Largest and most important podiform chromite deposit in America, with calculated reserves exceeding 5 million tons. The largest chromitite body is 600 m long, 250 m wide, and up to 20 m thick. Tabular to lenticular bodies of chromitite of variable size are crosscut by normal faults. The lenses are invariably parallel to the foliation and lineation of host peridotite and are located in the mantle-crust transition zone, characterized by the interlayering of ultramafic and gabbroic rocks. Dunite (from few centimeters to a few meters in thickness) systematically envelopes the chromitite bodies, though chromitite-harzburgite contacts are locally developed. The contact between chromitite and peridotites is generally sharp and only locally gradational.

Located within the World Heritage listed Alejandro de Humbolt National Park.
