Повний текст джерелаLes plate-formes cratoniques, larges et peu profondes, furent le lieu, au Dévonien, de la première colonisation des aires continentales par les faunes et les flores. Ces événements sont bien enregistrés à l’ouest de la Libye dans les sédiments déposés le long de l’arche cratonique de Gargaf qui sépare les bassins de Ghadames et de Murzuk. Cette étude décrit les lithologies, la diagenèse, les surfaces-clés, l’empilement des séquences de dépôts de ces sédiments à l’affleurement et en subsurface dans le bassin de Ghadames. La distribution régionale des sédiments est comparée aux bassins environnants et à l’enregistrement mondial pour discuter le rôle des contrôles tectoniques locaux et régionaux sur l’évolution des paléopaysages et des paléosurfaces continentales. Ces résultats fournissent des indications clés et sur le fonctionnement des larges plate-formes cratoniques et leurs conséquences sur la localisation et l’origine des roches mères et des réservoirs pétroliers

Повний текст джерелаThe Caim Formation consists of shallowing upward hemicycles (fifth order). These are grouped into larger, broadly shallowing upward trends (fourth order). The Caim Formation and the overlying Peechee Member represent a single third order depositional sequence deposited during an overall period of sea-level rise. The dominantly retrograding buildup margins of the Peechee Member also reflect the influence of rising sea-level, punctuated by relative stillstands. Reciprocal siliciclastic basin sedimentation and buildup carbonate sedimentation characterized Peechee buildup margins.
The dominantly retrograding buildup margins of the Fairholme Group are characteristic of transgressive systems tracts. Buildup margins developed progradational or vertically aggradational geometries due to prevailing circulation patterns and the manner of basin filling.

Повний текст джерелаO trabalho consiste na análise estratigráfica do intervalo siluro-devoniano da Bacia do Amazonas utilizando como base os conceitos da Estratigrafia Moderna, mais especificamente a sequência estratigráfica genética, proposta por Galloway (1989), a qual utiliza as superfícies de inundação marinha como os limites de uma sequência sedimentar. A principal razão para a utilização desta metodologia deve-se ao fato que o conteúdo rochoso compreendido no intervalo estudado teve a sua sedimentação relacionada às transgressões marinhas que faziam parte do contexto paleogeográfico da bacia durante o Siluriano e Devoniano. Desta forma, as superfícies de inundação máxima, representativas de eventos cronoestratigráficos, destacam-se nos perfis de raios gama e são tomadas como datum de correlação em treze poços exploratórios, os quais foram distribuídos em quatro seções (A-A, B-B, C-C e D-D) pela bacia. A análise destas seções permitiu a identificação de quatro sequências de terceira ordem (AB, BC, CD e DE), limitadas no topo e na base por superfícies de inundação marinha. Cada sequência é constituída por ciclos regressivo-transgressivos assimétricos, representados pelo trato de sistemas de mar alto e pelo trato de sistemas transgressivo. A análise destas seções integrada à interpretação de mapas estratigráficos (isópacas, isólitas e porcentagem de areias) possibilitou identificar o depocentro da bacia, bem como duas áreas principais como fonte de sedimentos arenosos (uma a oeste e outra a sul). Além disto, foi possível inferir que a comunicação marinha com o continente, durante as transgressões paleozoicas, responsável pela deposição de sedimentos pelíticos, seguiu uma orientação de norte para sul, evoluindo obliquamente em direção ao continente num trend nordeste para sudoeste. Por fim, a partir da análise cíclica em perfis de raios gama, as superfícies de inundação marinha, do intervalo Devoniano, das bacias do Amazonas e Parnaíba foram correlacionadas.

