Abstract

The rising of magmas through calc-alkaline volcanosedimentary piles, by magmatic stoping and assimilation processes, is characteristic of the Andinotype and island-arc orogenic environments. They also have a typical association of ore deposits in which porphyry copper and volcanogenic ore deposits are dominant. This paper discusses their geological-metallogenetic relationships, from the viewpoint of the syngenetic-epigenetic and consanguineous-foreign categories. The discussion is illustrated by two examples from the Chilean metallogenetic province: the “manto” type copper deposits and the magnetite deposits of Cretaceous age (“Franja Principal”, Ruiz 1965).
