【摘要】 通过对砂岩碎屑组分组成特征、重矿物组合及其稳定系数、重矿物ZTR指数以及地震剖面等方面资料的分析,认为研究区克拉玛依组为东部和北部两大物源所控制且离物源较近。三台地区的物源在其东部,母岩类型以中性、基性岩浆岩为主;而北三台地区的物源在其北部,母岩类型以中性、基性岩浆岩和变质岩为主。更多还原

【Abstract】 After the analysis of characteristics of clastic composition in sandst one,heavy minerals combination and their coefficient of stability,ZTR maturity index and seismic profiles.It is concluded that Karamay Formation was controll ed by eastern and northern sedimentary sources,and was close to its source area.The sedimentary source of Santai area lies to its west direction,where the mo ther rock is neutral-basic igneous rock mainly.The sedimentary source of Beisan tai area is to its north direction,where the mother rock is mainly neutral-basi c igneous rock and metamorphic rock.更多还原
