The role of black shales as a source of sulfur and semimetals in magmatic nickel-copper deposits: Example from the Partridge River Intrusion, Duluth Complex, Minnesota, USA
We examine interactions between black shale xenoliths and mafic magma. Sulfide droplets are entrained in the xenolith melt and transferred to the magma. Sulfur and semimetals contamination of the mafic magma is shown and modeled.
