is considered essential that all future work in this field should include the study of the burial history for the sedimentary basins covered as the remagnetizations explained in this work have all been intimately related to particular burial or uplift episodes. In addition, petrographic analysis helps to distinguish the textural phases of the magnetic grains which are responsible for the remagnetizations and are thus also essential elements in the study of remagnetizations in sedimentary basins.

The Taimyr Peninsula is a key element in the circum-Arctic region and represents the northern margin of the Siberian Craton. The Taimyr Peninsula preserves late Paleozoic through Mesozoic clasitic sedimentary successions in its Mesozoic fold belt, providing an ideal location to investigate the Mesozoic tectonic evolution associated with the opening of Amerasia Basin within a circum-Arctic framework. This thesis aims to establish the tectonic setting in which the late Paleozoic through Mesozoic sediments of Taimyr were deposited, in order to correlate Taimyr with other Arctic terranes utilizing provenance investigations. Multiple methods are adopted, including petrography, heavy mineral analysis and detrital zircon U-Pb geochronology.  The preliminary results of this work indicate that the late Paleozoic sediments of southern Taimyr were deposited in a foreland basin of the Uralian orogen during Uralian orogeny. The final collision between Baltica and Siberia in the last stage of Uralian orogenesis occurred between Early and Late Permian. Early Cretaceous sediments in northern Taimyr were mainly derived from Siberian Trap-related magmatism in Taimyr. Cretaceous sediment deposition is unrelated to Jurassic to Cretaceous rifting associated with the Verkhoyansk fold belt and instead relates to a rifting or post-rifting passive margin setting.

A região de Franca situa-se na borda nordeste da Bacia do Paraná, sendo margeada a nordeste por um soerguimento regional contemporâneo à individualização da Placa Sul-Americana e abertura do Oceano Atlântico Sul, o Soerguimento do Alto Paranaíba. A área é caracterizada por rochas do Grupo Araxá-Canastra (Pré-Cambriano) sobrepostas discordantemente por, da base para o topo, arenitos e conglomerados glaciogênicos da Formação Aquidauana (Permo-Carbonífero), arenitos eólicos e conglomerados eólico-fluviais da Formação Botucatu (Jurássico-Cretáceo) intercalados por rochas basálticas (derrames e sills) da Formação Serra Geral (Cretáceo), e rochas siliciclásticas do Grupo Bauru (Cretáceo Superior). Estas rochas encontram-se recobertas por sedimentos inconsolidados (Cenozóico), freqüentemente lateritizados. A história geológica mesozóico-cenozóica da região de Franca foi determinada por mecanismos tectono-sedimentares controlando a distribuição da sedimentação detrítica e formação de pláceres diamantíferos. O estudo de fácies sedimentares das unidades mesozóico-cenozóicas permitiu a caracterização das assembléias mineralógicas presentes, sob o enfoque de sedimentação fortemente vinculada a eventos de desnudação continental, com o preenchimento sedimentar de bacias, associado à elaboração de superfícies de aplanamento. O comportamento morfoestrutural e morfotectônico, ao qual as unidades aflorantes foram submetidas, condicionando a morfologia do relevo e a instalação da rede de drenagem num quadro estrutural, permitiu a caracterização da evolução tectono-sedimentar da região, sob um enfoque neotectônico. No Cenozóico, a morfologia do relevo e a instalação da rede de drenagem parecem fortemente controladas por um quadro de estruturas tectônicas...
The region of Franca is located in the northeastern limits of the Paraná Basin, aside the Alto Paranaíba Uplift, with associated kimbelitic bodies. Its evolution is contemporaneous to the individualization of the South America Plate and by the opening of South Atlantic Ocean. The Mesozoic-Cenozoic geology of the Franca region is characterized by basement rocks of Araxá Group (Pré-Cambrian) overlaid, from bottom to top, by glaciogenic sandstones and conglomerates of the Aquidauana Formation (Permo- Carboniferous), eolic sandstone and fluvial-eolic conglomerates of the Botucatu Formation (Jurassic-Cretaceous), basaltic rocks of the Serra Geral Formation (Cretaceous), and by siliciclastic rocks of the Bauru Group (Late Cretaceous). All these rocks are covered unconformably, by lateritizated eluvial-coluvial cenozoic sediments. The area was conditioned by tectono-sedimentary events, wich controlled the detritic sedimentary distribution and the diamontiferous placers. The sedimentary facies study was done to characterize the mineralogical assemblage, under the light of a sedimentation associated with continental denudation, and planation surface elaboration. The morphotectonic and morphostructural pattern determine the relief features and the instalation of the drainage network on a structural frame, and allow to interpret the tectono-sedimentary evolution of the region in a neotectonic context. During the Cenozoic, the relief and drainage network instalation were controlled by tectonic structures associated with transtensive (NW-SE and E-W) and transpressive (NE-SW) features. The sequence of different tectono-sedimentary cycles resulted, probably, in erosion of kimberlitic of the Alto Paranaíba Uplift, provinding selection and progressive enrichment of resistent material, stable and ultra-stable rocks and minerals in to the Cretaceous (Bauru Group) and Cenozoic...

