Abstract: Dayingzi Region is in the central part of Eastern Liaoning-Southern Jilin Metallogenic Belt.Its metallogenic geological conditions are favorable.On the basis of 1:50 000 stream sediment survey,the geochemical characteristics and mineralization prospects in the region are preliminarily evaluated.According to the distribution characteristics of ore-forming elements,R-type cluster analysis and factor analysis,11 composite anomalies are delineated.The preferred composite anomalies were then scored and accordingly ranked,leading to the determination of 3 prospective areas metallogenesis.According to mineralization clues on the ground surface,the composite geological conditions for mineralization,the scoring and ranking of geochemical composite anomalies and the resources verification work,the HS05 composite anomaly was selected as the prospecting target.At the same time,the ore-prospecting significance of the research in Dayingzi Region is put forward,in hope that it can be used as reference for future prospecting.
