山西王官屯地区遥感环形构造成因及其找矿意义

Cause of Remote Sensing Ring Tectonic and Prospecting Significance in Wangguantun Area of Shanxi Province

环形构造代表构造岩浆的有利部位,是遥感找矿解译研究的主要内容之一。一般情况下,花岗岩类侵入体和火山机构引起的环形影像时代愈新,标志愈明显。通过对王官屯地区泉子沟环形构造、堡子湾-牛马河环形构造和镇边堡环形构造三个主要环形构造的影像特征及其成因的剖析,初步探讨环形构造对于矿产资源勘查的意义,在深入分析的基础上,提出了充分利用卫星遥感影像环形构造特征信息结合区域地质特征来为找矿工作提供指示的思路。

The ring structure represents the favorable position of tectonic-magma,which is one of the main contents of remote sensing ore-prospecting interpretation.In general,the more recent the ring images caused by granitic intrusions and volcanic mechanisms are,the more obvious the signs are.By analyzing the image features and causes of the three main ring structures,namely,quangzigou ring structure,baoziwan-niumahe ring structure and zhenbianpu ring structurein in wangguantun district,and discussed the significance of ring structures to mineral resources exploration,on the basis of the thorough analysis,proposed the full use of satellite remote sensing image ring structure characteristic information combined with regional geological features to provide instructions for ore-prospecting work.
