Formation of magmatic nickel-sulfide ore deposits and ...

Nickel-copper sulfide ore deposits are found at the base of mafic and ultramafic bodies. All their host rocks, except the Sudbury Igneous Complex, are thought to be mantle derived melts. The Sudbury Igneous Complex is thought to be the product of complete melting of continental crust. In the case of mantle-derived magmas, a high degree of partial melting of the mantle serves to enrich the ...

Magmatic Deposits / Prospecting Guidelines

Magmatic Base Metals Deposits Chrome - Nickel/Copper - Platinum Group Metals (PGM) Magmatic Deposits are so named because they are genetically linked with the evolution of magmas emplaced into the crust (either continental or oceanic) and are spatially found within rock types derived from the crystallization of such magmas.

Platinum Metals Magmatic Sulfide Ores | Science

Platinum-group elements (PGE) are mined predominantly from deposits that have formed by the segregation of molten iron-nickel-copper sulfides from silicate magmas. The absolute concentrations of PGE in sulfides from different deposits vary over a range of five orders of magnitude, whereas those of other chalcophile elements vary by factors of only 2 to 100.
