Eolian permian deposits in west and northwest

The sedimentary and stratigraphic characteristics of eolian Permian deposits exposed in Mendoza, La Rioja and San Juan Provinces (west and northwest Argentina) are described in this paper. The eolianites are fine and medium sandstones with large-scale cross-bedding, multiple parallel truncation planes and some asymmetrical ripples. Three genetic types of deposits have been identified: dune

Characterizing scales of sedimentary heterogeneity

2020-11-1  Vertical and lateral variations in channel-deposits proportions were recorded from the lower interval towards the upper one, showing an upwards net-sand content decrease. But also, net-sand content decrease northwards and south-eastwards. This large-scale stratigraphic variation may affect negatively the connectivity of the reservoir.

Sand bars and lagoonal facies occur on top of all sections and are truncated by a sequence boundary. The combined analysis provides insights into the sedimentary processes affecting bottomset and foreset deposition, underscoring the role of wave-influenced hyperpycnal flows, and the effect on organic matter dilution in one of the most important
