Epeiric seas were common in deep times, but modern analogues are rare. Large-scale
reconstruction of ancient examples is usually limited by available data, which also hampers …

Abstract The Aptian Romualdo Formation (Araripe Basin, NE Brazil) was deposited in a
restricted epeiric sea, during the opening of the South Atlantic Ocean, with a coeval record to …

Fine-grained rocks have historically been interpreted as a product of the settling of fine
fractions in low-energy environments. However, recent studies have suggested that in these …

Abstract The Jurassic-Cretaceous Mendoza Group is one of the most distinctive
lithostratigraphic units of the widely surveyed Neuquén basin. This work focuses on its …

Deposition of black shales occurred under specific conditions that need to combine in a
precise way the rate of production and the rates of destruction and dilution of organic matter …

Salinity, a key property of watermasses, is difficult to reconstruct in paleodepositional
systems, and errors in assigning salinity facies to epicratonic and marginal-marine deposits …

Lacustrine mudstones are usually considered as deposited dominantly through vertical
suspension fallout in low-energy environments influenced by only occasional fine-grained …

In this paper we describe for the first time the calcareous dinoflagellate cysts and
calpionellid associations from upper Valanginian-Hauterivian orbital-driven rhythmic distal …

O interesse em coquinas aumentou nos últimos anos devido à descoberta dos reservatórios
Barremianos-Aptianos do Pré-Sal das bacias de Campos e Santos, porção offshore da …

Abstract Fine-grained sedimentary deposits (< 125 µm)(ie, fine-grained sandstones to
mudstones (< 4 µm)), play a significant role in hydrocarbon development, geothermal …
