O estudo de bacias sedimentares é de grande importância econômica, já que podem servir de reservatórios naturais de água, hidrocarbonetos e minérios valiosos. Neste sentido, avanços significativos vêm sendo feitos na área da engenharia computacional, motivados principalmente pela indústria petrolífera, buscando uma melhor compreensão dos mecanismos envolvidos na formação das bacias, a fim de otimizar custos e minimizar riscos na exploração das mesmas. O objetivo deste trabalho é a modelagem da formação, compactação e deformação de bacias sedimentares abordando exclusivamente os fenômenos mecânicos envolvidos. A simulação pode ser dividida em três fases características: a deposição dos sedimentos, sua compactação devido às forças gravitacionais e alívio de poro-pressões, e as deformações impostas por movimentos tectônicos extensionais e compressivos. Os estudos são realizados a partir de um modelo constitutivo poroelastoplástico em grandes deformações, levando em conta os acoplamentos hidro-mecânico e elástico-plástico. A simulação numérica é realizada através do método dos elementos finitos. Um algoritmo desenvolvido em Fortran é utilizado para realizar simulações bidimensionais da bacia em estado plano de deformação. São apresentados para diferentes momentos os fenômenos de subsidência da rocha sedimentar no caso de movimentos tectônicos extensionais, e de inversão da bacia (uplift) para o caso de movimentos tectônicos compressivos. São analisados e comparados todos os casos: compactação gravitacional e compactação segundo esforços de origem tectônica. / The study of sedimentary basins is of great economic importance, since they can serve as natural reservoirs of water, hydrocarbons and valuable minerals. In this context, motivated mainly by the oil industry, significant advances have been made in the area of computational engineering, seeking a better understanding of the mechanisms involved in the formation of basins in order to optimize costs and minimize risks in their exploration. This work is devoted to modeling of purely mechanical aspects of the formation, compaction and deformation of sedimentary basins. The simulation can be divided into three characteristic phases: the sediments deposition, its compaction due to gravitational forces and pore pressure dissipation, and its deformations imposed by extensional and compressive tectonic motion. The poromechanical constitutive law is formulated in the framework of finite irreversible strains, accounting for hydromechanical and elasticity-plasticity couplings. The numerical simulation is performed using the finite element method. An algorithm developed in Fortran code is used to perform two-dimensional simulations in plane strain state. Two phenomena are presented for different basin ages: the sedimentary rock subsidence, in the case of extensional tectonics, and the basin inversion (uplift), in the case of compressive tectonics. Different analyses and comparisons are made for all cases: gravitational compaction and tectonic-driven compaction.

The objective of this thesis is to compare applications of seismic and geoelectric methods and to state recommendations for their application in future geological prospection, especially application of shallow seismic reflection. Another goal was verification of assumed course of tectonic lines and thickness and character of sedimentary infill, which are important for calculation of seismic hazard by actual standards in context with effort of prolonging licence and also expansion of nuclear power plant Dukovany. When selecting locations for survey there was an effort to confirm the position of the Diendorf-Boskovice zone border and fault zones leading through the zone. The survey was done using multi- electrode electrical resistivity tomography, refraction and reflection seismic.

