青海省黑河盆地是北祁连地区一个典型的断陷盆地,具有良好的成矿条件,然而却被白垩纪以来各种运积物覆盖,为探讨该景观条件下寻找隐伏矿地气普查方法的效果,文章采用4个/km2的网格化地气普查方法,圈出明显的异常带,并通过配套的土壤面积测量研究表明,地气测量金属异常元素来源与覆盖层土壤无关,可能反映了深部的矿化或构造。 Heihe Basin, Qinghai Province, is a typical faulted basin in the northern Qilian area with good metallogenic conditions. However, it has been covered by various transport materials since the Cretaceous. In order to explore a method for the general survey of concealed mineral gas in this landscape, The results show that the source of anomalous metals in geo-gas is irrelevant to the soil of the overburden, which may reflect the fact that Deep mineralization or structure.
