Abstract

Cerro Negro is a relatively isolated topographic eminence situated at Northeast of the Patia river basin, whose lithology suggests the presence of a shallow intrusion, which probably presented an effusive phase. The tectonic, structural and petrographic characteristics suggest the occurrence of phreato-magmatic explosions, followed by magmatic injection, with the subsequent formation of a diatrem. The mineral occurrences in the mentioned mountain, are related to that phenomenon.