Le Tian Shan est une chaîne intracontinentale d’Asie Centrale, dont la structure lithosphérique résulte de l’accrétion de divers blocs au cours du Paléozoïque. Son histoire tectonique récente est marquée par sa réactivation au Tertiaire, liée à la collision entre l’Inde et l’Asie. L’histoire topographique et tectonique de la chaine entre les deux orogenèses majeures (paléozoïque terminal et cénozoïque) reste peu contrainte. Cette thèse associe deux approches, la sédimentologie et la thermochronologie basse température, dans le but de déterminer de façon qualitative l’évolution de la topographie au cours du Mésozoïque.Le démantèlement des reliefs associés à la chaine tardi-paléozoïque s’achève au Trias supérieur. Il est suivi d’une activité tectonique très faible au Jurassique, majoritairement transtensive et caractérisée par des taux d’exhumation très faibles dans le Tian Shan. Une surface majeure de pénéplanation se développe alors en Asie Centrale. A la limite Jurassique – Crétacé, la mise en place de cônes alluviaux indique une réactivation de la chaîne, qui n’est néanmoins pas suffisante pour être enregistrée par la thermochronologie. Cette période est caractérisée par un régime généralement extensif en Asie Centrale (jusqu’au Bassin Caspien qui s’ouvre à l’est), et précède la phase d’exhumation lente, qui suit au Crétacé inférieur. La chaîne est progressivement réactivée à partir de 100 Ma et pendant le Crétacé supérieur, ce qui pourrait correspondre à un effet retardé de la collision du Bloc de Lhassa (140 - 120 Ma). Vers 65 - 60 Ma, une phase d’exhumation rapide atteste d’une réactivation plus intense et localisée le long des principales failles. Elle est sans doute liée aux collisions de blocs le long de la marge sud-ouest de l’Asie (e.g. Bloc du Kohistan, arc du Dras, Bloc Afghan). Dans la région du Tian Shan, l’activité tectonique semble totalement s’arrêter au Paléocène permettant le développement d’un niveau majeur de calcrêtes, avant la nouvelle réactivation au Néogène. Par conséquent, l’association des données de thermochronologie sur le socle avec la reconstruction des milieux de dépôt dans les différents bassins, montre que la paléo-chaîne du Tian Shan s’aplanit durant le Mésozoïque. Des évènements tectoniques de faible envergure ont lieu en Asie Centrale, induits par les principaux mouvements géodynamiques le long des bordures entourant l’Asie. Pourtant leur enregistrement est incomplet et seule la combinaison des deux approches étudiées permet de reconstituer l’évolution topographique et paléogéographique du Tian Shan. / The Tian Shan is an intracontinental range located in Central Asia. The structure of the range formed during the Paleozoic through the accretion of several blocks. Recently the range has been reactivated due to far-field effects of the collision between India and Asia. The topographic and tectonic evolution of the range in-between these two major relief-building phases (Late Paleozoic and Cenozoic) is still poorly understood. Two different approaches are combined in this work, in order to determine the Mesozoic topographic evolution of the area, in a qualitative way.The Late-Paleozoic range has been progressively eroded until the Upper Triassic/Lower Jurassic. Tectonic activity was relatively quiet during the Jurassic characterised by low exhumation rates. We suggest that the tectonic regime was dominated by transtension in the Tian Shan area. This period is linked to a regional peneplanation in Central Asia. At the Jurassic-Cretaceous boundary, the occurrence of alluvial fan deposits shows a reactivation of the range, though not strong enough to be recorded by low-temperature thermochronology. This period is characterised by an overall extensional tectonic regime all over Central Asia, with the opening of the Caspian Basin further west. It precedes the phase of very slow exhumation that occurs during the Lower Cretaceous. From 100 Ma and during the Upper Cretaceous, the range is progressively reactivated. We suggest that this correspond to a delayed answer of the Lhassa bloc collision (140 - 120 Ma). Around 65 - 60 Ma, a new phase of rapid exhumation attests of a stronger reactivation, localised along the major faults. This is contemporary of bloc collisions along the south-west margin of Asia, such as the Kohistan Block, the Dras arc or the Afghan Block. In the Tian Shan area, the development of calcrete features in the Paleocene suggests the end of tectonic activity, before the new reactivation in the Neogene.The combination of low temperature thermochronology on the basement rocks and facies sedimentology in the various basins indicate that while during the Mesozoic, the Palaeo-Tian Shan topography generally flattens, some small-scale tectonic events driven by far-field effects of major geodynamic processes around the edges of Asia did occur. However, those tectonic movements did not induce enough exhumation to be recorded by low temperature thermochronometers. Only the sediment record allows their detection and detailed description.

