摘　　要：根据中国钼矿床的成矿类型、成矿规模、成矿时代和分布等特点,简述了我国钼矿资源现阶段状况,提出了我国钼矿床实物地质资料筛选需要考虑的条件。结果表明:我国钼矿床类型多,以斑岩型为主,矽卡岩型次之,热液脉型、沉积型、海相火山岩型较少;我国钼矿床规模大,现阶段勘探、开发的矿床以大型、超大型矿床为主;钼矿床的成矿时代以燕山期成矿为主,其次为喜山期、印支期和海西期;钼矿床资源分布广泛,相对集中在燕辽、东秦岭、小兴安岭-张广才岭和大兴安岭4个钼矿矿集区。根据我国钼矿资源特点,结合国家实物地质资料馆馆藏规划,提出了当前符合国家实物地质资料馆收藏保管的34个钼矿床名录。Based on the metallogenic type, metallogenic scale, metallogenic ages and distribution of molybdenum ore deposits, we summarized the current status of molybdenum ore resources in China, and proposed the considered factors when screening geological material data of molybdenum deposit. The results indicated that molybdenum ore deposit types in China were dominated by porphyry type,secondly for skarn type,hydrothermal vein type, sedimentary rock type and marine volcanic type were less. Molybdenum ore deposits were mostly large scale in China, large-size and super-large molybdenum deposits were mainly in the exploration and exploitation of molybdenum minerals at present. Metallogenic ages of molybdenum ore deposits in China were dominated by Yanshanian, followed by Himalayan period, Indo-Chinese epoch and Hercynian. Molybdenum ore resources were widely distributed but relatively centralized distributed into 4 ore concentration areas, which were Yanliao, East Qinling, Xiaoxing - an Range-Zhangguangcai Range and Greater Khingan Mountains respectively. According to the characteristics of molybdenum ore resources in China, combined with schemes of National Physical Geological Data Archives, proposed 34 names of molybdenum ore deposits which fit for the current collection system construction of National Physical Geological Data Archives.
