Just as in deep-water sedimentary environments, productive source rocks can be developed an evaporitic platform, where claystones are interbedded with evaporites and carbonates. However, the impact of paleoenvironment on organic matter enrichment shallow water evaporite series has not been well explored. In this study, two wells central uplift Tarim Basin were systematically sampled analyzed fo...

The Yarkand Basin, located in the southwest of Tarim is a northeastern part eastern Paratethys ocean Paleocene, and significant amount evaporites, with gypsum, anhydrite, halite as main types, were developed this area. These evaporites record sedimentary environment at that time. A study was conducted on sulfur isotopic composition gypsum Paleocene Basin to explore origin interpret environment....

Abstract A new gravity survey (1164 stations and 180 samples for density analysis) combined with two geological cross sections has been carried out in a sector of the Central Pyrenees order to improve characterization basement cover architecture. From North South, study area comprises southern half Axial Zone northernmost part South-Pyrenean Zone. New data were previous existing databases obtai...

The geometry, kinematics and dynamics of fold-and-thrust belts are strongly influenced by the mechanical behaviour basal décollement. However, many also include mechanically weak lithologies such as evaporites marls or mudstones at different levels within shortened stratigraphy. dynamic evolution these thrust controlled both décollement units embedded overlying stratigraphic succession. In Zagr...

Even being the more studied of interior basins Northeast Brazil, Araripe Basin still lacks research in organic geochemistry designed to support interpretations depositional systems and conditions formation. This work aims investigate behavior evaporites shales from Santana Group (Lower Cretaceous), as well discuss their role evolution its systems. A total 23 samples, 17 six evaporites, were col...

Evaporites are typically described as impermeable seals that create some of the world's highest reservoir pressures beneath salt seal. However, several laboratory studies demonstrate evaporites can retain open pore spaces hydraulically connect sediments above and below them in sedimentary basins. During Messinian Salinity Crisis (5.97–5.33 Ma), up to 2,400 m thickness were rapidly deposited Wes...
