  4. 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
    通过对测试数据的分析与综合研究,并同中国和世界一般花岗岩类以及中国主要金、铜成矿岩体的花岗岩类进行对比,得出本区花岗岩类岩石具有以下特征:属磁铁矿-型或同熔型花岗岩,其岩浆物质具壳幔混源特征:主要由熔融态岩浆经结晶分异作用,通过多期变速上侵而形成;其分异演化程度较低;寄主岩基和包体具有同源性;岩石的形成温度范围约为500 - 700 ,压力大约为2 . 50gpa - 4 . 35gpa ,氧逸度值1gfo _ 2为- 15 . 53 ? 14 . 00 ;该岩带主要形成于板块碰撞前消减的活动板块边缘期,为燕山至喜马拉雅早期的大陆边缘火山弧环境的产物。
