Ore-body mapping, shows several zones, whose boundaries are gradual and the garnet color is controlled by the distance up to intrusive contact: the first zone corresponds to a fresh tonalite-cuarzodiorite, the second one corresponds to the endoskarn, the third one corresponds to the exoskarn: a prograde stage, characterized by garnet and pyroxene in lesser extent, and a retrograde stage, with the mineralization (iron oxides, iron and copper sulfides), actinolite-tremolite, euhedral quartz and calcite.
