摘　　要：通过对区域地质概况,土壤、岩石地球化学元素异常特征的研究,在九仗沟异常内发现M1矿脉,在阴坡异常带内发现了隐伏矿体,在张家沟异常带也发现了矿点,事实证明土壤、岩石地球化学元素异常特征对矿体具有很好的指示作用。受成矿热液作用程度的不同,成矿元素组合也不同,通过对大量样品中的元素进行相关关系和R型聚类分析,得出成矿过程中成矿元素与伴生元素的自然组合特征。通过对异常元素的空间分布、对比值特征的研究和分析,可以得到成矿作用的地球化学过程中含矿热液携带成矿元素沿构造破碎带运移方向和富集位置特征,进而可以定位矿床的具体位置和矿化信息的预测,尤其对寻找隐伏和深部矿床更有效。Through the research of the geology of the region and the analysis of the characteristic of soil, rock geochemistry elements, the M1 mineral vein in Jiuzhanggou are prospected, concealed ore deposit in Yinpo and mine in Zhangjiagou. It is proven by the practice that the characteristic of geochemistry abnormality of soil and rock has an effective indication function to the mineral body. For the difference of effect of the hot liquid, the combination of the mineral chemical elements is also different. Through the research and analysis of the correlation coefficient and the R model of cluster of elements, the natural combination characteristic of the mineral chemical elements and the living elements in the mineralizing process is described, and the transfer direction and gathering position characteristic of the elements of hot liquid are presented by the research and analysis of the characteristic of space distributing（including horizontal zoning and vertical zoning）and contrast value features of abnormal chemical elements of the deposit, and then the precision position and mineral information can be ascertained, it is particularly effective in prospecting the concealed ore deposit and deep deposit.
