摘　　要：阿尔金造山带地质情况复杂,各类岩石地层呈大小差异悬殊的构造岩片或岩块产出,岩石地层单位厘定争议已久。根据前人统计的资料及1∶5万区域地质矿产调查,对原划分于阿尔金岩群中,但岩石类型及其组合、变质程度、原岩建造特征和变质矿物组合等方面,与阿尔金岩群定义不符的岩石组合经过区域对比,结合测年数据,将其厘定为巴什库尔干岩群贝壳滩岩组,并分析其具有Cu、Mo找矿前景。The geological conditions of the Altai orogenic belt are complex,and various rock formations are produced as structural rock fragments or blocks with significant differences in size.The determination of rock stratigraphic units has been controversial for a long time.Based on previous data and a 1∶50000 regional geological and mineral survey,rock combinations that were originally classified in the Altun Group but did not match the definition of the Altun Group in terms of rock type and combination,metamorphic degree,original rock construction characteristics,and metamorphic mineral combination were compared in the region,and combined with dating data,they were determined as the Beike Beach Formation of the Bashkorgan Rock Group.