Resumo: A região de Franca situa-se na borda nordeste da Bacia do Paraná, sendo margeada a nordeste por um soerguimento regional contemporâneo à individualização da Placa Sul-Americana e abertura do Oceano Atlântico Sul, o Soerguimento do Alto Paranaíba. A área é caracterizada por rochas do Grupo Araxá-Canastra (Pré-Cambriano) sobrepostas discordantemente por, da base para o topo, arenitos e conglomerados glaciogênicos da Formação Aquidauana (Permo-Carbonífero), arenitos eólicos e conglomerados eólico-fluviais da Formação Botucatu (Jurássico-Cretáceo) intercalados por rochas basálticas (derrames e sills) da Formação Serra Geral (Cretáceo), e rochas siliciclásticas do Grupo Bauru (Cretáceo Superior). Estas rochas encontram-se recobertas por sedimentos inconsolidados (Cenozóico), freqüentemente lateritizados. A história geológica mesozóico-cenozóica da região de Franca foi determinada por mecanismos tectono-sedimentares controlando a distribuição da sedimentação detrítica e formação de pláceres diamantíferos. O estudo de fácies sedimentares das unidades mesozóico-cenozóicas permitiu a caracterização das assembléias mineralógicas presentes, sob o enfoque de sedimentação fortemente vinculada a eventos de desnudação continental, com o preenchimento sedimentar de bacias, associado à elaboração de superfícies de aplanamento. O comportamento morfoestrutural e morfotectônico, ao qual as unidades aflorantes foram submetidas, condicionando a morfologia do relevo e a instalação da rede de drenagem num quadro estrutural, permitiu a caracterização da evolução tectono-sedimentar da região, sob um enfoque neotectônico. No Cenozóico, a morfologia do relevo e a instalação da rede de drenagem parecem fortemente controladas por um quadro de estruturas tectônicas... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: The region of Franca is located in the northeastern limits of the Paraná Basin, aside the Alto Paranaíba Uplift, with associated kimbelitic bodies. Its evolution is contemporaneous to the individualization of the South America Plate and by the opening of South Atlantic Ocean. The Mesozoic-Cenozoic geology of the Franca region is characterized by basement rocks of Araxá Group (Pré-Cambrian) overlaid, from bottom to top, by glaciogenic sandstones and conglomerates of the Aquidauana Formation (Permo- Carboniferous), eolic sandstone and fluvial-eolic conglomerates of the Botucatu Formation (Jurassic-Cretaceous), basaltic rocks of the Serra Geral Formation (Cretaceous), and by siliciclastic rocks of the Bauru Group (Late Cretaceous). All these rocks are covered unconformably, by lateritizated eluvial-coluvial cenozoic sediments. The area was conditioned by tectono-sedimentary events, wich controlled the detritic sedimentary distribution and the diamontiferous placers. The sedimentary facies study was done to characterize the mineralogical assemblage, under the light of a sedimentation associated with continental denudation, and planation surface elaboration. The morphotectonic and morphostructural pattern determine the relief features and the instalation of the drainage network on a structural frame, and allow to interpret the tectono-sedimentary evolution of the region in a neotectonic context. During the Cenozoic, the relief and drainage network instalation were controlled by tectonic structures associated with transtensive (NW-SE and E-W) and transpressive (NE-SW) features. The sequence of different tectono-sedimentary cycles resulted, probably, in erosion of kimberlitic of the Alto Paranaíba Uplift, provinding selection and progressive enrichment of resistent material, stable and ultra-stable rocks and minerals in to the Cretaceous (Bauru Group) and Cenozoic...

