物化探工作在崇义东峰矿区的应用及找矿效果

摘要

The Dongfeng tungsten deposit is located in the Chong-Yu-You metallogenic prospect area , where is suited in the eastern Nanling Tungsten-tin Poly-metallic Metallogenic belt. With the use of geochemical and geophysical exploration, anomaly areas were delineated by inferring the shape of buried rock body. Then, the deep holes were drilled to verity the new mineralized zone in the anomaly areas delineated before. This paper elaborated the prospecting process of tungsten deposit and results. And the pratice shows that it can improve the efficiency of geological prospecting by the properly use of the method which is the geochemical and geophysical exploration in advance and associating with the surface comfirmation and drillings verification.%崇义东峰钨矿位于南岭东部钨锡多金属成矿带崇义—大余—上犹矿集区内，北邻淘锡坑钨矿。结合近年在矿区开展的以钨为主的矿产远景调查评价工作，通过化探工作圈定出异常区11处，应用物探音频大地电磁测深（AMT）工作推测矿区隐伏岩体形态，再对最优异常区进行异常查证，发现了矿化标志带，再投入槽探揭露、深部钻孔验证，找到了隐伏的钨多金属矿带。详细阐述了在东峰矿区寻找钨矿的过程及找矿效果，实践证明物化先行、地表查证和钻探验证相结合的方法，有较好的找矿效果。
