Resumen: Durante el Neoproterozoico tardío y el Paleozoico, el actual segmento argentino-chileno de la Cordillera de los Andes y desde finales del Paleozoico la Península Antártica, formaron parte del margen suroccidental de Gondwana. Durante este periodo de tiempo, a dicho margen se fue acrecionando un conjunto de fragmentos continentales de tamaño y aloctonía variable, dando lugar en el Paleozoico a seis orogenias de diferente extensión temporal y espacial: Pampeana (Ediacárico-Cámbrico temprano), Famatiniana (Ordovícico Medio-Silúrico), Chánica (Devónico Medio-Carbonífero temprano), Oclóyica (Ordovícico Medio-Devónico), Gondwánica (Devónico Medio-Pérmico medio) y Tabarin (Pérmico tardío-Triásico). Todas estas orogenias son colisionales, salvo la Tabarin y la Gondwánica al sur de los 38º S.Palabras clave: Evolución geodinámica, Paleozoico, Andes argentino-chilenos, Península Antártica, Orógeno Oclóyico, Orógeno Famatiniano, Orógeno Chánico, Orógeno Gondwánico, Orógeno Tabarin.Abstract: During the late Neoproterozoic and Paleozoic times, the Argentine-Chilean Andes, -and since the late Paleozoic the Antarctic Peninsula,- formed part of the southwestern margin of Gondwana. During this period of time, several continental fragments of variable extensión and allochtonie were successively accreted to that margin, resulted in six Paleozoic orogenies of different temporal and spatial extension: Pampean (Ediacaran-early Cambrian), Famatinian (Middle Ordovician-Silurian), Chanic (Middle Devonian-early Carboniferous), Ocloyic (Middle Ordovician-Devonian), Gondwanan (Middle Devonian-middle Permian) and Tabarin (late Permian-Triassic). All these orogenies had a collisional character, with the exception of the Tabarin and the Gondwanan south of 38º S.Keywords: Geodynamic evolution, Paleozoic, Argentine-Chilean Andes, Antarctic Peninsula, Ocloyic orogen, Famatinian orogen, Chanic orogen, Gondwanan orogen, Tabarin orogen.

Abstract:
The Paleozoic and post-Paleozoic radiations of crinoids present an opportunity to explore genomic and ecological explanations for patterns of morphologic diversification. Analysis of discrete-character data that cover the principal features of the crinoid skeleton shows that both Paleozoic and post-Paleozoic increases in morphological disparity were abrupt; this is consistent with rapid exploitation of open ecological opportunities in both cases. For the post-Paleozoic, this result is sensitive to some aspects of data analysis and sampling, so it cannot be regarded as unequivocal. The deceleration in morphological diversification within each radiation is consistent with an observed decline in rates of taxonomic origination as well as with the attainment of functional or structural limits. Despite these similarities in the two radiations, Paleozoic crinoids exploited a wider range of morphological designs than did their post-Paleozoic successors. Post-Paleozoic crinoids exploited a wide range of ecological strategies despite being stereotyped in many aspects of form. This difference between the radiations is consistent with an increase in the rigidity of genetic and developmental systems. The range of post-Paleozoic designs is not in essence a subset of the Paleozoic spectrum. The two radiations resulted in morphological distributions that are largely nonoverlapping, perhaps reflecting a different range of ecological strategies.

