    庐枞盆地东北部马鞭山—黄屯—鹤毛河地区地球物理特征及找矿预测

    Geophysical characteristics and prospecting prediction of the Mabianshan-Huangtun-Hemaohe area in the northeastern Luzong basin

    • 摘要: 马鞭山—黄屯—鹤毛河地区位于庐枞火山盆地东北部,深部岩浆活动频繁。在该区开展了高精度磁法勘探和可控源音频大地电磁测深(Controlled Source Audio Magnetotellurics,CSAMT),查明深部岩体及构造展布情况,进一步预测找矿靶区。为了评价地球物理勘探成果的可靠性,在推测断层FT1和FT2的复合部位进行钻探追索,在ZK18-1钻孔100~250 m深部发现金铜矿体; 在勘探18线设计ZK18-2钻孔,进一步圈定金铜矿体范围,扩大找矿成果。

       

      Abstract: Mabianshan-Huangtun-Hemaohe area, which is located in the northeastern part of the Luzong(Lujiang-Zongyang)volcanic basin, experiences frequent magmatic activities at the depth. High-precision Magnetic and Controlled Source Audio Magnetotellurics(CSAMT)method was carried out in the area to identify deep rocks and structural distribution for further predicting target areas in the study area. In order to evaluate the reliability of geophysical exploration results, drilling was performed in the composite parts of fault FT1 and FT2, revealing gold-copper orebodies at depth of 100~250 meters around borehole(ZK18-1)and delineating the scope of gold and copper orebodies. This practice further increases prospecting results.
