The Rocas Verdes ophiolites (Spanish: Complejo Ofiolítico de Rocas Verdes) are a series of greenschists and other rocks constituting ophiolites in Magallanes Region, southernmost Chile.
The Rocas Verdes ophiolites represent the continental-oceanic crust that existed in a back-arc basin in the Mesozoic Era as result of extensional tectonics.
[1] This back-arc basin then evolved into the Magallanes foreland basin in the Cenozoic Era within the context of the wider Andean orogeny.
[1] The main Rocas Verdes ophiolites are the Sarmiento and Tortuga complexes.
Volcanic rocks in both complexes belong to the tholeiitic magma series.
