【摘要】 为了快速缩小找矿范围,提供有利靶区,基于1∶5万水系沉积物测量成果,对内蒙古敖汉地区的水系沉积物地球化学特征进行了分析,并结合研究区成矿地质条件共圈出22处综合异常,通过对HS-7综合异常进行查证,发现2条铜(银)矿化体,表明水系沉积物测量在该区具有较好的找矿效果,尤其对金、铜等矿种效果更加突出。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、化探异常特征、地质特征及区域成矿地质条件,共圈定4处找矿远景区,即:撰山子—关东沟金铜银找矿远景区、黄花甸—白土营子钼铜找矿远景区、水泉—大黄胡同铁铜萤石找矿远景区和下甸子铜钼找矿远景区,为进一步找矿工作指明了方向。更多还原

【Abstract】 The 1∶50 000 stream sediment survey was conducted in the Aohan area,Inner Mongolia.The paper ana-lyzed the geochemical characteristics of the stream sediment based the results,in order to quickly narrow the prospecting range and provide promising target areas.22 comprehensive anomalies were delineated in connection with the ore-forming geological conditions in the research area.The investigation of HS-7 comprehensive anomaly found 2 copper(silver) mineralization bodies.It shows that geochemical survey of stream sediments has good prospecting effect in this area,especially for gold,copper and other minerals.Based on the comprehensive anomaly analysis and investigation,in combination with the regional mineralization and local geological settings,4 potential prospecting areas were delineated including Zhuanshanzi-Guandonggou Au-Cu-Ag area,Huanghuadian-Baituyingzi Mo-Cu area,Shuiquan-Dahuanghutong Fe-Cu-fluorite area,Xiadianzi Cu-Mo area.The results provide reference for future prospecting.更多还原
