    APPLICATION OF PHASE-STATE STUDY IN GEOCHEMICAL ANOMALY EVALUATION: A case study of evaluation for Majiazi stream sediment anomaly

      摘要
    • 摘要: 利用相态研究可确定异常元素的赋存状态,马架子水系沉积物综合异常强度高,浓集中心明显,经过几次异常检查及查证,未获得良好的找矿效果,引起异常的成因机制不清。对异常样品中元素在氧化物相、结合相及硫化物相中分配的综合研究证实,Ph、Zn元素主要是以均匀分散形式存在于岩石中,为非矿致异常,从而节省了大量的人力、财力及物力,为异常查证及评价提供了一套新的思路。

       

      Abstract: The anomaly of stream sediments in Majiazi area is with high strength and sensible concentrated center, but the genetic mechanism of the anomaly has not clearly recognized after a few times of anomaly inspection and investigation. The study on distribution of abnormal elements in oxide-facies, combination-facies and sulfide-facies shows that the Pb and Zn elements are evenly distributed in the rocks. The anomaly is not caused by mineralization.
