| 中文摘要: |
| 祁门县东源钨钼矿床是安徽省目前探明的规模最大的斑岩型钨矿床,主要矿床类型为斑岩型白钨矿。物探异常对该矿床的发现、勘查具有较为重要的意义。矿区1∶1万磁法测量成果显示,在江家和东源存在两个近椭圆形的、总体呈北东向展布的正异常；而1∶2千综合物探剖面异常对勘探工程的布置起到直接的指导作用。文章着重从区域物探、矿区磁法扫面和物探剖面异常3个方面来阐述物探异常在该矿床勘查过程中的指导意义。 |
| 英文摘要: |
| Dongyuan W-Mo deposits in Qimen is the biggest known porphyry tungsten deposit in Anhui Province with its dominate deposit being porphyry scheelite.Geophysical anomalies have much effects on the discovery and exploration of the deposit.The 1∶10 000 magnetic prospecting results show that there are two nearly ellipses positive anomalies which are northeastward in Jiangjia and Dongyuan(Xiyuan). While the 1∶2 000 comprehensive geophysical anomaly profiles are much more important on the direct guidance of exploration engineering arrangement. This article dominantly expounds geophysical anomalies and its guidance in deposit exploration from three aspects:regional geophysical prospecting, ground magnetic survey and geophysical anomaly profiles. |
