COPEDIM is an International Joint Laboratory about "Copper and Pediment"

COPEDIM is an international research group in geosciences (Geomorphology, Geology and Geochemistry) focusing on the development of geological erosion surfaces (called pediments) in the Andes and on associated supergene concentration of some metals like copper.

How and when did erosion and weathering surfaces develop in mountain ranges is a crucial issue  to reconstruct  climatic and tectonic changes through geological times. Understanding the possible link with supergene mineralization has economic implications. 

This network has been initiated by the Institut de Recherche pour le Développement (IRD). It has the structure of a "virtual laboratory", with directors, scientific comity, researchers and technicians belonging to different chilean, peruvian, canadian and french institutions. It is supported by these institutions and industry. Its center of gravity is located at UCN, Antofagasta.