Abstract:
The following problem is solved by the present research: the probable sources of Paleozoic hydrocarbon deposits are determined on the basis of modeling the hydrocarbon foci of generation Paleozoic-Mesozoic oil source formations (for example, the southeast of Western Siberia, Tomsk Region). The research area is the lands Ostanino field group: the Selveikin area of deep drilling, the Ostaninskoye and Gerasimovskoye oil and gas condensate fields. Pre-Jurassic strata with oil source potential, including the Paleozoic Larinskaya (S1lr), Mirnaya (D13mr), Chuzikskaya (D2cz), Chaginskaya (D3cg) and Kehoregskaya (C1kh) formations, as well as Jurassic Bazhenovskaya (J3bg) and Tyumenskaya (J1-2tm ) formations, and, accordingly, the reservoirs of the weathering crust and bed-rock Paleozoic reservoirs are the objects of study. The subject of analysis was selected in accordance with the concept of the geothermal regime of the subsoil, as a leading factor in the implementation of the generation potential of the parent sediments. The research methods are digital paleotemperature modeling and historical-geological analysis. The results and conclusions concerning the fundamental problems of “Paleozoic oil” are obtained. 1. Source of the Paleozoic oil deposits can be both the Domanic type rocks of the Paleozoic formations and the Jurassic oil source formations. Thus, both upward vertical interstratal HC migration and downward HC migration can take place. Therefore, the two concepts of “main source” are compatible and should not be considered, as often, orthodoxly alternative. 2. The domanicoid rocks of the Paleozoic formations are most likely the source for Paleozoic gas and gas condensate deposits. 3. Paleozoic formations the roof of the bed-rock Paleozoic (on the Ostankinskaya group of fields – C1kh and D3cg) can be only the source of the «Paleozoic oil» and gas deposits in the Pre-Jurassic oil and gas complex. 4. Bazhenov formation – J3bg may be the “Jurassic” source of oil deposits in the Pre-Jurassic oil and gas complex. The results were obtained and conclusions were drawn concerning the applied (search) aspects of the problem: 1. Results additionally substantiate the author’s search criterion for the oil and gas content of the Paleozoic – these are anomalous geophysical and petrophysical characteristics of the Jurassic section. 2. The absence of hydrocarbon deposits in the Jurassic section is most likely a negative sign of the Paleozoic oil and gas content. 4. The low density of the modern heat flow (less than 40 mW/m2) is most likely a negative sign of oil deposits in the Paleozoic. 3. High paleotemperatures in terms of VR (more than 175oC) are most likely a negative sign of oil and gas deposits in the Paleozoic. 4. Reasons have been obtained to state that oil deposits in the Paleozoic cannot be richer than oil deposits in the Jurassic.

Abstract:
Over two hundred years ago the Swedish scientist Carl Linnæus (1781), in an analysis of the biogeographic patterns of living organisms, suggested that all species originated in Paradise. Although there has been considerable progress in the understanding of biogeographical patterns during the intervening two centuries, modern debate has focused on the general applicability of the concept of faunal realms together with the relevance of dispersal, panbiogeographic, and vicariance models (Nelson and Platnick, 1981). To date, studies of Paleozoic brachiopod biogeography have no strong theoretical base; rather the various numerical techniques available, including both cladistic and phenetic methodologies, have helped organize the growing amount of distributional data into recognizable and useful structures.

Full text
Abstract:
Numerous diatremes of middle and late Paleozoic age intrude miogeoclinal middle and lower Paleozoic strata in the Canadian Cordillera. In addition to abundant crustal xenoliths and conspicuous mantle-derived mineral xenocrysts, rare zircon grains are present. U–Pb dating of single zircon crystals from many of these diatremes has failed to identify the presence of cogenetic (magmatic) zircons. All dated zircon grains are interpreted as xenocrysts derived from the crust. Their morphologies range from euhedral to very rounded, and their ages range from early Paleozoic to Archean. Most ages fall between 1.8 and 2.1 Ga, with subordinate age groupings in the late Archean (ca. 2.6 Ga), Middle Proterozoic (1.0–1.1 Ga), and early Paleozoic (ca. 470 Ma, 530 Ma). The Proterozoic and Archean zircons could have been derived from either the crystalline basement or its overlying sedimentary cover of Late Proterozoic to early Paleozoic age. Paleozoic zircons were probably derived from either intrusions within the basement or sills that intrude the early Paleozoic sedimentary cover, and they signify magmatic activity possibly related to rifting of the continental margin.

