Mineral Deposits and Global Tectonic Settings



This book aims to show how ore deposits are related to the concept of plate tectonics; it succeeds. Not too long ago, opaque minerals in a thin section were called “ore” by petrologists and then ignored, and ore deposits were freaks of nature which tended to be where you found them. Today, “ore” and ore deposits have become part of mainstream geologic studies—opaque minerals can reveal much about the evolution of a rock, and mineral deposits can reveal tectonic settings.

The main value of this book to most AGU members is that it shows how ore deposits can reveal tectonic setting; ambiguously in many cases, to be sure, but a pattern is emerging. Mitchell and Garson do not stress the flip side, the application of plate tectonics to exploration, although applications are apparent, and a short chapter is devoted to this aspect.
