COPEDIM (COPPER PEDIMENT) (Dir. S.Carretier and R. Riquelme)


COPEDIM est un Laboratoire Mixte International (LMI) de l'IRD. Il implique le laboratoire Géosciences Environnement Toulouse, l'Universidad Catolica del Norte (Antofagasta Chili), l'Universidad de Chile (Santiago Chili), l'INGEMMET (Lima Peru) et l'Universidad Nacional de Ingeneria (Lima Pérou). Ce laboratoire vise à mieux comprendre les processus d'applanissement des chaînes de montagne et la  minéralisation conjointe de cuivre et autres métaux au sein des grandes surfaces d'érosion (pédiments). Les sites d'études sont au Chili et au Pérou. L'originalité de COPEDIM est de fédérer des géomorphologues, structuralistes et géochimistes pour aborder des questions à la fois fondamentales (rôles des variations du climat, de l'altération, processus d'érosion, géodynamique) et appliquées (guide géomorphologique pour l'exploration).

COPEDIM is an  International Joint Laboratory  (LMI) of IRD. It involves the laboratory Géosciences Environnement Toulouse (France), the Universidad Catolica del Norte (Antofagasta, Chile), Universidad de Chile (Santiago Chile), INGEMMET Lima (Peru) and the Universidad Nacional de Ingeneria Lima (Peru). This laboratory aims at better understanding the process leading to flattening the mountain ranges and the associated mineralization of copper and other metals within major erosion surfaces (pediments). Study sites are  in Chile and Peru. The originality of COPEDIM is to federate  geomorphologists, geochemists and structuralist in order to address issues both fundamental (roles of changes in climate, weathering, erosion, geodynamics) and applied (geomorphological guide for exploration).
