Huincul Formation
The Huincul Formation is a geologic formation of Early Cretaceous (Albian) age of the Neuquén Basin that outcrops in the Mendoza, Río Negro and Neuquén Provinces of northern Patagonia, Argentina. It is the second formation in the Río Limay Subgroup, the oldest subgroup within the Neuquén Group. Formerly, that subgroup was treated as a formation, and the Huincul Formation was known as the Huincul Member.
