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。The discovery of a gold deposit of micrograined dissemination type in the southern part of Shanxi province was begun from a anomaly of stream sediments.After that using geological and geochemical countermeasude methods the repeatedly cheak up and survey were carried on,and a systimatic large-scale geochemical exploration was developed,then final a hopeful extra-large scale gold deposit has been found outBased on the study of geological and research results in the study area,the good prospecting result was got by the systimatic summarizing of geochemical characteristics,the probe into geochemical anomalymodel and prospecting criterias,and the comprehensive appraisal of the second anomaly inthe 1/10000 soil(rock)measurements.
