C.S. Li, A.J. Naldrett, E.M. RipleyCritical factors for the formation of a nickel-copper deposit in an evolved magma system: lessons from a comparison of the Pants Lake and Voisey’s Bay sulfide occurrences in Labrador, CanadaCited by: element (PGE) deposits in Sudbury has resulted in a marked shift in exploration focus in Canada’s world-class mining camp. Traditional exploration methods in the Sudbury basin have recently been challenged in the quest for new Footwall-hosted vein-style Cu-PGE (ie. Nickel Rim South, Levack Footwall) and Low-sulfide high PGE resources (ie. PGE Studies in the Footwall at Sudbury By C. Li and A.J.

PGE studies in the footwall at Sudbury, Ontario geoscience.   Extensive studies of the fractionation of precious metals between contact and footwall mineral zones have been presented in Naldrett et al. (b, ). A detailed study of Strathcona illustrates the differences that exist between contact, transitional, and footwall mineral zones from representative sampling of this portion of the Levack.

J. Naldrett, Allan Wilson, Judith concluded from their trace element study of the Merensky Reef and adjacent rocks in four boreholes in the southwestern Bushveld that these strata were the result of different degrees of mixing or mingling of A lateral mixing model for the genesis of the Merensky Reef. PGE-enriched Critical Zone (U Cited by: There are four critical phases in the formation of magmatic Fe-Ni-Cu ± platinum-group element (PGE) sulfide deposits (Naldrett, a, b, ): (1) a metal-bearing, mafic or ultramafic parental magma forms by partial melting of the mantle, separates from the solid residue, ascends through the asthenospheric and lithospheric mantle, and intrudes into the crust or erupts on the surface; (2.

Shaffer Parkway Littleton, CO ISBN: Cited by:   The Amy Lake PGE zone is a “low-sulfide-type” Cu-(Ni-)PGE mineralization in the East Range footwall of the Ga Sudbury Igneous Complex occurring in a m-wide Sudbury Breccia belt that coincides with an impact-related major fracture zone (Bay Fault zone).

The labels next to the experimental data are explained in by: M agmatic nickel-copper-PGE sulfide deposits form as the result of the segregation and concentration of droplets of liquid sulfide from mafic or ultramafic magma and the partitioning of chalcophile elements into these from the silicate magma. While a wide range of base, precious, and semimetals are recovered from them, the most important products are Ni and Pt. in Figure 1 the cash price for.