Full text
Abstract:
Changes in genus diversity within higher taxa of marine animals on the temporal scale of a few million years are more strongly correlated with changes in extinction rate than with changes in origination rate during the Paleozoic. After the Paleozoic the relative roles of origination and extinction in diversity dynamics are reversed. Metazoa as well as individual higher taxa shift from one mode of diversity dynamics to the other. The magnitude of taxonomic rates, the relative variance of origination and extinction rates, and the presence or absence of a long-term secular increase in diversity all fail to account for the shift in importance of origination and extinction in diversity changes. Origination and extinction rates both tend to be diversity-dependent, but different modes of diversity-dependence may contribute to the change in diversity dynamics from the Paleozoic to the post-Paleozoic. During the Paleozoic, there is a weak tendency for extinction rates to be more diversity-dependent than origination rates, whereas after the Paleozoic the two rates are about equally diversity-dependent on average.

Abstract:
Lacertasterias elegans and Schondorfia fungosa are new genera and species of multiarmed asteroids described from the Kinderhookian? (Mississippian) Gilmore City Formation of Iowa and the Chesterian (Mississippian) Haney Formation of Illinois, respectively. Based on ambulacral construction, the former belongs to the Paleozoic asteroid stem group whereas the latter is distinct from but closer to post-Paleozoic asteroids.The multiarmed condition is atypical today; nevertheless, multiarmed species are morphologically varied and taxonomically widely distributed. The condition is considered problematic; it is uncertain whether or not multiarmed organization is adaptively neutral. Although only convergent with rather than ancestral to post-Paleozoic multiarmed asteroids, both new genera share important similarities with modern multiarmed predators, implying a predatory life mode for the fossils. The similarity between phylogenetically disparate Paleozoic and post-Paleozoic asteroids implies the multiarmed condition is beneficial, and benefits endured in spite of the major biotic changes that occurred around the end of the Paleozoic.

Se ha realizado una investigación de los depósitos de tipo sedex que se encuentran en las series paleozoicas del SW de los Catalánides (España). Los principales depósitos están encajadas en pizarras negras llandoverienses del Bosc de Poblet, y en las series carboníferas del Priorat. Para cada depósito o grupo de depósitos de ha realizado una caracterización detallada, a nivel estructura, mineralógico, geoquímico e isotópico, y microtermométrico (inclusiones fluidas). La mayoría de depósitos consisten en tramos de sulfuros masivos alternando con tramos de niveles feldespáticos criptocristalinos. Se han identificado asociaciones ricas en Cr-V y en plationoides, concretamente para los depósitos de edad silúrica. El resultado de los estudios siotópicos de Pb y Sm-Nd confirman el carácter singenético de las mineralizaciones. La mineralización se atribuye a una actividad hidrotermal submarina, para los distintos depósitos. En el caso de los de edad silúrica, esta actividad tuvo lugar en una cuenca euxínica lo cual favoreció la acumulación de numerosos elementos (V-Cr-U), en una posición distal respecta a las zonas de alimentación. La deposición en la cuanca carbonífera fue en una posición relativamente mas proximal, y el fluido mineralizante era agua marina que circulaba convectivamente en el seno de la cuenca. Se ha atribuido un origen exhalativo para explicar la génesis de los niveles feldespáticos. Se considera la posibilidad de que estos se hubieran formado en la pluma hidrotermal, por interacción entre componentes hidrotermales y agua marina.

