Abstract

A Fe and Mn heterogeneity effect was observed in microscopic garnet inclusion in diamond using micro-PIXE. Results are presented and the implications of these disequilibrium element distributions during growth of garnets are discussed. The occurrence of zoning or any type of chemical inhomogeneity within inclusions encapsulated within diamond has implications on the age of formation of the inclusion and the diamond. It is believed that the age of the inclusion is that of the diamond formation itself, with subsequent isolation of the inclusion from the mantle by the diamond. The significance of the chemical heterogeneity or zoning is that it should not exist given the high temperature and long time of encapsulation.
