| [摘 要]喇嘛朝鲁图铜钼矿床是近几年在蒙古国东部发现的一处中型斑岩型矿床。该矿床的形成与华力西晚期、燕山期的构造、岩浆活动关系密切，具有较明显的叠加成矿特征。通过对矿床成因、地球化学特征、蚀变带分带特征及矿化特征等进行综合对比分析，将该斑岩型矿床与南部的查布浅成中低温热液脉型铅锌银矿床归纳为一个统一的矿床成矿系列，初步建立了斑岩型-浅成中低温热液脉型成矿模式，在此基础上对矿区及其外围进行了成矿预测。 |

| Abstract: The Lamachaolutu copper-molybdenum deposit is a medium-sized porphyry deposit discovered recently in eastern Mongolia. Its ore-forming process was closely related to the tectonic and magmatic acivities in the late Variscan and Yanshanian periods, with obvious superimposed mineralization features. Through comprehensive studies on its ore genesis, geochemistry, alteration zonation and mineralization, we infer that this deposit and the Chabu epithermal low-temperature hydrothermal vein-type lead-zinc-silver deposit are in a unified metallogenic series, and we establish a porphyry-epithermal low-temperature hydrothermal vein-type metallogenic model. On this basis, we forecast the prospecting targets in the mining area and its periphery. |
