摘要
应用深穿透地球化学找矿方法,对常规化探方法难以奏效的草甸覆盖区进行土壤地球化学调查,探索草甸覆盖区隐伏及半隐伏金矿的找矿新方法。选定的手段是土壤剖面及面积性土壤测量,测定的相态是水提取金、有机结合金、自然金。通过本次工作,圈出了多片不同相态的异常。对个别异常进行验证,发现了金矿体,显示出该方法在本区使用的有效性,为甘南地区开展深穿透地球化学找矿工作提供了依据。
Geochemical prospecting method of deep penetration is a new tool to find hidden and half-hidden gold deposits in the meadow region which general geochemical prospecting method is not efficiency. Selected means are soil section and region surveys. Tracing phase states are water extracted gold, organic combined gold and nature gold. The method has been successfully used to find gold ores and provided geochemical prospecting targets in the southern Gansu province.