It has been hypothesized that authigenic carbonate minerals, formed within the pore spaces of marine siliciclastic formations during early diagenesis, may have had a substantial influence on the global carbon cycle, particularly in times of low oxygen in Earth history. According to this idea, alkalinity is generated via anaerobic organic matter degradation, resulting in carbonate oversaturation and the precipitation of low δ13C carbonate cements. If a substantial amount of 13C-depleted carbonate was sequestered in this authigenic sink, the δ13C of dissolved inorganic carbon (DIC) in the global ocean would be driven to more positive values without significant organic carbon burial - a signal which would be recorded in marine carbonates. Research presented herein tests this hypothesis from newly acquired lithostratigraphic and coupled stable carbon and oxygen isotope data of Upper Devonian limestone and black shale formations preserved within the Western Canada Sedimentary Basin. The Late Devonian includes a mass-extinction event, and is characterized by pervasive ocean anoxia and a dramatic reduction in platformal carbonate sediment deposition. As such, it has been hypothesized to represent an ideal time for the emergence of an active authigenic carbonate sink. Results show that both basinal shale (Besa River and Exshaw formations) and platform carbonates (Wabamun Group and its equivalents), record a δ13C signal that is within the expected range of Devonian seawater (3‰ to -2‰), signifying that precipitated authigenic carbonate had no influence on the isotopic composition of DIC. It was observed, however, that evaporitic depositional settings can accumulate carbonate sediment with low δ13C values (down to -8.4‰), potentially caused by local water column organic matter respiration during prolonged water-mass residence in a restricted marginal marine setting. If such depositional environments were globally pervasive, such as during during global sea-level lows, it is plausible that the carbon isotope mass balance would be affected. / Graduate / 2021-06-18

<div> <div> <div> <p>The combination of field-based studies and numerical modeling provides a robust tool for evaluating geologic and geodynamic processes along a convergent margin. Complex and persistent tectonic activity and a novel suite of geophysical observations make the southern Alaskan convergent margin a key region to evaluate these processes through both basin analysis studies and geodynamic modeling. This conceptual approach is utilized to explore the active driving forces of surface deformation throughout southcentral Alaska, as well as the geologic record of regional Cenozoic tectonic processes. </p> <p>New sedimentologic, chronostratigraphic, and provenance data from strata that crop out within the central Alaska Range document a previously unrecognized stage of Eocene – early Miocene strike-slip basin development along the northern side of the central Denali fault system. This stage was followed by Miocene-Pliocene deformation and exhumation of the central Alaska Range, and basin development and northward sediment transport into the Tanana foreland basin. This portion of the study provides insight into Cenozoic tectonics and basin development in the central Alaska Range. </p> <p>How transpressional tectonics are manifest in the modern-day, in combination with shallow subduction processes, are not well understood for the southern Alaskan convergent margin. Simulations of the 3-D deformation of this region allow for investigation of the complex relationship between these tectonic processes and surface deformation. Results from this study display the far-field affect that strong plate coupling along the shallowly subducting Yakutat slab has on the surface deformation of southcentral Alaska. Our models also show that partitioning of this convergence is observed along the Denali fault system. Additionally, our results indicate the subducting slab is segmented into separate Pacific, Yakutat and Wrangell slab segments. This variation in slab structure exerts control on the upper plate response to shallow subduction.</p> </div> </div> </div>

