内蒙古赤峰红山地区水系沉积物异常评价及找矿方向

为进一步指导内蒙古赤峰红山地区找矿,在1∶5万水系沉积物测量成果的基础上,利用GeoIPAS软件对研究区地球化学参数进行计算,分析了水系沉积物地球化学特征,综合研究区成矿地质特征,共圈出7处综合异常。对HS-5综合异常进行了异常查证,发现1条石英脉具有金矿化显示,表明水系沉积物测量在研究区的找矿中具有较好的应用效果,尤其是在金的找矿应用上。在综合异常分析和查证的基础上,结合区内的矿产分布特征、地球化学异常特征、地质特征及区域成矿地质条件,共圈出成矿远景区3处,即郎郡哈拉金铜成矿远景区、三间房铜铅锌银成矿远景区和哈日乌拉金锌银铜成矿远景区。

Stream sediment anomaly evaluation and prospecting direction in Hongshan area in Chifeng,Inner Mongolia

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 characteristics 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.