Повний текст джерелаIn this study we investigated the taphonomic and stratigraphic analyses of the basal layers of Sequence B (Neopraghiano / Eoemsiano), Ponta Grossa Formation, with a focus on Curva II outcrop, Ponta Grossa, Paraná, which until then had not been studied under these aspects. The objective is to provide a description and interpretation of the above mentioned outcrop, as well as the inclusion of its layers in stratigraphic framework of the sequence. In order to obtain more accurate data, the methodology used to collect data was of taphonomic high-resolution. The fauna here considered is a typical representative of the Malvinokaffric Realm and occurs distinctly along the Curva II outcrop. Three different taphocenosis representing different sedimentary environments have been identified. The data obtained in this study were integrated into the areas of occurrence of fossiliferous outcrops adjacent to Curva II. A combined analysis of the taphonomic, paleontological and stratigraphic aspects, followed by a reinterpretation of the outcrops in northeastern urban area of Ponta Grossa, inserts the Curva II outcrop above sections of the UEPG Campus, as well as Francelina I, II and III and below sections of Curva I and Franco da Rocha, which are representatives of a transgressive process, in a situation of sedimentary retrogradation which occurred in the passage Neopraghiano/Eoemsiano in the Ponta Grossa Formation, filling, thus, a gap in the stratigraphic sequence of the base of sequence B.
Na presente pesquisa buscou-se a análise estratigráfica e tafonômica das camadas basais da Sequência B (Neopraguiano/Eoemsiano), Formação Ponta Grossa, com enfoque no afloramento Curva II, Ponta Grossa, Paraná, que até então não havia sido estudado sob estes aspectos. Objetivou-se a descrição e interpretação do afloramento citado bem como a inserção de suas camadas no arcabouço estratigráfico de sequências. Com o intuito de se obter dados mais precisos, utilizou-se metodologia de coleta de alta resolução tafonômica. A fauna aqui analisada é representante típica do Domínio Malvinocáfrico e ocorre distintamente ao longo do afloramento Curva II tendo sido identificadas três diferentes tafocenoses que representam distintos ambientes de sedimentação. Os dados obtidos nesta pesquisa foram integrados aos de áreas de ocorrência fossilífera adjacentes ao afloramento Curva II. Com uma análise conjunta entre os aspectos tafonômicos, paleontológicos e estratigráficos e após uma reinterpretação dos afloramentos da região nordeste do perímetro urbano de Ponta Grossa, insere-se o afloramento Curva II acima das seções Campus UEPG e Francelina I, II e III e abaixo das seções Curva I e Franco da Rocha, sendo representantes de um processo transgressivo, em situação de retrogradação sedimentar ocorrida na passagem Neo-praguiano/Eo-emsiano da Formação Ponta Grossa, preenchendo, desta maneira, uma lacuna na coluna estratigráfica de sequências local da base da Sequência B.

Повний текст джерелаEste trabalho é o resultado da análise estratigráfica de detalhe sobre o registro sedimentar do intervalo Praguiano Emsiano Superior, realizada em amostras testemunhadas por quatro poços, na seção d e afloramentos paleozóicos da borda leste da Bacia do Paraná. A integração dos dados foi realizada a partir das informações obtidas através de sedimentologia, gamaespectrometria e geoquímica orgânica (carbono orgânico total e pirólise Rock-Eval). Desta forma, foram identificados eventos deposicionais de variadas freqüências, classificados como duas seqüências deposicionais de 3 ordem, denominadas B e C, e seis seqüências de 4 ordem, denominadas B1, B2, B3 , B4, C1 e C2. Estes eventos deposicionais representam as variações relativas do nível do mar, ocorridas durante o intervalo estudado, expressas nos tratos de sistemas e superfícies estratigráficas identificados. Em algun s casos, estas variações ocorreram com acentuada ciclicidade no tempo. A cor relação dos poços ao longo de uma seção NS possibilitou a discussão sobre a continuidade lateral dos máximos transgressivos nas seqüências de 3 e 4 ordens. Possibilitou, também, discorrer sobre possíveis fatores locais condicionantes da sedimentação, e sobre as dinâmicas ambiental e sedimentar, na área de estudo. A avaliação dos atributos faciológicos, integrados as ferramentas utilizadas, possibilitou indagar acerca dos principais controles sobre as condições de circulação de sedimentos, de oxigenação da coluna dágua e de preservação da matéria orgânica. Estes métodos em conjunto indicam condições ambientais consideradas marinhas normais, pontuadas por momentos de redução na oxigenação, sem, no entanto, registrar eventos de efetiva anoxia do ambiente de sedimentação. Estas informações sobre a estratigrafia de seqüências, sedimentologia e geoquímica são importantes no estudo da distribuição dos níveis com potencial de geração de hidrocarbonetos, a fim de prospectar áreas mais favoráveis, ao longo da Bacia do Paraná.
