| 摘 要： | 本文根据帕米尔地区（32°N-42°N,66°E-80°E）的重力资料,计算出深部重力场。以费尔干纳-帕米尔-斯利那加地震测深剖面数据作为控制与参考资料,采用三维横向变密度重力模型,进行重力反演计算,求得研究区莫霍界面的起伏深度,并依此给出研究区的地壳厚度分布特征。结合帕米尔及其周围地区的地震活动和均衡异常,对这一地区的构造运动进行了初步探讨。

| Abstract: | The deep gravity field in the area （32°N-42°N,66°E-80°E） has been obtained through calculation on the gravity data observed there.Meanwhile,Moho discontinuity and crust thickness have also been obtained through gravity inversed computation on the 3-D models of the horizontal changing densities,using as reference the data of the seismic sounding section of the Fergana-Pamir-Srinagar area.Based on this,a map of the crust thickness of this area has been drawn as well.Furthermore,taking into consideration the seismic activities and isostatic anomalies in the area,an analytical study of the plate motion on the Pamir and Central Asian region has been made. |
