西藏阿里地区夏康坚雪山构造地貌特征及其形成机制

Tectonic landform characteristics and formation mechanism of Xiakangjian jokul in Tibet, China

简述了冈底斯构造带夏康坚地垒断块山的组成及基本构造特征。根据该地垒两侧冰碛阶地的发育特征及ESR测年结果,可推断该地垒的主要形成期是中更新世。夏康坚地垒断块山的成因是在白垩纪早期的古隆起基础上,东西向断层的右行剪切走滑和隆升活动的联合作用下而形成。

The paper describes the composition and the structural feature of the Xiakangjian blockgebirge. According to the moraine terrace and the ESR age of the moraine on the two sides of the Xiakangjian blockgebirge, it can be considered that the formation time of the Xiakangjian blockgebirge is Mid-Pleistocene. The cause of formation is the compounding action of strike-slip and raising.