This work is the result of detailed stratigraphic analysis on the sedimentary record of Praguian?Emsian later interval, established on core samples of four wells in the Paleozoic outcrop section, eastern edge of Paran? Basin. Data set was obtained by means of sedimentology, gamma spectrometry and organic geochemistry (total organic carbon and pirolysis Rock-Eval), and lately integrated. Thus, depositional events with varied frequencies have been identified. These depositional events were classified as being two depositional sequences of 3rd order, termed as ?B? and ?C?, and six sequences of 4th order, termed as ?B1?, ?B2?, ?B3?, ?B4?, ?C1? and ?C2?. These depositional events typify the relative sea level variations occurred during the studied interval. They were characterized by the systems tracts and stratigraphic surfaces identified. Sometimes, these variations occurred with high cyclicity through the time. The correlation of the wells of a N-S section made possible the discussion about the cont inuity and lateral expression of the transgressive and regressive maximums in the depositional sequences of 3rd and 4th orders, besides the possible local factors which conditioned the sedimentation and the environmental and sedimentary dynamics. The evaluation of facies attributes, integrated with the utilized tools, helped on the inquiring of the main controls on the sediment circulation, water column oxygenation ratio, and organic matter preservation. These data in set indicated normal marine environmental conditions, with punctuated moments of reduction in oxygenation ration, without, however, show effective anoxic events in the sedimentation environment. These informations about the sequence stratigraphy and sedimentology are important in the study of distribution of levels with hydrocarbons generation potential, throughout of Paran? Basin.

Resumo: A Formação Punta Negra (Meso- Neodevoniano da Pré-Cordilheira Argentina) consiste em uma espessa sucessão de depósitos siliciclásticos de água profunda. Esta unidade aflora por cerca de 300 km em direção N-S nas províncias de San Juan, Mendoza e La Rioja. Uma detalhada análise sedimentológica permitiu identificar seis litofácies depositadas pela ação de fluxos de densidade concentrados e correntes de turbidez. Três associações de fácies foram descritas e interpretadas: i) preenchimento de canais: camadas de arenito fino, com escassas estruturas e preenchendo feições erosivas, correspondentes a canais pouco espessos como sistema de aporte em uma rampa proximal; ii) lobos proximais: sucessões estrato-crescentes de camadas arenosas maciças na base e com estruturas de tração no topo, amalgamadas ou interacamadadas com níveis de lamito laminado, correspondendo a deposição de lobos num contexto de rampa proximal; iii) lobos distais/franjas: sucessões de lamito e camadas descontinuas de arenito muito fino que constituem os depósitos mais finos de todo o intervalo estudado, associados ao contexto de rampa distal. Os corpos sedimentares pertencentes às associações de fácies constituem elementos com características geométricas próprias. Os canais são do tipo deposicionais e pouco erosivos, os lobos deposicionais caracterizam corpos de geometria lobada/linguoide apresentando ciclos de compensação de espessuras. Por fim, os depósitos de franjas possuem grande extensão areal e com heterogeneidade acentuada pelo interacamadamento lamito/arenito. Com base na análise de fácies e associação de fácies e em informações levantadas por estudos anteriores, propõe-se um modelo de sistema deposicional turbidítico de rampa submarina rico em areia, caracterizado por um sistema de canais pouco espessos que atuam na forma de múltiplos pontos de aporte. A característica textural imatura dos sedimentos, a abundância de fragmentos vegetais e a deposição de estruturas típicas de fluxos de mais longa duração, são argumentos para propor um sistema de alimentação por meio de fluxos hiperpicnais provenientes diretamente do continente
Abstract: The Punta Negra Formation (Middle to Late Devonian of Argentine Precordillera) is a thick succession of siliciclatic deep-water deposits. This unit outcrops for c. 300 km along north-south direction in the provinces of San Juan, Mendoza and La Rioja. Detailed sedimentological permitted to identify six lithofacies deposited by concentrated density flows and turbidity currents. Three facies associations were described and interpreted: i) channel-filling deposits: massive fine grained sandstone erosive depressions that represent multiple shallow channels in a ramp system; ii) proximal lobes: thickening-upward successions of fine grained massive sandstone beds with a upper portion of very fine laminated sandstone; these beds are amalgamated or interbedded with laminated mudstone and represent depositional lobes in a proximal ramp context; iii) distal lobes/fringe: interstratifications of mudstone and very fine sandstone that are associated to a distal ramp. The channels are constituted of multiple depositional and minor erosional events. The depositional lobes include linguoid bodies with compensation cycles. The fringes have large extension and are characterized by thin interbedding of mudstone/discontinuous very fine sandstone. It was proposed a sand-rich deep-water ramp depositional model, which is characterized by a system of multiple minor erosive channels (multiple source). The immature sediments, the abundance of vegetal fragments and the typical structures of relative long-lived flows evidence a depositional system fed by hyperpicnal flows probably originated of major fluvial floods

