Abstract

EPMA analyses of uvarovite from the chromite-bearing ultramafic intrusive of Sukinda, India, show that uvarovite containing 9.83 to 17.68 wt% Cr2O3 represents a solid solution of the binary uvarovite-andradite series with Uva34-58 And42-58 . Associated chromite grains with 57-59 wt% Cr2O3 do not show any compositional variation from core to rim. 57Fe Mössbauer spectroscopic studies on the uvarovite samples undertaken both at room temperature (298 K) and low temperature (110 K) indicate the presence of Fe3+ only in octahedral coordination. Uvarovite grew from chromite (Cr source) and pyroxenes (Al, Fe, and Ca source) of the ultramafic host rocks.
