摘　　要：据岩石、矿物组合,首先将地层划分为阳干山岩组绿片岩相带和阴干山岩组绿片-蓝片岩相带;通过地球化学方法,对阿克苏群蓝片岩进行分析,确定绿片岩相带原岩为碎屑岩,蓝片岩相带原岩以基性玄武岩为主,含少量砂岩类碎屑岩。为后期研究相同岩石提供基础地质资料。Based on the method of rock mineral assemblage,the strata are first divided into Yangganshanite formation greenschist facies zone and Yinganshanite formation greenschist-blueschist facies zone.Based on the analysis of blueschist in Aksu Group by geochemical method,the protolith of greenschist facies zone is clastic,and blueschist facies zone protolith is mainly basic basalt with a small amount of sandstone clastic rocks.To provide basic geological data for later rocks of the same origin.