A margem ocidental de América do Sul é comumente considerada como um exemplo de margem oceano - continental convergente, constituindo a antigo Oeste do Gondwana antes de sua dispersão no Cretáceo. O segmento norte de América do Sul experimento a mudanças drásticas desde o desenvolvimento como bacia de trás-arco no Triássico-Jurássico até formar uma retro-bacia de ante-país no contexto atual andino. Uma maneira para determinar essas mudanças nos eventos geodinâmicos que afetam o segmento norte da América do Sul é estudando a proveniência das rochas sedimentares e reconstruir a evolução do paleodrenagem. Este estudo analisa a proveniência das rochas sedimentares que compõem o intervalo Triássico-Mioceno depositados na Bacia do Huallaga. Foram utilizados os métodos de U-Pb em zircão detrítico e isotopia de Nd-Sr. Os resultados mostram quatro mudanças da proveniência associados a eventos locais e regionais que afetam a bacia de ante-pais do norte de Peru. As rochas sedimentares do Triássico-Jurássico foram depositadas em um contexto de bacia de back-arc. Os valores de εNd (0) são de - 7,9 a -10 associada com um arco juvenil junto com idades U-Pb em zircão detritico que representam as províncias de Greenville- Sunsás (1.3-0.9 Ga), Brasiliano (0.5-0.7 Ga) e Maroni-Itacaiúnas (2-2.2 Ga). Estes resultados sugerem uma fonte de proveniência mista vindo do Arco Vulcânico Mesozoico (Arco Misahuallí-Colán) e rochas Pré-cambrianas da Cordilheira Oriental do Peru e Cordilheira Real do Equador. As rochas sedimentares do Cretáceo (Albiano-Maastrichtiano) têm valores de εNd (0) entre -16 a -18 com picos de idades U-Pb em zircão detritico representando as províncias de Rondônia-San Ignácio (1.3-1.54 Ga), Rio Negro-Juruena (1.54-1.82 Ga) e Ventuari Tapajós (1.82-2 Ga). Estes resultados sugerem uma fonte das áreas do Cráton Amazonico onde o transporte de sedimentos foi realizado no sentido Oeste para Leste durante o Albiano-Maastrichtiano e dominou todo o segmento norte de América do Sul. As rochas sedimentares do Paleoceno Inferior- Eoceno têm valores εNd (0) de - 5,58 a -10,35 com picos de idades U-Pb em zircão detritico que representam as províncias de Greenville-Sunsás (1.3- 0.9 Ga), Brasiliano (0.5-0.7 Ga) e Rio Negro-Juruena (1.54-1.82 Ga) junto com as primeiras populações de zircões com idades mais jovens que 120 Ma. Essas idades representam os primeiros zircões da região dos Andes e corresponde ao segmento da Cordilheira Ocidental. As rochas sedimentares do Oligoceno têm valores de εNd (0) entre -7,7 a -9,9 junto com um pico principal de idades U-Pb entre 23-29 Ma (Oligoceno). Estes resultados mostram uma predominância de fonte de arco vulcânico Paleógeno-Neógeno (Arco Vulcânico Calipuy- Saraguro) que se desenvolve na Cordilheira Ocidental do Equador e do Peru. As rochas sedimentares do Miocene apresentam valores de εNd (0) entre -5,8 a -12,6 junto com idades U-Pb em zircão detritico principais pertencem às províncias Greenville-Sunsás (1.3-0.9 Ga), Brasiliano (0.5-0.7 Ga), Arco Magmático Paleozóico (0.4-0.26 Ga) e Rift Permo-Triassico (0.25-0.15 Ga). Estas rochas apresentam uma fonte mista vindo dos segmentos da Cordilheira Ocidental e Oriental dos Andes Centrais. O desenvolvimento da Cordilheira Oriental gera uma barreira evita o transporte dos sedimentos que veim da Cordilheira Ocidental.
