| 摘 要： | 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.

| Abstract: | Heihe basin in the Qinghai province is located in the northern Qilian, which is a typical fault basin with excellent metallogenic factors. The basin is covered by different transported overburden since Cretaceous. In order to inquire into effects of geo-gas reconnaissance technique for concealed deposits in this kind of landscape, 4 points/Km2 griding method of geo-gas reconnaissance is adopt to circle distinct anomalous belts. Supported by matching area soil survey, it is indicated that the source of anomalous elements of geo-gas reconnaissance has no relations with overburden soil, and refleet deep-seated mineralization or structures. |
