摘要
湖南临武县铷多金属矿床属于燕山早中期的岩浆岩型矿床,具有全岩矿化和规模大的特征,本文根据高精度磁法测量和激电中梯剖面测量结果,在矿区内初步圈定出7处磁异常和7处激电异常,经过查证后发现异常区在地表具有良好的矿化显示,大多数是矿致异常,总体上地球物理找矿方法在该矿床的应用中取得了良好的应用成效。因此,在今后的找矿勘查中,应加强地表矿化与磁异常、激电异常吻合区域深部的钻孔验证工作,进一步扩大该区域的资源储量。
The rubidium polymetallic deposit in Linwu County,Hunan Province belongs to the magmatic rock type deposit in the early and middle period of Yanshan,with the characteristics of all-rock mineralization and large scale,according to the high-precision magnetic measurement and excitation ladder profile measurement results,7 magnetic anomalies and 7 excitation anomalies were initially delineated in the mining area,and after verification,it was found that the anomaly area had a good mineralization display on the surface.Most of them are ore-induced anomalies,and overall,geophysical prospecting methods have achieved good application results in the application of this deposit.Therefore,in the future prospecting exploration,the drilling verification work in the deep part of the area where surface mineralization coincides with magnetic anomalies and excitation anomalies should be strengthened,and the resource reserves of the region should be further expanded.
