摘　　要：水泉沟一带位于马兰峪复背斜西段,是金、铁、钼等矿产的集中产地,具有良好的成矿地质条件。通过在水泉沟一带开展1∶1万土壤地球化学测量工作,运用元素的变异系数、富集系数及相关性分析、因子分析等技术方法,对12种元素的测试结果进行了统计分析,结果显示:Au、Ag元素具有富集成矿的潜力;圈定出以Au、Ag为主成矿元素的综合异常4处,并对其中2处开展了工程揭露,证实为矿致异常。运用相似类比法对金资源量进行预测,进一步证明水泉沟一带具有良好的找矿潜力。Shuiquangou Area is located in the western section of the Malanyu anticlinorium.It is a concentrated production area of gold,iron,molybdenum and other minerals,and has good metallogenic geological conditions.By carrying out 1∶10000 soil geochemical survey in the area,using elemental variation coefficient,enrichment coefficient,correlation analysis,factor analysis and other technical methods,the test results of 12 elements in the soil in this area are statistically analyzed,showing that Au and Ag have the potential to enrich and mineralize;4 comprehensive anomalies with Ag and Au as the main ore-forming elements have been delineated,and 2 of them have been revealed by engineering works,which proved to be ore-induced anomalies.The similar analogy method is used to predict the amount of gold resources,which further proves that Shuiquangou Area has good metallogenic potential.