The Upper Devonian Catskill Formation represents marginal marine and alluvial sediments which prograded into the Appalachian Basin during the Acadian Orogeny. Distributive fluvial systems (DFS) are prevalent in modern actively aggrading basins in all tectonic and climatic regimes and may be common in the rock record. In this study, I reinterpret the Catskill Formation as a prograding distributive fluvial system (DFS) on the basis of up-section variability in paleosols, channel sandstone textural trends, and alluvial architecture. At least three distinct pedotypes representative of prevailing soil forming conditions are identified during deposition of the Irish Valley, Sherman Creek, and Duncannon Members of the Catskill Formation. Increased paleosol drainage is inferred from an up-section transition from hydromorphic aqualfs within the Irish Valley Member to non-calcareous, uderts within the Duncannon Member. Qualitative field observations of channel sandstone morphology show an increase in channel size up-section. Channels occur as small isolated bodies at the base of the section, transitioning to relatively larger, amalgamated channels, and finally, large isolated channel bodies up-section. Sandstones are litharenites and coarsen-upward throughout the Catskill Formation overall. This coarsening upward trend results from increasing paleo-flow competency in larger channels up-section. These results are consistent with deposition of the Catskill Formation by DFS processes and demonstrate the utility of paleopedological analysis in interpreting alluvial depositional processes. Identifying DFS in the rock record has implications for paleosol-based paleoclimatic studies, as paleosols forming on prograding DFS have increased paleosol drainage up-section, which could potentially be misinterpreted as a shift from prevailing humid to arid paleoclimatic conditions. Recognition of DFS in the rock record also has implications for basin analysis and exploration of fluvial aquifers and hydrocarbon reservoirs, as the stratigraphic architecture of DFS are fundamentally different from tributary systems at the basin scale.

Повний текст джерелаDevonian fossils of infaunal lingulid brachiopods (lingulids) are the main study object of the present dissertation. Taphonomic and stratigraphic data, associated with the record of the Devonian lingulids were collected. The main factors influencing the choice of this group as the subject of study were: abundance of specimens, their different occurrence forms, absence in some outcrops, and the presence of extant species (i.e.similar animals that live at present and that can cooperate with (paleo)biological, (paleo)ecological and taphonomical studies of the fossil forms). Thirty-two outcrops were analyzed in terms of their lithologies and sedimentary structures; when possible, high resolution taphonomic data was obtained and sequence stratigraphic analyses were preformed on the outcrops. Every fossil specimen found was properly considered, i.e. there was no tendency to collect only lingulids. The investigated outcrops pertain to the Devonian succession of the sedimentary Paraná Basin; presently they occupy the Campos Gerais phytogeographic region, Paraná State, Brazil. A taphonomic database was constructed to analyze the collected material. During the period at the Virginia Tech Institution, scanning electron microscope with energy dispersive x-ray was used to analyze lingulids of exceptional preservation. During this same period, statistical analyses were applied to Devonian and Miocenic/Eocenic fossil material containing lingulids. Visits to some museum collections were done with comparative aims, once the taxonomic problematic of the Devonian lingulids had already entered the dissertation list of issues. The main hypothesis of the present dissertation are linked to the following possibilities: (1) the use of recent lingulids to interpret the Devonian lingulid record; (2) that lingulid intrinsic characteristics (i.e. chitinophosphatic shell, infaunal life habit) could act as agents of preferential preservation in different depositional contexts; and (3) the taphonomic analysis being dependent of a true lingulid taxonomy. The obtained results indicate that actualistic data can be used but within these careful paramaters: (1) Devonian lingulids were more biomineralized (though not implying that they were thicker) when compared to recent ones, which could enhance the preservation potential of the fossil lingulids and would affect their taphonomy (this could explain the presence of fragmented lingulids in the Paleozoic record); (2) there is a negative analytical bias accounting for the absence of fragmented lingulids in Cenozoic record; (3) the intrinsic lingulid characteristics can be used as a key to recognize specific depositional environments, over successive systems tracts; and (4) the correct taxonomic identification helps to avoid taphonomical interpretative errors. In the present case, the lingulid type(s) of preservation did not help to achieve an accurate diagnosis of the genus. It was possible, instead, to abolish Lingula and use Lingularia cf. to refer to the Devonian lingulids of the Paraná Basin.

