GARNIERITE: LATERITIC GREEN NICKEL "MINERAL"

Jul 08, 2014· GARNIERITE: LATERITIC GREEN NICKEL "MINERAL". The Sudbury nickel is found in a typical pyrrhotitepentlandite massive sulfide ore that is of mantle origin associated with an intrusive event. The impact force of the meteorite caused wholesale melting of the mantle, triggered the huge intrusion, and emplaced the nickel deposit (Stefano, 2014,...
