摘要
Abstract
The Dashimodong area is located in the Erguna Block,which belongs to the eastern segment of Xing'an-Mongolia Orogenic Belt.Regionally,the area is potential for the porphyry and epithermal deposit prospecting.Geochemical soil survey at 200 m × 20 m grid was conducted in the study area to analyze metallogenic and geological and geochemical conditions.The results were analyzed with cluster analysis and factor analysis method showing high possibility of metallogenic process of Au,Ag,Cu,Pb,Zn.According to calculation of the background value and anomaly threshold of each element 70 single element anomalies are delineated.Combined with geological conditions and the anomaly characteristics we extracted 5 prospecting targets of which 1 is target Ⅰ and 3 are target Ⅱ.关键词