Over a decade ago, it was discovered that the earth’s natural seismic wavefields, propagating as seismic noise, can be processed using correlation methods to produce surface waves, similar to those generated by earthquakes. This discovery represents a paradigm shift in seismology and has led to several tomographic studies of earth structures, at different scales and resolutions, in previously difficult-to-study areas around the world. This PhD dissertation presents research results on multi-scale and multi-purpose applications of ambient seismic noise wavefields under three topics: (1) Imaging of sedimentary basins and sub-basin structures in eastern and western Canada using ambient seismic noise, (2) Combining measurements from ambient seismic noise with earthquake datasets for imaging crustal and mantle structures, and (3) Temporal variation in cultural seismic noise and noise correlation functions (NCFs) during the COVID-19 lockdown in Canada. The first topic involved imaging the sedimentary basins in eastern and western Canada using shear wave velocities derived from ambient noise group velocities. The results show that the basins are characterized by varying depths, with maximums along the studied cross-sections in excess of 10 km, in eastern and western Canada. Characteristics of accreted terranes in eastern and western Canada are also revealed in the results. A seismically distinct basement is imaged in eastern Canada and is interpreted to be a vestige of the western African crust trapped beneath eastern Canada at the opening of the Atlantic Ocean. In western Canada, the 3D variation of the Moho and sedimentary basin depths is imaged. The thickest sediments in eastern Canada are found beneath the Queen Charlotte, Williston and the Alberta Deep basins, while the Moho is the deepest beneath the Williston basin and parts of Alberta basin and northern British Columbia. For the second topic, I worked on improving the seismological methodology to construct broadband (period from 2 to 220 s) dispersion curves by combining the dispersion measurements derived from ambient seismic noise with those from earthquakes. The broadband dispersion curves allow for imaging earth structures spanning the shallow crust to the upper mantle. For the third topic, I used ambient seismic data from the earlier stages of the COVID-19 pandemic to study the temporal variation of seismic power spectra and the potential impacts of COVID-19 lockdown on ambient NCFs in four cities in eastern and western Canada. The results show mean seismic power drops of 24% and 17% during the lockdown in eastern Canada, near Montreal and Ottawa respectively and reductions of 27% and 17% near Victoria and Sidney respectively. NCF signal quality within the secondary microseism band reached maximum before the lockdown, minimum during lockdown and at intermediate levels during the gradual reopening phase for the western Canada station pair. / Graduate

A Bacia de Jaibaras, localizada no nordeste do Brasil, faz parte de um sistema de rifts ediacarano a cambriano desenvolvido, em grande parte, sob a Bacia do Parnaíba, como demostram os dados geofísicos. Esta bacia teve o seu desenvolvimento estreitamente ligado ao sistema de falhas do Lineamento Transbrasiliano, representado nas suas bordas. No presente trabalho foi realizada a análise estrutural do preenchimento vulcano-sedimentar da bacia visando à reconstituição da evolução dos campos de paleotensões atuantes durante a sua instalação e deformação. O estudo foi sustentando essencialmente em observações feitas em campo e complementado com o exame de dados de sísmica de reflexão, gravimetria e magnetometría. Deste modo procurou-se contribuir na discussão sobre a classificação da bacia, tópico amplamente discutido mas até então não abordado sob a perspectiva do tectonismo gerador e deformador da Bacia de Jaibaras. A instalação da bacia esteve marcada provavelmente pelo mesmo campo de esforços distensivos de direção NNW-SSE responsável pela intrusão do enxame de diques Coreaú. Em seguida, esta direção regionalmente sofreu rotações que determinaram a continuidade da instalação, deformação e inversão do rift. As estruturas na Formação Pacujá, de idade EdiacaranoCambriano, mecanicamente coerentes com este estágio, compreendem falhas de direção NE-SW reativadas com sentido transcorrente dextral, com componente normal; falhas de direção ENE-WSW sin- e pós-sedimentares e falhas de transferência de direção NW-SE. Associadas à propagação das falhas de direção ENE-WSE sin-sedimentares formaram-se dobras. Dobras também ocorrem em posição transversal a estas falhas relacionadas com deslocamento diferenciais nas rampas de revezamento. Estas estruturas ensejaram a criação de um sistema de drenagem axial, um sistema deltaico associado às rampas de revezamento e cones de talude transversais. Na Formação Parapuí, coetânea, ocorrem múltiplas famílias de veios de calcita. A mais antiga apresenta direção N-S e foi preenchida sob a ação de campo de esforços distensivo na direção ENE-WSW. Posteriormente formaram-se veios de calcita de direção E-W, tentativamente correlacionados com as falhas sin-sedimentares da Formação Pacujá, originadas por uma distensão de direção aproximada N-S. Na Formação Aprazível se registram diques clásticos de idade ordoviciana que seriam coerentes com uma direção distensiva NW-SE. Um campo de esforços compressivo E-W a ENE-WSW atuante a partir do Ordoviciano tardio gerou estruturas transpressivas ao longo de certos segmentos de direção ENE-WSW, ocasionando uma fraca inversão da