摘要
安徽省萧县旗杆楼铁矿主要矿种为矽卡岩型磁铁矿。区内以往开展过低精度地磁和航磁工作,并据此验证查明了洪河集、杨套楼工业磁铁矿,然而李口磁异常区找矿效果不理想。为在旗杆楼铁矿深部及外围寻求进一步铁矿找矿突破,开展了密网(50m×20m)控制的、总面积31.37km^(2)的高精度磁测工作,结合区内断层分布、钻孔揭露等地质资料,综合分析认为:李口地区深部(900m以深)具备较好的磁铁矿找矿潜力;洪河集、杨套楼铁矿外围及深部寻求更大突破的潜力较小。本文通过实例验证了高精度磁测指明磁铁矿老矿区找矿方向的有效性,对旗杆楼及相近磁铁矿地区寻求进一步找矿突破意义重大。
The main ore type of Qiganlou iron ore mine in Xiao County,Anhui Province is skarn-type magnetite.Previously,low-precision geomagnetic and aeromagnetic work has been carried out in the area,and industrial magnetite ore in Hongheji and Yangtaolou has been verified and identified,however,the effect of mineral searching in the magnetic anomaly area of Likou is not satisfactory.In order to seek further breakthroughs in the search for iron ore in the deep and periphery of the Qiganlou iron ore mine,a high-precision magnetic survey with a total area of 31.37 km^(2) controlled by a dense network(50 m×20 m)was carried out.Combined with the distribution of faults in the area,the geological data exposed by drilling holes and other information,a comprehensive analysis concludes that the deep part of the Likou area(900 m in depth)has a good potential for magnetite ore search,and the periphery and deep part of the Hongheji and Yangtaolou iron ore mines have less potential to seek greater breakthroughs.The potential of seeking a bigger breakthrough is relatively small.This paper verifies the validity of high-precision magnetic survey to point out the direction of magnetite ore searching for the old mining area through the example,which is of great significance for seeking further breakthroughs in searching for magnetite in Qiganlou area and similar magnetite ore areas.
