Abstract

Zhongzhai-Shilipu area is located in the west of the Zhaishang super-large gold mine area,and its metallogenic conditions are favorable.The 1∶50 000 stream sediment survey is carried out in this area.The geochemical characteristics of 17 elements in this area are studied,which showed that the stratigraphic units of Zhongzhai-Shilipu area are the favorable geochemical blocks.Using the method of mathematical statistics,the relative abundance,relative coefficient of variation and enrichment degree of ore-forming elements were analyzed,and the favorable parts of polymetallic mineralization were pointed out.The metallogenic potential of each stratigraphic unit was evaluated by calculating prospecting potential index(k× Cv) of ore-forming elements in different strata.The correlative character and spatial distribution of elements are studied,the spatial distribution characteristics and combination relations are discussed by R cluster analysis of 17 elements from 3 904 samples in the working area.According to the abnormal geochemical characteristics,strata and fault structure,four mineralization prospects are selected.On the basis of carrying out abnormal verification and deploying the project,three  Au-Sb ore occurrences were found,and achieved good prospecting effect.
