摘要
内蒙古达茂旗哈力齐金矿是新近发现的中-低温热液石英脉-蚀变岩型金矿点,位于华北板块北缘增生带乌德岩浆构造混杂带北侧,矿体呈脉状产于下泥盆统查干合布组二云母板岩-浅变质石英砂岩中。通过对成矿地质背景和矿床地质特征分析,认为矿点受近东西向深大断裂的次级断裂构造控制明显。在成矿条件分析的基础上,结合分量化探测量、高精度磁法和音频大地电磁测量(AMT)等综合信息,认为在已发现金矿化石英脉的深部和两侧具有很好的找矿潜力。
Haliqi gold deposit is an epithermal quartz-vein type gold deposit which has been found in the second- ary fracture of the Wude tectonic m61ange belt. The deposit occurred in the epimetamorphic quartzose and mi- ca-slate of lower Devonian Chaganhebu Formation and was controlled by the nearly EW-trending deep faults. On the base of analysing the mineralization geological setting and metallogenic conditions, we use controlled-source audio-frequency magnetotelluric method, high-precision magnetic survey method and partial content geochemi- cal survey method to forecast the gold metallogenetic potentiality. It is suggested that the ends and deep part of the mineralized quartz veins are an important metallogenic prospective area.
