Huincul Fault
[2] In the Neuquén Basin, the fault exhibits a slightly curved path, being convex to the north.[4] The main stress vector (i.e. direction of compression) was originally northwest-oriented but shifted over time to the north-northwest.In the Late Miocene, the last phase of deformation began with east–west compression followed by tectonic extension in Pliocene times.[4][5] The basement high is one of the most studied features of the Neuquén Basin, given its importance for hydrocarbon exploration and production.In this region, a series of basement highs and small pull-apart basins has formed along the fault, reflecting a clockwise movement.
