SPATIAL DISTRIBUTION, SIZE AND CHEMISTRY OF GARNET IN A HORNFELS FROM THE TAKATO AREA, RYOKE METAMORPHIC BELT, CENTRAL JAPAN

Abstract

The investigated garnets from a hornfels are small in number and large in grain size. They nucleated at preferred sites which distributed at random. Centers of garnet crystals are very similar in composition with each other regardless of crystal size. This indicates that all the garnets nucleated instantaneously.
