A Note on the Origin of Chrome Grossular Garnet (Uvarovite) in Calc-Silicate from Bandihalli, Tumkur District, Karnataka
Subscribe/Renew Journal
The green garnets found in the calc-silicate horizons around Bandihalli, is a chrome grossular (∼7% Cr2O3) with appreciable amount of Mn content. Thus, a partial miscibility between uvarovite and spessartite end members appears possible. The occurrence of thin band of graphite bearing quartzite within the calc-silicate horizons points to its metasedimentary origin. The presence of another variety of garnet (pyrope-almandine rich) in the associated cordierite bearing rock of the area shows that the composition of garnet may not be wholly dependant on grade of metamorphism.
