摘要 前人在西藏当雄县拉屋多金属矿床开展过土壤吸附烃找矿有效性试验,试验表明已知矿体上方有良好的吸附烃异常
,取得了很好的试验效果。笔者在此基础上,进一步开展该方法的找矿应用研究。通过化探扫面,在拉屋矿区圈出了3个良
好的吸附烃异常,并相应地圈定了3个找矿预测靶区,经后来在1号预测靶区的有利地段进行了工程验证,结果发现了1条约
6 m厚的铜矿脉,初步工程验证结果证明吸附烃找矿预测效果良好。
Abstract : The effectiveness of the soil absorbed hydrocarbon method over ore bodies of the Lawu
polymetallic deposit in Dangxiong, Tibet was experimentally studied by previous workers, and the result
shows that the anomalies of adsorbed hydrocarbon are quite clear over ore bodies, and hence the method is
effective. On such a basis, the method was employed by the authors in exploration work. In the Lawu ore
district, three clear anomalies of hydrocarbon and three corresponding favorable oreprospecting targets
were delineated. A copper vein some 6m thick was later found in No. 1 target. All this proves the
adaptability and practicability of this method.
