... & Fleet 1989 ). Uvarovitic garnet typically contains significant amounts of grossular and andradite components and is commonly interpreted to have formed from chromite (Cr-rich spinel) by metasomatic reaction ( Challis et al . 1995 ). However, conditions for the metamorphic evolution of chromian spinel...
