Abstract

Cites recent evidence from investigations of the geochemistry and mineralogy of platinum-bearing deposits in Siberia and South Africa which indicates that platinum-group metals are not necessarily products of early crystallization from basic magmas, but in some cases may have been deposited at much lower temperatures than was formerly considered possible.In addition, processes other than simple crystallization differentiation of sulfide and silicate melts may have been involved.
