The San Rafael orogeny was an
orogeny that affected parts of western
Argentina and Chile during the
Late Paleozoic. The resulting orogenic belt has a NW-NNW curved form.[1] The San Rafael orogeny might have been linked with the roughly contemporary
Gondwanide orogeny of eastern Argentina. Parts of the
Choiyoi Group sediments were deformed by the San Rafael orogeny.[2] During the
Neogene ancient faults related to the San Rafael orogeny conditioned the geometry of the blocks affected by the
Andean orogeny.[1]
