2008 Annual Report

Microphotograph (X Nicols) of an olivine xenocrist embedded in a diorite matrix consisting of plagioclase, clinopyroxene, amphibole, biotite and quartz. The olivine grain is surrounded by a small corona of orthopyroxene. The change in interference colors from core to rim is related with an increase in fayalite component in olivine.
