Merensky Reef Wikipedia

The Merensky Reef is similar to the Platreef because of the presence of primitive mantle, layered intrusions and levels of nickel and copper. The Merensky-type reef has been separated into two categories, the orthomagmatic and the hydromagmatic. The orthomagmatic group is composed of platinum group element mineralization.
