摘　　要：西藏1∶50000古木加康地区区域地质调查首次采用洋板块地层(结合带)构造-岩石地层填图方法对地层进行划分;进行了大量锆石U-Pb测年,划分出了寒武纪、晚三叠世、白垩纪以及始新世四期岩浆活动;大致划分了三个变形期次、三个变形亚带;对测区构造进行了深入详细的解析,划分了三个构造期次,五个构造单元,建立了构造格架。1:50,000 regional geological survey in the Gumujiakang area,Tibet is carried out by mapping method of tectonic-lithostratigraphy for oceanic plate strata(joint zone).Four magmatic activity periods such as Cambrian,Late Triassic,Cretaceous and Eocene,three deformation stages are divided by a large amount of zircon U-Pb dating data.Three deformed zones are divided.Three tectonic periods and five tectonic units are divided.The tectonic framework is established in this region.