bacia. Este evento está representado por dobras cônicas de arrastro geradas durante a inversão de falhas normais para reversas, com componente transcorrente. Na Formação Parapuí este evento pode ter determinado a formação de veios de calcita de direção ENE-WSW com componente dextral e veios sigmoidais en échelon com a mesma orientação. Tanto na Formação Pacujá como na Formação Parapuí está registrado um evento final representado por fraturas abertas de orientação aproximada E-W (distensão de direção N-S), que encontrariam correlação com o campo de esforços obtido pela orientação de diques clásticos na Formação Ipu (Siluriano) da Bacia do Parnaíba, assim como o arranjo de juntas híbridas medidas na mesma formação. A importância da atividade de falhas transversais produto das movimentações transcorrentes ao longo do sistema de falhas do Lineamento Transbrasiliano leva a considerar que a cinemática transcorrente foi desencadeadora da subsidência no rift e posteriormente da deformação durante a inversão. Por estes motivos, com relação à classificação da Bacia de Jaibaras considera-se que esta estaria mais próxima de uma bacia de pull-apart do que um rift puro. / The Jaibaras Basin, in northeastern Brasil, is a part of an Ediacaran to Cambrian rift system that branches under the Parnaiba sag basin, as evidenced by geophysical data. The basin is closely related to the Trasnbrasiliano Lineament fault system, represented in both its boundaries. The present study comprises a structural analysis of the volcano-sedimentary infill of the basin, aiming to the reconstruction of the paleostress field evolution responsible for the installation, deformation and inversion of the basin. This analysis was supported by sedimentological observations in the field and complemented with revision of seismic lines, gravimetric and magnetometric maps. The study aims to contribute to the discussion of the classification of the basin, a widely reviewed topic but few times from a sedimentary infill deformation perspective. The Jaibaras Basin initiation was probably related to the samestress field responsible for the intrusion of the Coreaú dyke swarm under a NNW-SSEoriented paleostress field. Subsequently the paleostress field rotated causing both the deformation and inversion of the rift. In the Ediacaran to Cambrian Pacujá Formation were identified several mechanically consistent structures with the NNW-SSE-oriented paleostress field: longitudinal NE-SW-oriented faults with right-lateral strike-slip reactivation with a normal component; transverse ENE-WSW-oriented faults with both syn- and- post- sedimentary activity and transfer NW-SE-oriented faults. Associated with the ENE-WSW-oriented syn-sedimentary faults normal fault-propagation-folds formed. Additionally transverse folds were formed related to the differential slip along the normal faults. The above-described structures determined the installation of an axial drainage system, a deltaic setting associated to rely ramps and transversal talus cones. In the contemporary Parapuí Formation, locally occurred the formation N-S-oriented calcite veins caused by an ENE-WSW-oriented extensional paleostress field. Then followed the formation of the E-W-oriented calcite veins tentatively correlatable to the syn-sedimentary faults in the Pacujá Formation, formed under an approximately N-S-oriented extension. In the Ordovician Aprazível Formation were identified clastic dykes, coherent with a NW-SEoriented extension. An E-W- to ENE-WSW-oriented paleostress field acting from the Late Ordovician generated transpressive structures along certain ENE-WSW-fault segments, related with the mild inversion of the basin. This event is represented by conic drag folds in the Pacujá Formation related to the inversion of normal faults, with a strike-slip component. In the Parapuí Formation, this event might have determined the formation of ENE-WSWoriented veins with right-lateral strike-slip component and sigmoidal en échelon veins with the same orientation. Both in the Pacujá and Parapuí formations were identified a final event represented by E-W-oriented open fractures (N-S-oriented extension). These are correlatable to the paleostress field obtained for the NE-SW-oriented clastic dikes registered in the Ipú Formation of the Serra Grande Group (Silurian) of the Parnaiba Basin, as well as the conjugate hybrid joint arrangements measured in the same formation. The importance of the activity of the transverse faults, caused by the strike-slip kinematics along de Transbrasiliano fault system leads to consider that were these kinematics the trigger of the subsidence in the rift and subsequently the deformation during the inversionprocess. Therefore, in relation to the classification of the basin it is here considered that the Jaibaras is more closely related to a pull-apart basin than a pure rift.

