San Rafael orogeny

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]

Some of the plutons of the Elqui-Limarí Batholith were emplaced a context of crustal thickening derivative of the San Rafael orogeny.[2]
