陕南某微细浸染型金矿床是从发现金矿田（床）水系沉积物异常始，经运用地质、地球化学综合方法对异常反复踏勘检查的关键环节到系统开展大比例尺化探详查的找矿程序，找到的一处有望成特大型的金矿床。在研究本区地质、科研成果基础上，系统总结地球化学特征，探讨了地球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。 A finely disseminated gold deposit in southern Shaanxi was discovered from sediment anomalies in the gold mine bed (bed) water system. By using the comprehensive geological and geochemical methods, the key links of abnormal and repeated reconnaissance inspections to the system were investigated by large-scale geochemical exploration Mine procedures, one is expected to find large gold deposits. Based on the study of geology and scientific research achievements in this area, the geochemical characteristics are systematically summarized, the geochemical anomaly patterns and ore-prospecting indicators are discussed, and the class B anomalies measured in 1/100000 soil (rock) Prospecting effect.
