Kolah Ghazi Granodiorites Enclaves of south Isfahan
Different type of enclaves are found I n Kolah —Ghazi granitic rocks The microgranolar enclaves MGE are generally lime
granied rounded and have mineralogical charactaistic these of the host granite two type of MGL are present The mafic (MMI)and the lilsic microgranolar( FME) enclave the FME arc liner then their host granite and are prohebly crystallized pieces ol Kolah Ghazi granodiorite that have been re incorporated into the magma
The MME are mainly composed of plasioclase and mafie mineral. The mineralogical Composition of the MME are indicate thate thise enclaves and their host were in equilibrium when the mafic minerals crystallized. The surmicaceous enclavesare en riched in biotite and in cordierite Garnet( rare). AL —silscates.
