Type Complex Country Chile Region Atacama Region | Other Greenschist Named for Punta de Choros Primary Schist | |
The Punta de Choros Metamorphic Complex or PCMC is a large coherent group of metamorphic rocks –in other words a geologic complex– of the Chilean Coast Range in northern Chile. It consists mainly in micaschists, greenschists and other low-grade metasediment. The complex was formed by subduction metamorphism of sediments and mafic rocks at the interface between a subducting plate and the overriding plate.
The complex owes its name to Punta de Choros.
