And apatite. by these analyses and comparison with general granite both in china and the world and with the granite in other au or cu belt in china, the characteristics of the granite in this area are concluded as follows. it belongs to magnetite - i or syntectic granite and has crust - mantle mixed characteristics ; it was formed mainly by crystallization differentiation of melting magma and multiphase varied intrusion ; the degree of differentiation evolvement is not high ; the granite and its enclaves p. re congenetic ; the range of temperature is about 500 - 700, the range of pressure is about 2. 50 gpa - 4. 35 gpa, and the range of oxygen fugacity ( lg fo2 ) is - 15. 53 - - 14. 00 ; most granite bodies formed before the collision of plates, and few formed after the collision of plates
