Mass-transport deposits (MTDs) result from gravity-induced mass failure and downslope movement of rock and sediment, spanning various temporal and spatial scales. MTDs originate from triggers that can be seismogenic, inducing rapid emplacement of single MTDs or, in some cases, occurring slowly enough to span significant sedimentation atop the defor...
Conference Paper
Glaciation and deglaciation elevate the probability of subaquatic landslides in marine and lacustrine basins. Glacial-related factors contributing to instability include base-level changes, high sedimentation rates, meltwater floods, and seismic activity linked to glacioisostatic adjustments (GIA). These mechanisms have been studied as potential tr...
Chapter
Sediment remobilization of seafloor strata is linked to the early stages of sediment burial, diagenesis and fluid migration in different geological settings. It can impact the depositional architecture of a sedimentary basin by promoting local and widespread erosion while, in parallel, lead to an overall redistribution of near-seafloor strata (the...
Book
Deepwater Sedimentary Systems: Science, Discovery and Applications helps readers identify, understand and interpret deepwater sedimentary systems at various scales – both onshore and offshore. This book describes the best practices in the integration of geology, geophysics, engineering, technology and economics used to inform smart business decisio...

Abstract The transition from the Late Paleozoic Ice Age (LPIA) to fully postglacial conditions in SW Gondwana is under increasing discussion due to either the radiometric ages of its boundary or the stratigraphic nature of this transition. The record of this transition in the Paraná Basin is found in the glacial and glacially influenced deposits of...
Article
Mass transport deposits (MTDs) contain deformation structures often that are used to determine the kinematics of palaeo-mass flows and hence the orientation of the original slope or gradient upon which the mass flow developed. When integrated with stratigraphic data, the azimuth of the palaeoslope can help elucidate the depositional evolution and p...

Os depósitos de transporte em massa (MTDs) resultam de importantes processos de remobilização e ressedimentação em ambiente subaquático. Esses depósitos são recorrentes ao longo de seção estratigráfica do Grupo Itararé. Portanto, são considerados importantes elementos deposicionais para compreender a evolução tectonoestratigráfica da Bacia do Paran...
Article
Mass-transport deposits (MTDs) may show a variety of deformation aspects, from poorly-deformed layers to highly deformed and homogenized deposits, as a result of the different kinds of mass-transport processes involved in their evolution. Previous studies indicate that the downslope flow transformation of MTDs is characterized by increasing disaggr...
Article
This paper describes facies relationships and stratigraphic architecture of early Permian deglacial deepwater to fluvio-deltaic deposits exposed in the eastern border of the Paraná Basin, southern Brazil. The studied succession is located in the Rio do Sul depocenter and comprises an upward transition between the topmost interval of the Itararé Gro...

The late Bashkirian to lower Sakmarian deposits of the Itararé Group (Paraná Basin, southern Brazil) compose the thickest, most extensive and one of the longest records of the Late Paleozoic Ice Age (LPIA) among the late Paleozoic glaciated basins. The upper Itararé Group (Taciba Formation) cropping out in the northeast Paraná State is studied and...

Most ice-age diamictites were emplaced in basinal settings by non-subglacial processes. Nonetheless, the occurrence of diamictite in rock successions is widely employed to estimate ice extent and delimit glacial growth-decay cycles that serve as background for paleoclimate modeling. We report a cyclic diamictite-mudstone succession from the Bashkir...
Article
This paper examines a glacial diamictite-bearing succession from the upper Itararé Group (Taciba Formation) in eastern Paraná Basin, Brazil. The object of study provides the opportunity to investigate in detail the late stages of glacial sedimentation during the Late Paleozoic Ice Age (LPIA) in this sector of SW Gondwana, with implications for glac...

RESUMO: Depósitos de transporte em massa, formados por fluxos gravitacionais em massa, são extremamente variáveis e apresentam complexo registro estrutural ainda não bem compreendido. O entendimento desses depósitos, tanto sobre o aspecto estratigráfico quanto estrutural, tem importância no estudo paleoambiental e paleogeográfico de depósitos antig...

In this contribution we explore recent advances from ongoing research on the interplay between tectonics and climate in the evolution of the Paraná Basin from the mid-late Carboniferous to the earliest Permian, a time characterized by intense climatic and tectonic instabilities in SW Gondwana. Latest Devonian to Pennsylvanian uplifting on the easte...

RESUMO: Injectitos são intrusões de sedimentos, principalmente areia, causadas pelo aumento da pressão de fluidos, liquefação dos sedimentos e sua injeção na rocha encaixante. Comumente denominados de diques clásticos, essas estruturas podem ocorrer também na forma soleiras ou corpos irregulares ou como vulcões sedimentares quando há extravasamento...

O clímax da era glacial neopaleozoica ocorreu no Pensilvaniano (Neocarbonífero), cujos registros acham-se em bacias de vários continentes. Por outro lado, registros eopermianos de glaciação, que testemunham o final da era glacial, são relativamente mais raros e menos compreendidos dentro do contexto paleogeográfico gondwânico. Neste trabalho é anal...

Depósitos de transporte em massa compõem parcela importante do registro geológico marinho profundo. Esses depósitos, formados sobretudo pela ação de deslizamentos e escorregamentos submarinos, são extremamente variáveis e apresentam um complexo registro estrutural relativamente pouco estudado. No Grupo Itararé da Bacia do Paraná ocorrem depósitos d...

This study presents a qualitative and quantitative analysis of porosity in deformation bands by applying X-ray micro-computed tomography in conjunction with microstructural analysis. Samples of compactional cataclastic bands and shear compactional bands identified in Early Cretaceous aeolian sandstones of the Paraná Basin were analyzed. The applica...
