地球化学方法在南祁连天峻县阳康曲一带找矿的应用

Application of geochemical method to prospecting in Yangkangqu area, Tianjun County, South Qilian

通过对南祁连天峻县阳康曲一带1∶20万水系沉积物ZHs-12号Au异常的查证,在该异常范围内圈出了AS22号1:5万Au异常,又对AS22号1:5万Au异常进行查证,采用1:1万土壤测量,又圈出了AP3、AP4两个土壤异常,在AP4号土壤异常中发现了多条金矿体,最终发现了青海省天峻县阳康曲陇王玛珠金、铁多金属矿,该矿床的发现表明了在该地区利用不同的地球化学方法进行找矿效果非常明显,对具有相类似的1:20万或1:5万水系沉积物异常进行查证,最终发现矿体,具有重要的指导意义。

Based on the verification of the 1:200 000 stream sediment ZHs-12 Au anomaly in Yangkangqu area,Tianjun County,South Qilian,the AS22 1:50 000 Au anomaly was circled within the anomaly range.And then the AS22 1:50 000 Au anomaly was verified.Using 1:10 000 soil survey,two soil anomalies,AP3 and AP4,were circled.A number of gold ore bodies were found in the AP4 soil anomaly.Finally,the Mazhu gold and iron polymetallic deposit in Yangkang Qulongwang,Tianjun County,Qinghai Province was discovered.The discovery of the deposit shows that the combination of different geochemical methods is very effective in prospecting in this area.It has great guiding significance to verify the anomalies of 1:200 000 or 1:50 000 stream sediments and eventually discover ore bodies.
