摘　　要：内蒙古自治区阿巴嘎旗必鲁甘干钼铜矿床,是内蒙古二连-东乌旗成矿带上近几年新发现的一个中型斑岩型矿床,矿体主要赋存于二长花岗斑岩及二叠系沉积地层中。化探工作发现,成矿元素Ag、Pb、Zn、Cu、Mo、W异常形态复杂,存在多个浓集中心,总体呈NE向展布,各元素异常浓度中心吻合,元素间套合良好。矿体形成与硅化、钾化、绢英岩化等蚀变有关,成矿与构造、岩浆活动、成矿热液活动关系密切。本文在总结该矿床的地质与化探特征基础上提出其成矿规律,为本区下一步找矿提供借鉴。The Bilugangan molybdenum deposit in Abaga, Inner Mongolia, is a medium porphyry deposit found in the Erlian-Dongwuqi metallogenic belt in the recent years. Ore bodies occur mainly in the monzo-granite-phohyry and Permian strata. The geochemical prospecting shows that the ore-forming elements of Ag, Pb, Zn, Cu, Mo and W abnormal shapes very complex, and have many concentration centers, which distributed in north-east direction. The element concentration centers coincide with each other well. Ore body formation is associated with silication, sericition and K-metasomatioin. Metallogenesis is related to the deep faults, magma activities and hydrothermal ore-forming solution. Summarizing the geological and geochemical prospecting characters for this deposit, we put forward its metallogenic regularity, which is an important clue to further prospecting work in the study area.
