摘　　要：陕南某微细浸染型金矿床是从发现金矿田（床）水系沉积物异常开始，运用地质、地球化学综合方法对异常反复踏勘检查，系统开展大比例尺化探详查找矿程序后找到一处有望成特大型的金矿床。在研究本地区地质、科研成果基础上，系统总结地球化学特征，探讨了化学异常模式和找矿标志，对１／１万土壤（岩石）测量的乙类异常进行了综合评序，取得良好的找矿效果。With the discovery of stream sediment anomalies found in a gold field (deposit),a giant gold deposit,which was expected to be a microfine-grained disseminated one,is uncovered after repeated reconnaissance surveys and examinations of theanomalies using integrated geological and gelchemical methods coupled with systematic geochemical follow-ups on largescales. Based on the achievements scored in geologic and scientific reseach into this area,geochemical characteristics are systematically summed up and approaches are made to geochemical anomaly pattern and ore-hunting evidence,with satisfactoryresults obtained by integrated evaluation of the deduced anomalies caused by buried ore body through pedogeochemical (litho geochemical) surveys on a scale of 1: 10,000.
