Garnet is one of the most common minerals observed in a variety of rocks.
Large epithermal Au-Ag and porphyry Cu-Au-PGM deposits occur in K-rich alkaline igneous rocks (shoshonites) in many parts of the circum-Pacific and circum- Mediterranean.
We have studied a composite, 16x11x5 cm sized garnet pyroxenite xenolith with three petrographically and compositionally distinct layers (Type II after MacGregor
The Ti content of zircon and the Zr content of rutile have been shown to give a direct indication of the temperature of crystallization and metamorphic growth respectively, resu
