The fissility is the ability of some rocks to split along relatively smooth surfaces parallel to the bedding. This property observed mostly in fine-grained rocks is particularly expressed in outcrops, where rocks are subjected to weathering processes. Mo...

The conventional sedimentological model suggests that the accumulation of organic-rich fine-grained sedimentary rocks (<62.5 µm) is uniquely associated with fallout processes in low energy depositional environments. This contribution analyzes organic-...

The Vaca Muerta Formation in the Cerro Domuyo area shows an interesting intercalationof facies with opposite paleocurrents. The unit is represented by outer ramp to basinal facies with a westward directionof progradation. However, in its middle section, ...

An important marine reptile-bearing locaLity from the Tithonian-Berriasian of the central Neuquén Basin (La Yesera deL Tromen, Neuquén Province, Argentina) is studied. This fauna is located in the lower portion of the Vaca Muerta Formation, which is comp...
