摘　　要： 本文详细研究了柯树背岩体的岩石学及副矿物学特征 ,研究发现F9大断裂以西部分 (西体 )与F9大断裂以东部分(东体 )在岩性、矿物组成、副矿物特征、锆石群型特征上存在很大差别 ,副矿物特征、锆石群型特征指示东体与寨背岩体类似 ,为同熔系列花岗岩 ;西体为重熔再生岩浆成因的改造型花岗岩。这一认识对于该区的铀金找矿具有一定的指导意义。 In this paper,mineralogical,petrological and accessory mineral characteristics of the Keshubei rock mass,as well as features of zircon groups have been studied in detail.The result shows that the western part of the rock mass differs obviously from the eastern part of the rock mass in mineral compositions,rock types,accessory minerals and zircon groups.The eastern part of the rock mass is similar to the Zhaibei rock mass,being regarded as granite of the syntectic series,whereas the western part of the rock mass is regarded as granite of the reformation series.This opinion has great guiding significance in looking for U and Au mineral deposits in this region.
