宁夏金场子金矿床关键控矿因素分析及找矿方向

卫宁北山金场子金矿位于构造活动带与稳定地块的过渡转换部位,矿化热液蚀变明显,是宁夏回族自治区金多金属矿最具找矿潜力的地区之一。通过对金场子矿区金多金属成矿关键控矿因素和成矿规律研究,结果表明:东西(EW)向和北东(NE)向构造是该区主要控矿构造;金场子金矿体主要赋存在下石炭统前黑山组、臭牛沟组和上泥盆统中宁组,其成矿物质主要来自地层;位于黄石坡沟-金场子背斜两翼地层中的EW向断裂与NE向断裂交汇部位是该区最佳的找矿部位。

Analysis of key ore-controlling factors and prospecting direction of Jinchangzi gold deposit in Ningxia

Jinchangzi gold deposit in Weining Beishan is located in the transition part between the tectonic active zone and the stable block. The hydrothermal alteration of mineralization is obvious. It is the most potential area for polymetallic ore prospecting in this area. The authors believe that EW and NE trending structures are the main ore controlling structures in the mining area, and the best prospecting location is the intersection of EW and NE faults in Carboniferous strata on both sides of folds; strata and lithology are the most possible sources of ore-forming materials. Based on the analysis of main ore controlling factors such as structure, strata and magmatic rocks, the metallogenic regularity and geological characteristics of Jinchangzi gold deposit are discussed.
