    地物化方法在航磁异常查证中的应用

    INTEGRATED APPLICATION OF GEOLOGICAL, GEOPHYSICAL AND GEOCHEMICAL METHODS IN AEROMAGNETIC ANOMALY VERIFICATION

    • 摘要: 航磁异常查证是矿产勘查中的一个重要环节,其目的是通过地面查证,确定异常是否存在,追踪异常源,了解异常源所处的地质环境,对异常作出客观评价,提出进一步工作的建议,为后续资料解释提供依据.通过使用地物化综合方法对黑C-2011-02243号异常查证发现:地质剖面测量和土壤地球化学测量可在地表发现较好的找矿线索;高精度磁测及激电中梯测量则反映了深部地质体及矿化特征.依据查证结果认为,在进行航磁异常查证工作时,可优先进行剖面性的地质、高精度磁法及土壤地球化学测量工作;在分析上述测量结果的基础上安排剖面性的电法测量;如存在进一步找矿信息,可安排面积性物化探测量及工程验证工作.

       

      Abstract: As an important part of mineral exploration, aeromagnetic anomaly verification aims to determine the existence of anomaly, trace anomaly source, investigate its geological environment, make objective evaluations, put forward suggestions for further work, and provide basis for later data interpretation through ground check. The integrated application of geological, physical and chemical methods on the anomaly verification of H-C2011-02243 shows that the geological profile and soil geochemical surveys can find good prospecting clues on the surface, while the high-precision magnetic and induced polarization (IP) intermediate gradient surveys reveal the characteristics of deep geologic bodies and mineralization. It is thought that the geological, high-precision magnetic and soil geochemical surveys of profiles should be carried out first, then the IP surveys based on the above results, finally the geophysical-geochemical surveys and prospecting engineering once the favorable prospecting information is obtained.
