摘　　要：内蒙古扎鲁特旗架子少冷矿区1∶2万土壤测量异常,元素组合复杂,虽然面积不大,但强度高,各单元素异常均具有较好的浓集中心。尤其Zn、Pb、Cu等元素呈现高度富集。该土壤异常分布在满克头鄂博组火山岩地层中。经对该异常踏勘,发现较强的褐铁矿化及硅化、孔雀石化、蓝铜矿化等。经土壤剖面测量也发现较好Zn、Pb、Cu土壤异常,具重现性,与1:2万土壤异常浓集中心相吻合。经工程揭露,在满克头鄂博组火山岩和次火山地层中上发现了锌、铜矿化。经测试,部分样品快达到最低边界品位,矿化蚀变带较宽,有较大的找矿意义。该处成矿条件好,是锌、铜等多金属矿产成矿有利地段。为寻找以锌为主多金属矿产提供了明确靶区。Jiazishaolen ZhaluteCounty Inner Mongolia mine 1：2 soil anomaly, less is more than one element combination corn- plex abnormalities, area is not large, but the intensity is high, tile single element anomalies are good strong heart. Especially the elements such as zinc, Pb, Cu present highly enriched. The abnormal distribution of soil in full, head of the bayan oho group volcanic rock formation. After the abnormal reconnaissance, found that the stronger limonite and silicide, peacock petrochemical, azurite etc. Better the soil profile survey also found that zinc, Pb, Cu soil anomaly, reproducibility, soil anomaly with 1：2 is strong mental focus. The engineering, in full, head of the bayan obo group volcanic rocks and volcanic, formation and upper discovered the zinc and copper mineralization. After the test, some samples nearly reached the lowest cutoff grade, mineralized alteration zone is wide, have larger prospecting significance. Is there good metallogenic conditions, zinc, copper and other metals mineralization favorable location. Looking for is given priority to with zinc polymetallic minerals provides a clear target.
