| 摘 要： | 挥发性有机化合物及硫化物气体作指标勘查金属矿床的工作国内外均处于初试阶段。近几年我们用硫化氢、二氧化硫及轻烃气体(C1—C4烷烃和烯烃)作指标对十个不同景观条件不同地区的铅锌矿、铜钼矿、金矿、铜镍等多金属矿床进行了土壤及地表岩石测量勘查隐伏矿的方法试验,取得很好的结果。表明该方法是寻找多金属隐伏矿的一种有效的气体测量方法,它可用于寻找覆盖厚度几米到400多米运积物覆盖区隐伏矿及基岩面下埋藏400多米盲矿的地表土壤和岩石测量以及岩体评价找矿工作。试验结果还表明该方法用于岩石测量的效果优于土壤测量。

| Abstract: | The utilization of volatile organic compounds and sulfide gases as indices in the exploration of metallic deposits is merely at the preliminary test stage both in China and abroad. In recent years, the authors used hydrogen sulfide dioxide and light hydrocarbon gases (C1—C4 paraffin and olefin) as indices to perform the test on the exploration of concealed deposits through soil and surface rock survey within ten lead-zinc, copper-molybdenum, gold and copper-nickel polymetallic deposits in different areas and under different landscape conditions and, as a result, obtained excellent results. It is demonstrated that the method is an effective gasometric technique used in surface soil and rock survey as well as rock body evaluation with the purpose of looking for concealed deposits beneath transported overburden several to more than 400m in thickness and blind deposits over 400m under the bedrock surface. Tests also show that this method is more effective in rock survey than in soil survey. |
