Contaminated Granites

Volume 45, Part 1, 2007
Editors : B. Clarke, S. Paterson, R. Vernon, R. F. Martin

This issue of The Canadian Mineralogist presents a thematic set of papers on Contaminated Granites edited by Barrie Clarke, Scott Paterson, and Ron Vernon.

Petrogenetic investigations should always consider granites not so much as the products of crystallization of pristine melts, but as mixtures of such melts and a variety of other components (solid, liquid, vapour) that have contaminated them. Only when we can confidently determine the magnitude of contamination, and are able to subtract its effects, will we be able to understand what the granite magma itself has to say.