The Andean margin of South America is considered as the type example of an ocean - continental convergent margin, located along the west margin of Gondwana prior to its dispersion during to Cretaceous. The north segment of South America undergoes severe changes from the passage of a back-arc basin during the Triassic-Jurassic to a retro-foreland basin in the current Andean context. One way to constraint the changes of these geodynamical proccesses and the way it affected the northern part of South America is to study the sedimentary provenance and reconstruct its paleodrainage evolution. This study analyzes the sedimentary rocks of the Triassic-Miocene interval deposited in the Huallaga basin that has part of the northern Peruvian Amazonian basin. We performed sedimentary analyzes using the methods of, U-Pb in detrital zircon and Sr-Nd isotopes. The results show 4 changes in provenance associated with regional and local events that affect the northern Peruvian Amazonian basin. The Triassic-Jurassic is characterized by deposition of sediments in back-arc basin context. The Triassic-Jurassic sediments present εNd (0) values of -7.9 to - 10 associated with a young arc along with zircon population age from the representing the provinces of Greenville-Sunsás (1.3-0.9 Ga), Brasiliano (0.5-0.7 Ga) e Maroni-Itacaiúnas (2- 2.2 Ga). These results suggest a mixed source between volcanic arc (Misahuallí-Colán Arc) and Pre-cambrian rocks of the Eastern Cordillera of Peru and Cordillera Real of Ecuador. The sedimentary rocks of the Cretaceous (Albian-Maastrichtian) present εNd (0) values of - 16 to -18 along with zircon population age from the representing the provinces of Rondonia- San Ignácio (1.3-1.54 Ga), Rio Negro-Juruena (1.54-1.82 Ga) e Ventuari-Tapajós (1.82-2 Ga). These results suggest a source of Amazon Craton, where the transport of sediments developed westward from the drainage systems during the Albian-Maastrichtian and dominated the entire northern segment of South America. The Early Paleocene to Eocene sedimentary rocks presents εNd (0) values of – 5.58 to -10.35 with zircon population age from the representing the provinces of Greenville-Sunsás (1.3-0.9 Ga), Brasiliano (0.5-0.7 Ga) e Rio Negro-Juruena (1.54-1.82 Ga) with population age younger than 120 Ma. These ages represent the first zircons from the Andean mountains and correspond to the segment of the Western Cordillera. The Oligocene sedimentary rocks present εNd (0) values of -7.7 to - 9.9 with a main peak of zircon population ages between 23-29 Ma (Oligocene). These results show a predominance of the Paleogene-Neogene volcanic arc (Calipuy-Saraguro Volcanic Arc) source that is developed in the Western Cordillera of Peru and Ecuador. The Miocene sediments present εNd (0) values of -5.8 to -12.6 located in the sediments area of the Altiplano-Eastern Cordillera associated to a mixture sources of volcanic arc and recycled sediments of Phanerozoic and Pre-cambrian rocks. The main peaks of U-Pb ages belong to the Greenville-Sunsás (1.3-0.9 Ga), Brasiliano (0.5-0.7 Ga), Arco Magmático Paleozóico (0.4-0.26 Ga) e Rift Permo-Triassico (0.25-0.15 Ga). These sediments present a mixed source from the segments of the Western and Eastern Cordillera of the Central Andes. Te uplift of the Eastern Cordillera generates a barrier that avoids the transportation of the sediment that comes from the Western Cordillera.
El margen occidental andino sudamericano es comúnmente considerado como un ejemplo de margen océano - continental convergente, constituyendo el antiguo margen Oeste de Gondwana antes a su dispersión en el Cretáceo. El segmento norte de América del Sur experimenta cambios desde el desarrollo de una cuenca de tras-arco durante el Triásico- Jurásico hasta formar una retro-cuenca de ante-país en el actual contexto andino. Una manera para determinar estos cambios en la geodinámica que afectan el segmento norte de Sudamérica es estudiando la procedencia de los sedimentos y reconstruir la evolución de paleodrenaje. El presente estudio de procedencia analiza las rocas sedimentarias que componen el intervalo Triásico-Mioceno depositado en la Cuenca Huallaga que forma parte de la Cuenca Amazónica Norte del Perú. Para este estudio fueron utilizados dataciones U-Pb en circón detrítico e isotopia de Sr-Nd. Los resultados muestran cuatro cambios de procedencia asociados con eventos regionales y locales que afectan la retro-cuenca de antepaís al norte de Perú. Las rocas sedimentarias del Triásico-Jurásico fueron depositads en un contexto de cuenca tras-arco. Los valores de εNd (0) oscilan entre - 7.9 a -10 asociados a un arco juvenil junto con edades principales de U-Pb que representan las provincias Greenville- Sunsás (1.3-0.9 Ga), Brasiliano (0.5-0.7 Ga) e Maroni-Itacaiúnas (2-2.2 Ga). Estos resultados sugieren una fuente mixta entre arco volcánico (Arco Misahuallí-Colán) y rocas Precambrianas de la Cordillera Oriental de Perú y Cordillera Real de Ecuador. Las rocas sedimentarias del Cretáceo Superior (Albiano-Maastrichtiano) presentan valores de εNd (0) entre -16 a -18 junto con picos de edades U-Pb que representan las provincias de Rondônia- San Ignácio (1.3-1.54 Ga), Rio Negro-Juruena (1.54-1.82 Ga) e Ventuari-Tapajós (1.82-2 Ga). Estos resultados sugieren una fuente de Cratón Amazónico donde el transporte de sedimentos se desarrolló en dirección Este para el Oeste durante el Albiano-Maastrichtiano y dominó todo el segmento norte de América del Sur. Las rocas sedimentarias del Paleoceno Temprano-Eoceno presentan valores de εNd (0) entre – 5.58 a -10.35 con principales edades U-Pb que representan las provincias Greenville-Sunsás (1.3-0.9 Ga), Brasiliano (0.5-0.7 Ga) e Rio Negro-Juruena (1.54-1.82 Ga) junto con las primeras poblaciones de edades menores a 120 Ma. Estas edades representan los primeros circones procedentes de la zona andina y corresponde al segmento de la Cordillera Occidental. Los rocas sedimentarias del Oligoceno son caracterizados por presentar valores εNd (0) entre -7.7 a -9.9 junto con un pico principal de edades de U-Pb entre 23-29 Ma (Oligoceno). Estos resultados muestran un predominio de fuente de arco volcánico Paleógeno-Neógeno (Arco Volcánico Calpiuy-Saraguro) que se desarrolla en la Cordillera Occidental de Perú y Ecuador. Las rocas sedimentarias del Mioceno presentan valores εNd (0) entre -5.8 a -12.6 junto con idades U-Pb principales que pertenecen a las provincias Greenville-Sunsás (1.3-0.9 Ga), Brasiliano (0.5-0.7 Ga), Arco Magmático Paleozóico (0.4-0.26 Ga) e Rift Permo-Triassico (0.25-0.15 Ga). Estos sedimentos presentan una fuente mixta procedente de los segmentos de la Cordillera Occidental y Cordillera Oriental de los Andes Centrales. Durante el desarrollo de a Cordillera Oriental genera una barrera que impide el transporte de sedimentos procedentes de la Cordillera Ocidental

This article summarized the exploration ideas and methods for a closer look at the Mesozoic hydrocarbon potential in the Banggai Basin, offshore Matindok, Eastern Arm of Sulawesi. The area is one of the Pertamina EP’s working area which located in the frontier basin that has an acreage exceeding 10,000 sqkm. A major portion of the Mesozoic play in the basin is still under explored, whilst/whereas the existence of an active Cenozoic petroleum system in the offshore Matindok has been confirmed by Tiaka Producing Field. The main challenge in exploring the Mesozoic section in the Matindok Block is imaging it below the ophiolite complex / ultra-mafic layer of the Batui thrust, as well as the thick Neogene carbonate. These barriers inhibit the penetration of seismic energy that resulted in low-quality seismic data beneath the thrust. In order to generate its play concept, massive exploration efforts have been conducted in the Matindok Block since 2017. It consists of onshore geological fieldwork, high-resolution satellite data processing, and the new acquisition of shallow-marine transition 2D seismic data. Potential mature source rocks of the Triassic Tokala marine shale was found in the outcrops nearby the Batui thrust. In the seismic interpretation, the equivalent Jurassic to Cretaceous outcrops that dominated by the fluvio-deltaic sandstones, have been interpreted as pinched-out features along the margin of half graben structures. This area was compressed during the Late Miocene to Plio-Pleistocene shortening events, and intensively imbricated the Cenozoic to present-day sediments on the Batui thrust, but put the Paleozoic - Mesozoic half-grabens beneath the Batui thrust decollement. Finally, the finding of this study is able to demonstrate the petroleum-system risks assessment of the Mesozoic hydrocarbon potential.

The evolution of the 2000 km long Mesozoic rift system underlying the Labrador-Baffin Seaway is described, with emphasis on results from geophysical data sets, which provide the timing, sediment thickness, and crustal structure of the system. The data sets include seismic reflection and refraction, gravity, and magnetic data, with additional constraints provided by near-surface geology and well data. Many features that characterize rift systems globally are displayed, including: wide and narrow rift zones; magma-rich and magma-poor margin segments; exhumation of continental mantle in distal, magma-poor zones; and occurrences of thick basalts, associated with the development of seaward-dipping reflectors, and magmatic underplating. The magma-rich regions were affected by Paleogene volcanism, perhaps associated with a hotspot or plume. Plate reconstructions help elucidate the plate tectonic history and modes of rifting in the region; however, many questions remain unanswered with respect to this rift system.
