Abstract:   (718 Views)

The chemical composition of amphiboles from granitoid rocks of Selijerd and Neshveh plutons in NW Saveh, Central Iran, are studied for petrogenetic purpuses, tectonomagmatic features and geotermobarometery of these plutons. The chemical composition of these amphiboles falls in the calcic amphibole group and is actinolite to magnasio-hornblende. They are assosiated with the active continental margin subduction-related zone and formed in relatively high oxygen fugacity. Based on the geotermobarometeric methods, amphiboles from these plutons formed in temperatures ranging from 700 to 750 ° C and low pressures ranging from 0.3 to 1.2 kilobars equivalent to a depth of approximately 1 to 4.5 km, respectively.
