Abstract

In this paper computer program THERMOCALC, GIBBS and THERIAK-DOMINO are discussed and pseudosections are generated on some chemical data taken from the published literature from the Himalaya and Alps and also new chemical and EPMA data generated from the Garhwal Himalaya to demonstrate the capabilities of THERMOCALC and THERIAK-DOMINO. Usefulness and limitations of computed pseudosections (equilibrium assemblage diagrams) with THERIAK-DOMINO and THERMOCALC in understanding evolutionary history of metamorphic rocks are discussed
