Geology, mineralogy and geochemistry of the Cerro Matoso nickeliferous laterite, Córdoba, Colombia
The Cerro Matoso nickeliferous laterite, located in northern Colombia near the town of Montelibano, was developed in pre-Late Cretaceous ultramafic rocks consisting principally of slightly serpentinized harzburgite. The peridotite body is flanked by ferruginous sandy sediments with interbedded coal beds of the Cienaga de Oro Formation (early Oligocene-early Miocene) and Recent alluvial gravels and sands. The harzburgite consists predominantly of olivine with lesser amounts of orthopyroxene and secondary serpentine. Intense serpentinization is primarily confined to areas of faulting and brecciation ...
