Summary and use of genetic concepts in exploration

Abstract

The magmatic model for the formation of magmatic sulfide deposits carries with it concepts that have many implications for exploration-some simple, qualitative, and in common use and others not so simple, more quantitative, and not yet in common use. Examples of the application of these concepts form the subject ofmuch oftbis chapter. PGE deposits have different characteristics, and bring, with them different criteria for recognizing likely ore-bearing environments. In order to avoid confusion, Ni-Cu deposits are discussed first, followed by a discussion of PGE deposits.
