摘　　要：吉家洼金矿床位于豫西熊耳山金银多金属矿集区内,近年来其深部找矿取得了一定进展。为开展进一步找矿勘查工作,在吉家洼金矿区应用激电测深取得了较好的探测效果。视极化率对含矿地质体的反应较为敏感,激电测深在16勘探线以北探测到高极化地质体,推测深部存在自北东向南西方向延伸的隐伏含矿斑岩体。通过钻孔原生晕样品测试,发现16勘探线具有高温元素W异常,侧面验证了激电测深的预测结果。该研究结果对熊耳山金银多金属矿集区勘查脉状金银多金属矿化具有一定借鉴意义。Jijiawa Gold Deposit is located in Xiongershan gold-silver polymetallic ore concentration area in western Henan Province.Some progress has been made in deep prospecting in recent years.In order to carry out further prospecting,the IP sounding method has achieved good results in Jijiawa Gold District.The apparent polarizability parameters are sensitive to the ore-bearing geological bodies,and the highly polarized geological bodies are detected in the north of the No.16 exploration line.It is inferred that there is a concealed ore-bearing porphyry body extending from northeast to southwest in the depth of the deposit.Through borehole primary halo sample testing,high-temperature element W anomalies are found on the No.16 exploration line,indirectly verifying the prediction results of IP sounding.This study result has certain reference significance for prospecting the vein gold-silver polymetallic deposits in Xiongershan gold-silver polymetallic ore concentration area.
