Nickel Deposits of USGS

Nickel Deposits of USGS

nickel ore deposits are closely associated with mafic and ultramafic in trusive rocks, and the nickel in the ore bodies was probably derived either from the intrusives themselves or from similar rocks at depth. Thus the original source of most of the nickel ore bodies found in North America and elsewhere in the world was probably the mantle.
