Huincul Fault
Fault that extends from the Neuquén Basin eastwards into the Argentine Shelf
The Huincul Fault or Huincul Fault Zone (Spanish: Falla de Huincul, Zona de falla Huincul) is an east-to-west-oriented, continental-scale fault that extends from the Neuquén Basin eastwards into the Argentine Shelf.[1] To the west, it has been proposed to extend across the Andes to the Chilean Coast Range.[2]
In the Neuquén Basin, the fault exhibits a slightly curved path, being convex to the north.[3] It is a major geological discontinuity and it truncates the north-to-south-oriented Pampean orogen, among other structures. Because of this, it has been proposed to represent the northern geological limit of Patagonia.[1]
