Taitao_ophiolite
Taitao ophiolite (Spanish: Ofiolita de Taitao) is an ophiolite in Taitao Peninsula of western Patagonia, Chile. The ophiolite crops out about 10 km w to the east of the Peru-Chile trench and 50 km to the south of Chile Triple Junction —two features to which it is related.[4][5]
The ophiolite formed in connection to the subduction of the Chile Rise, a mid-ocean ridge, beneath South America.[4] More specifically it has been proposed that the ophiolite formed in a rift of the forearc region of the South American plate.[6]
The Taitao ophiolite presents a pseudostratigraphy with the following lithologies; peridotite, pyroxenite, gabbro, sheeted dykes of diabase, pillow lava and sedimentary rock.[4][5]