Abstract:
The Neoproterozoic and Paleozoic evolution of global climate, tectonics, ocean geochemistry, and biological diversification are recorded in stratigraphic successions globally. The rock record of southwestern Mongolia has potential to reveal additional constraints as it is in the early stages of exploration. It has been known for several years that Cryogenian passive margin sedimentation on the Zavkhan Terrane hosts evidence for Neoproterozoic glaciation, and that overlying early Cambrian strata host rich records of small shelly fossils; however, the geological context for these critical records has been previously lacking. Although these unknowns can be regarded as local geologic uncertainties, together they hold implications to test existing tectonic and crustal growth models of the Central Asian Orogenic Belt (CAOB), preservation potential of geochemical proxies within carbonate dominated strata, and biologic milestones as recorded in Paleozoic sediments. To understand and interpret the above implications, methods of field geology, litho- and chemo-stratigraphy, geochemistry, petrography, fluid inclusion and clumped isotope thermometries, and U-Pb zircon geochronology were used. As a result, the tectonic origin and travels of the Zavkhan Terrane during the Neoproterozoic to early Paleozoic is refined and models of apparent crustal growth in the CAOB are re-assessed. Global Cryogenian and Ediacaran carbon and strontium isotope curves are constructed from limestonedominated successions of the Tsagaan-Olom Group of the Zavkhan Terrane and are integrated with available geochronologic and geochemical data from around the globe. Finally, dolomitization is shown to greatly alter primary geochemical signatures, including carbon isotope values of carbonate rocks.

Abstract:
Soil seed banks are a reservoir of viable seeds present in the soil in plant communities. They have been studied and characterized in various ways in different habitats. However, these studies are limited to modern seed banks. This study extends seed bank studies to the Paleozoic Era. It was hypothesized that size distribution and seed density in Paleozoic seed banks exhibit similar patterns as in modern seed banks. Seed sizes and seed density of fossil seed from Wise Virginia were estimated. Modern seed bank information was obtained from published data. Data were analyzed using one-way ANOVA and Kruskal-Wallis test. The Paleozoic size distribution was predominated by larger seeds and the estimated seed density of 19 200 seeds m-3 falls within the range of modern seed banks but at a higher end of modern seed bank densities. During the Paleozoic they were sufficient to insure regeneration of these economically important forests.

