摘要: 依据1/50万重力资料,计算了塔里木盆地东南部及阿尔金地区莫霍界面的起伏深度,得出该区地壳厚度展布特征。根据横穿阿尔金山脉的大地电磁测深剖面所提供的岩石圈深部电性结构及研究成果,分析和探讨了塔里木盆地东南部与阿尔金隆起之间的深部构造关系。

Abstract: According to 1: 500 000 gravity data, the Moho-discontinuity depth is calculated, resulting in knowldge of the distribution of crustal thickness in southeastern Tarim basin and Altun area. The relations between deep structures in southeastern Tarim basin and Altun uplift are discussed based on geological structure of deeper lithosphere from magnetotelluric depth (MT) section across Altun mountain.

Key words: Tarim basin, Altun mountain, Bouguer anomaly, Moho-discontinuity, Magnetotelluric exploration, Geological structure