Este trabalho tem como objetivo mapear os aquíferos sedimentar e cristalino na bacia sedimentar do Paraná no Estado de São Paulo, por meio do emprego da Inversão Conjunta de dados obtidos em sondagens com os métodos TDEM (Eletromagnético no Domínio do Tempo) e Eletrorresistividade por meio da técnica de SEV (Sondagem Elétrica Vertical). Os estudos foram realizados na região de Termas de Ibirá, distante cerca de 450 km do Município de São Paulo. Nesta região os poços tubulares perfurados captam água principalmente do aquífero sedimentar raso (Aquífero Bauru) relacionado com os sedimentos arenosos da Formação Adamantina, Grupo Bauru. Por outro lado, o aquífero fraturado na camada de basalto da Formação Serra Geral (Aquífero Serra Geral) ainda é pouco conhecido, sendo que este último constitui-se num excelente alvo para exploração de água subterrânea. Com as SEVs, obtiveram-se as informações mais rasas dos arenitos do Grupo Bauru, o Aquífero Bauru e o topo dos basaltos da Fm. Serra Geral. Com o método TDEM o pacote basáltico pôde ser investigado com maior detalhe e o Aquífero Serra Geral caracterizado. A análise dos resultados foi feita por meio da Inversão Conjunta-1D de sondagens SEVs/TDEM, de modo que as informações de cada metodologia foram integradas complementarmente, isto é, todo o intervalo de profundidade pôde ser caracterizado: a parte mais rasa com os dados das SEVs e a mais profunda com os dados do TDEM. Os resultados foram integrados com informações litológicas de poços de exploração de água subterrânea catalogados no SIAGAS-CPRM. Esta integração diminuiu as ambiguidades inerentes ao processo de interpretação de dados geofísicos, permitindo a demarcação de três zonas de favorabilidade para o posicionamento de poços tubulares profundos visando a exploração de água subterrânea no Aquífero Serra Geral e cinco zonas de favorabilidade para o Aquífero Bauru. Também foi possível caracterizar o comportamento estrutural da litoestragrafia na área de estudo. Deste modo, esses resultados contribuíram para o desenvolvimento das pesquisas hidrogeofísicas no Estado de São Paulo. / This work presents the geophysical mapping of sedimentary and fractured aquifers in Parana Sedimentary Basin, in Sao Paulo State, Brazil, obtained by 1D - Joint Inversion of TEM (Transient Electromagnetic) soundings and VES (Vertical Electrical Soudings). The studies were conducted in Termas de Ibira region, in Ibira City, which is located 450 km northwest of the city of Sao Paulo. The groundwater exploration wells in the area are located mainly into the shallow sedimentary aquifer (Bauru Aquifer), whose sediments and rocks are related to Adamantina Formation, Bauru Group. On the other hand, the fractured aquifer inside the basalts of Serra Geral Formation (Serra Geral Aquifer) is still not well known and has a huge groundwater exploration potential. The VES results can investigate the shallow sandstones from Bauru Group, the Bauru Aquifer and the top of Serra Geral basalt layer. The TEM soundings investigate the deepest depth interval inside the basalt layer and can examine in detail the fractured aquifer (basalts). The result analysis were integrated by 1D - Joint Inversion of VES/TEM soundings pairs, where the information of each depth interval was used in a complementary way, i.e., the Joint Inversion used the VES to solve shallow information and the TEM soundings the deepest information. Moreover, the results were integrated with the lithological information from the groundwater exploration wells registered in SIAGAS-CPRM database. The integration between Joint Inversion results and the lithological well information could decrease the inherent ambiguities in the geophysical interpretation process, and allowed to map five groundwater exploration favorabitility zones in the Bauru Aquifer and three favorability zones in the Serra Geral Aquifer. The results also provided the structural behavior of the area lithostrigraphy. Furthermore, this study can contribute to the development of hydrogeophysical research in countryside of Sao Paulo State.
