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...
The success of oil and gas exploration in deep and ultra-deep marine environments critically hinges on the discovery of effective stratigraphic traps, where turbidite pinch-outs play a central role and pose a considerable exploration challenge. The characteristics of the margins of sheet sands are important at all stages of exploration, appraisal,...
This field guide provides a detailed outcrop logistics, access and description of the sand-rich turbidite deposits of the Taciba Formation (Rio do Segredo Member), the uppermost unit of the Pennsylvanian Itararé Group (Paraná Basin), which crops out in the Santa Catarina State, southern Brazil. This area has become a classic destination for profess...
The Early Cretaceous chronostratigraphic positioning of the northeast Brazilian basins is mainly based on ostracod distribution, including a biozoning proposal of local stages. The ostracod species were recovered from shales and siltstones samples along Gameleira, Manguinhos and Praia da Falha outcrops of the Maracangalha Formation (Recôncavo Basin...
The long-standing view on the Cretaceous climate zones suggests the inception of an Equatorial Humid Belt (EHB) in the Albian. This inception contrasts with recent sedimentological and palynological evidence of sustained low-latitude, wetter paleoenvironment in the South American and African landmasses during the Aptian. The trigger for this early-...
The rooted nature of vegetation allows for individual plants or entire communities to be buried in life position under exceptional geological conditions, thereby preserving their ecology and spatial distribution in the stratigraphic record. Upright lycopsids are not uncommon within paleoequatorial Carboniferous coal-bearing deposits, but they are r...
The Upper Carboniferous–Lower Permian glacigenic deposits of the Itararé Group (Paraná Basin) are widely known and cover an extensive area in the southern Brazil. These deposits consist of different arrangements of massive shales, diamictites, rhythmites, and fine- to medium-grained sandstones with trough cross-stratification. Five genetically dist...
