Abstract: On the basis of 1∶50 000 stream sediment survey,GeoIPAS software is used to calculate the geochemical parameters in order to guide prospecting in Hongshan area in Chifeng,Inner Mongolia.The geochemical characteristics of stream sediment and the metallogenic geological characteristics in comprehensive study area are analyzed,and 7 comprehensive anomalies are delineated.The anomaly verification conducted on HS-5 comprehensive anomaly finds out gold mineralization clues in 1 quartz vein,indicating the stream sediment survey has good application results in prospecting in the study area,especially in gold prospecting applications.Based on comprehensive anomaly analysis and verification,as well as the mineral distribution characteristics,geochemical anomalous characteristics,geological characteristics in the study area and regional ore-forming geological conditions,3 metallogenic prospects are delineated,that is Langjunhala gold-copper metallogenic prospect,Sanjianfang copper-lead-zinc-silver metallogenic prospect and Hariwula gold-zinc-silver-copper prospect.
