Maricunga gold belt

Tags: cenozoic paleozoic pliocene

Description:

The Maricunga gold belt extends over a distance of approximately 150 km from north to south and is approximately 30 km wide, close to the border with Argentina. Mineralization is related to the emplacement of Miocene (11-10 Ma and 8-7 Ma) age calc-alkaline volcanic and sub-volcanic units over basement rocks of Paleozoic to Cenozoic age. The Maricunga belt hosts a number of gold and goldcopper (silver) deposits including La Coipa, Maricunga, Aldebaran, La Pepa, Soledad, Pantanillo, Lobo, Escondido and Marte.

The structural setting at OdAE (and the balance of the Volcan Project to the east) is related to, and associated with, the formation of the Copiapo (+200 km2 area) stratovolcano (Volcán Copiapo) and may also be related to regional northerly-trending high angle reverse faulting. Cameco (Czollak, 1992) identified three generally moderate to steeply dipping fault systems, trending northwestsoutheast, northeast-southwest and east-west, and considered the northeast-southwest and east-west trending systems to be the more important structural controls on alteration and mineralization.
