摘要
利用卫星遥感影像对青海省德尔尼铜矿区的区域地质做了判释性研究 :( 1)判释出 3条左旋平移断层及一组羽式构造 ,并测得其中一条断层的左旋平移距离为 12 50m ,而在以往 1∶2 0万和 1∶5万的地质填图中均未发现这 3条断层的平移性质 ;( 2 )判释出作为蛇绿岩组成部分的地幔橄榄岩呈现与一般岩浆岩不同的影像特征。
An interpretative study of the regional geology of the Dur'ngoi copper district, Qinghai Province, has been conducted using satellite remote sensing images. (1) Three sinistral strike slip faults and a set of plume structure have been interpreted, and one of the faults has been measured to have a displacement of sinistral strike slip of 1 200 m. The strike slip nature of the three faults was not found in the previous 1∶200 000 and 1∶50 000 geological mapping. (2) Pyrolite that is interpreted as a component part of ophiolite exhibits image features that are different from those of ordinary magmatic rocks.