Abstract:
L’estudi del registre sedimentari i paleontològic del fini-Carbonífer, Permià i Triàsic continentals dels Pirineus Catalans han permès caracteritzar-ne l’evolució paleoambiental i paleoclimàtica i la seva repercussió sobre els ecosistemes terrestres durnt la transició Paleozoic–Mesozoic. Aquesta transició, marcada per diversos canvis climàtics i extincions en massa, s’ha analitzat mitjançant un estudi multidisciplinari. Les diverses campanyes de camp han resultat en el descobriment de fins a deu noves localitats amb restes fòssils, principalment amb icnites de tetràpodes (de les quals se’n fa especial èmfasi), però també amb restes òssies, traces fòssils d’invertebrats i plantes. Fins al present treball es coneixien molt pocs jaciments de petjades d’aquestes edats als Pirineus Catalans. L’elaboració de columnes estratigràfiques i cartografies de detall ha permès establir la successió espacio-temporal dels jaciments i de les unitats geològiques corresponents (unitats deposicionals definides en treballs anteriors). L’estudi conjunt d’icnites i fàcies contribueixen a realitzar anàlisis paleoambientals. L’estudi del registre fòssil ha implicat l’establiment de diferents biozonacions, que s’ha complementat amb anàlisis paleomagnètiques, cicloestratigràfiques, mineralògiques i elementals. El Carbonífer superior s’ha documentat a partir de l’associació de plantes de la Unitat Grisa, que indiquen una edat d’Estefanià C. Les dades sedimentològiques i de paleosòls indiquen un clima humit amb curts períodes de sequera. El trànsit Carbonífer–Permià (Unitat de Trànsit) ve marcat per un increment en l’estacionalitat i l’aridesa. La manca de marcadors cronològics als afloraments estudiats no permet precisar l’edat de la unitat. El Permià inferior constitueix l’inici de les successions de red-beds. Els paleosòls dels dipòsits volcanosedimentaris de la Unitat Roja Inferior i l’absència de carbó denoten una aridificació del clima i una estacionalitat marcada. Els esporàdics intervals més humits, representats per sistemes fluvials meandriformes i dipòsits derivats d’aigua d’escolament superficial, contenen una icnoassociació de tetràpodes característica de l’Artinskià i constituïda per: Batrachichnus salamandroides, Limnopus isp., cf. Amphisauropus, cf. Ichniotherium, Dromopus isp., cf. Varanopus, Hyloidichnus isp., Dimetropus leisnerianus i tres tipus de Characichnos (traces fòssils de natació). Les traces fòssils d’artròpodes (especialment Rusophycus i Acripes) també són comunes. El registre del Permià mitjà denota unes condicions climàtiques humides i estacionals. El sistema al·luvial distal de la Unitat Roja Superior inferior ha lliurat poques restes fòssils. La presència d’una vèrtebra assignada al grup dels casèids suggereix una edat de Wordià inferior i, juntament amb les icnites de tetràpode documentades en treballs previs, constata un reemplaçament de faunes. El Permià superior es caracteritza per un clima semi-àrid, tal com indiquen les dades sedimentològiques, mineralògiques i elementals de la Unitat Roja Superior superior. El sistema de playa-lake o lacustre efímer mostra un control orbital de la sedimentació. La icnoassociació de tetràpodes documentada marca un reemplaçament de les faunes del Permià mitjà, possiblement lligat a una extinció. El Triàsic Inferior i Mitjà està representat pel sistema fluvial (de rius braided a meandriformes i planes d’inundació) de la unitat en fàcies Buntsandstein, que conté una icnoassociació de tetràpodes formada per: Prorotodactylus mesaxonichnus (erigida com a nova icnoespècie), cf. Rotodactylus, Rhynchosauroides cf. schochardti, Rhynchosauroides i chirotheriids indeterminats, un morfotip indeterminat (Morfotip A) i dos tipus de Characichnos associats a la nova icnoespècie i als chirotheriids. Aquest registre fòssil es complementa amb la presència de dues dents d’arcosauromorf i marca la recuperació dels ecosistemes terrestres després de l’extinció de finals del Permià, amb els arcosauromorfs com a grup cabdal. El registre continu als trànsits Carbonífer–Permià i Permià–Triàsic (fins ara desconegut al sudoest europeu), així com també la inesperada riquesa fòssil, fa dels Pirineus Catalans una regió de referència a nivell global per comprendre alguns dels canvis més dràstics de la història de la Terra.
The sedimentary and paleontological record study of the terrestrial end-Carboniferous, Permian and Triassic from the Catalan Pyrenees allowed to characterize its paleoenvironmental and paleoclimatic evolution and their influence on the terrestrial ecosystems during the Paleozoic–Mesozoic transition. This transition, featured by several climatic changes and mass extinctions, has been analyzed in a multidisciplinary study. Diverse fieldworks have resulted in the discovery of up to ten new fossil localities, mainly bearing tetrapod ichnites (here especially emphasized), but also bearing bone remains, invertebrate trace fossils and plants. Until the present work, few fossil footprint sites were known from these ages in the Catalan Pyrenees. The detailed stratigraphic columns and cartography allowed to establish the spatio-temporal succession of fossil sites and of the corresponding geological units (depositional units defined in previous works). The coupled study of ichnites and facies contribute to carry out paleoenvironmental analyses. The study of the fossil record implied the establishment of different biozonations, which have been complemented with paleomagnetic, cyclostratigraphic, mineralogical and elemental analyses. The late Carboniferous has been documented by the Grey Unit plant assemblage, indicating a Stephanian C age. The sedimentological and paleosol data point to a humid climate with short dry periods. The Carboniferous–Permian transition (Transition Unit) is featured by increases in seasonality and aridity. The lack of chronological markers in the studied outcrop precludes to clarify the age of the unit. The early Permian constitutes the beginning of the red-bed successions. Paleosols developed in the Lower Red Unit volcanosedimentary deposits and the absence of coal denote climate aridification and strong seasonality. Sporadic relatively humid intervals, depicted by meandering fluvial systems and deposits derived from unconfined runoff water, yield a tetrapod ichnoassemblage characteristic of the Artinskian and composed of: Batrachichnus salamandroides, Limnopus isp., cf. Amphisauropus, cf. Ichniotherium, Dromopus isp., cf. Varanopus, Hyloidichnus isp., Dimetropus leisnerianus and three types of Characichnos (swimming trace fossils). Arthropod trace fossils (especially Rusophycus and Acripes) are also common. The middle Permian record denotes humid climatic conditions and seasonality. Few fossil remains have been reported from the lower Upper Red Unit distal alluvial system. The presence of a vertebra assigned to the caseid group suggests an early Wordian age and, together with tetrapod ichnites documented in previous works, a faunal replacement is confirmed. The late Permian is characterized by a semi-arid climate, as indicated by the sedimentological, mineralogical and elemental data of the upper Upper Red Unit. Deposits of the playa-lake or ephemeral lacustrine system show orbital forcing during sedimentation. The documented tetrapod ichnoassemblage marks a replacement of the middle Permian faunas, possibly linked to an extinction. The Early and Middle Triassic is recorded by the fluvial system (from braided to meandering rivers and floodplains) of the Buntsandstein facies unit, which yields a tetrapod ichnoassemblage composed of: Prorotodactylus mesaxonichnus (erected as a new ichnospecies), cf. Rotodactylus, Rhynchosauroides cf. schochardti, undetermined Rhynchosauroides and chirotheriids, an undetermined Morphotype A and two types of Characichnos associated to the new ichnospecies and to chirotheriids. This fossil record is complemented with the presence of two recovered archosauromorph teeth and is indicative of the terrestrial ecosystems recovery after the end-Permian mass extinction, being archosauromorphs a relevant group. The continuous record throughout the Carboniferous–Permian and Permian–Triassic transitions (so far unknown from southwestern Europe), as well as the unsuspected fossil richness, make the Catalan Pyrenees a reference region worldwide to untangle some of the most drastic changes of Earth history.

