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 Inner Mongolia Autonomous Region Apagiaqi Lulugan dry molybdenum-copper deposit is a medium-sized porphyry deposit newly discovered in recent years in the Erlian-Dongwuqi metallogenic belt of Inner Mongolia. The ore body mainly exists in two long granite Porphyry and Permian sedimentary formations. The geochemical exploration work found that the abnormal morphology of the ore-forming elements Ag, Pb, Zn, Cu, Mo and W is complex, there are many concentration centers, which are generally distributed in the NE direction, and the centers of anomalous concentrations of elements coincide with each other and the elements are well nested. The formation of ore bodies is related to the alteration of silicification, potashization and sericite alteration. The mineralization and tectonism, magmatic activity and ore-forming hydrothermal activity are closely related. This paper summarizes the geological and geochemical characteristics of the deposit on the basis of its metallogenic regularity, to provide reference for prospecting for the next step in this area.
