Abstract
A fluid-rock interaction model for treating the stable carbon and oxygen is otopic variations in altered carbonatites is presented and illustrated with an example using data from the ferrocarbonatites of Amba Dongar, Gujarat. The Amba Dongar ferrocarbonatites appear to have been altered by a fluid of magmatic origin at 100 to 200 degrees C contrary to an earlier suggestion of meteoric groundwater alteration at similar to 50 degrees C.
