Deposit Characteristics and Prospecting of Haliqi Gold Deposit in Damaoqi, Inner Mongolia

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.

Abstract: Haliqi gold deposit is an epithermal quartz-vein type gold deposit which has been found in the second-ary fracture of the Wude tectonic mélange 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.-