Повний текст джерелаThe Lower Devonian Bokkeveld Group is the Middle unit of the tripartite Cape Supergroup, which outcrops along the western, southern and eastern coastline of South Africa. A well-established sedimentary and stratigraphic understanding of the Bokkeveld Group allowed for geochemical and geochronological investigation in order to gain insight into the provenance characteristics, as well as the paleotectonic environment of the provenance areas. In order to observe any changes within the Bokkeveld Basin, complete profiles for geochemical investigation were sampled in the western, southern and eastern parts of the basin, and compared. Major and trace element patterns suggest that the western part of the basin received detrital input from felsic, magmatically evolved, and possibly alkaline sources, and that the sediment was highly recycled before deposition. Furthermore, the geochemistry suggests that the western part of the basin experienced “passive margin” type sedimentation. The geochemistry of the southern basin, in contrast, suggests input from less evolved, non-alkaline sources, and predicts sedimentation under “active margin” conditions for the lower part of the group. The eastern basin is geochemically intermediate between the western and southern basins. Zircon populations for the three parts of the basin further suggest that sources of different ages fed the three parts of the basin. The zircon population of the western basin suggests that the Namaqua Natal Belt (Mesoproterozoic) and Neoproterozoic cover successions were the major source of detritus, with only minor input from Paleozoic sources. The eastern basin also appears to have sourced mainly Namaquan aged material as well as Neoproterozoic material, with no Paleozoic input. The southern basin has a remarkably different zircon population, with the majority of grains being Paleozoic in age, and only a few Neoproterozoic and Mesoproterozoic grains. Furthermore, many of the grains are younger than any known source-rocks on the Kalahari Craton, and thus allude to input from an extra-Kalahari source into the southern part of the basin. The youngest grain from the southern basin overlaps with the established depositional age of the Bokkeveld Group, suggesting some syn-depositional or briefly pre-depositional magmatic activity in the source area(s) of the southern basin, as predicted by the geochemistry. The complete lack of zircon ages older than the Namaqua Natal Belt (Mesoproterozoic), would suggest that the Archean to Paleoproterozoic inner part of the Kalahari Craton, the Kaapvaal Craton, was not sourced by the Bokkeveld Group. This is most likely due to the Namaqua Natal Belt having served as a large east-west trending morphological divide during Bokkeveld deposition, preventing transport of detritus from the craton interior. Remarkably, this would suggest that the Namaqua Natal Mountain Range must have survived erosion and persisted as a morphological boundary for ca. 600 Ma to serve as the major source of detritus for the Bokkeveld Group. Even an extensive, craton-fringing sedimentary cover-succession such as the Bokkeveld Group, may thus not provide a “detrital fingerprint” of the craton interior, and paleogeographical implications must be taken into consideration during provenance studies. Paleocurrent directions for the Bokkeveld Group indicate a west to east transport direction in the southern part of the basin, and as such, a western, extra-Kalahari source, most likely the Rio de La Plata Craton and surrounds, is expected to have been the source of both the young Paleozoic zircons, as well as undifferentiated material as revealed in the geochemistry.