In SPE/AAPG Africa Energy and Technology Conference. SPE, 2016. http://dx.doi.org/10.2118/afrc-2566974-ms.

Full text
Abstract:
ABSTRACT This paper focuses on the tectonic evolution of the North African petroleum basins as the controlling factors on the major basins’ formation, evolution and the hydrocarbon accumulation, analyzing the petroleum enrichment conditions and proposing hydrocarbon accumulation mode. The analysis concludes that the distribution of North Africa Basins is in regular east-west direction, clear depression associates with highland structure. The basins becomes gradually older from the west to the east, corresponding to the Western Paleozoic basin, the Middle part Paleozoic and Mesozoic superimposed basin and the Eastern Mesozoic-Cenozoic rift basin. Petroleum in the Middle-West basins is mainly controlled by western Hercynian tectonic movement with obvious NE – SW distribution character, while petroleum in the East basins controlled by the Alpine tectonic movement, showing NW-SE distribution. Experienced a number of north-south direction reversals, the Paleozoic basin developed in the South and the Mesozoic-Cenozoic superimposed basin overlaying the Paleozoic Basin located in the North. The basins have two different accumulation models, which are younger source rocks associated with the older reservoirs and the older source rocks with the younger reservoirs.

Full text
Abstract:
Lower Paleozoic strata occur offshore Labrador (Middle to Upper Ordovician), offshore Baffin Island in western Davis Strait (Upper Ordovician), as well as onshore Baffin Island (Cambrian to Silurian). Paleozoic carbonate rocks (limestone and dolostone units) dominate with occurrences of siliciclastic strata found in the offshore Labrador subsurface (in the Freydis B-87 well) and in outcrop on Baffin Island. In the Labrador-Baffin Seaway, Lower Paleozoic strata primarily exist as isolated erosional remnants, where historically, minimal effort has been made to correlate Paleozoic outliers due to their lateral discontinuity coupled with inconsistent age data. The Lower Paleozoic of the Labrador-Baffin Seaway and Baffin Island can be viewed as two subsets that do not appear to be correlatable: the southern Lower Paleozoic of the Labrador margin and the northern Lower Paleozoic of the southeastern Baffin Shelf and onshore Baffin Island.
