Subject Index


Developments in Geochemistry, Volume 2: Rare Earth Element Geochemistry presents the remarkable developments in the chemistry and geochemistry of the rare earth elements. This book discusses the analytical techniques and the recognition that rare earth fractionation occurs naturally in different ways.

Organized into 13 chapters, this volume begins with an overview of the wide array of types and sizes of the cation coordination polyhedral in rock-forming minerals. This text then examines the application of rare earth element abundances to petrogenetic problems that has centered on the evolution of igneous rocks. Other chapters consider the matching of observed rare earth element abundances with those provided by the theoretical modeling of petrogenetic processes. This book discusses as well the hypotheses on the genesis of a rock or mineral suite. The final chapter deals with the principal analytical methods.

This book is a valuable resource for undergraduates, lecturers, and researchers who study petrology and geochemistry.
