Abstract
The temperatures of crystallization of 23 calcitic carbonatites have been estimated on the basis of the amount of MgCO3 going into solid solution with calcite. Majority of the carbonatites have a temperature of crystallization between 350° to 475° C., while the one at Sevattur shows a rather high temperature of crystallization (about 600° C). There is a distinct relation between grain size and temperature of crystallization for the Amba Dongar carbonatites.Downloads
