Genesis of sulfide-rich chromite ores by the interaction between chromitite and pegmatitic olivine-norite dikes in the Potosí Mine (Moa-Baracoa ophiolitic massif, eastern Cuba) Abstract The Potosí Mine is located in the Moa-Baracoa massif in the easternmost part of the Cuban Ophiolitic Belt. Chromite mineralization occurs within the mantle–crust transition zone. Two events of magma intrusion…read more
Uvarovite in podiform chromitites: the Moa-Baracoa ophiolitic massif, Cuba Abstract The chromitite pods of the Moa-Baracoa massif, in the eastern ophiolitic belt of Cuba, contain pre-existing gabbro sills. This association is affected by two processes of hydrothermal alteration. The chromitites and the hosting dunites and harzburgites are affected first by regional serpentinization; a second alteration,…read more
