| 摘 要： | 应用土壤吸附烃测量法，在拉屋铜-铅-锌多金属矿区进行找矿研究．采集样品为土壤，层位为B层，岩性为风化残坡积土，样品总数为561个．样品分析采用酸解烃法，经处理分析数据，确定出矿区内吸附烃背景值为2．944μL／kg，异常下限为4．852μL／kg，并在矿区范围内圈出了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6m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 method of soil absorption of hydrocarbon is applied in this paper to explore Lawu Copper - Lead - Zinc polymetallic deposit in Tibet. The gathered 561 samples belong to soil of B layer of residual soil slope. The acidolysis hydrocarbon is then adopted to analyze these samples. Through processing analytical data, the hy- drocarbon background value is determined to be 2. 944 μL/kg and abnormality lower limit value is 4. 852 μL/ kg. Three abnormality of hydrocarbon are settled and three corresponding beneficial targets of prediction for exploring deposit are made clear. A copper vein about 6 m thick in No. 1 target is found in the project, which proves the feasibility of this method. |
