Homblendes and their host rock amphibolites from amphibolite facies and hornblende-granulite sub-facies were analysed for major elements. The hornblendes show small changes in chemistry which are related to host rock compositional changes rather than the pressure and temperatures condition of formation.

Abstract


Homblendes and their host rock amphibolites from amphibolite facies and hornblende-granulite sub-facies were analysed for major elements. The hornblendes show small changes in chemistry which are related to host rock compositional changes rather than the pressure and temperatures condition of formation.
