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.

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.
