【摘要】：为深入剖析我国钼资源分布特征与钼矿床研究现状,对我国钼资源的国际地位、矿床分布特征、矿床类型、成矿温度、成矿时代进行了系统分析,结果表明:1我国钼资源量和产量均居全球首位,但并未成为钼业强国;2钼矿床主要成因类型为斑岩型、矽卡岩型和脉型,斑岩型和矽卡岩型钼矿属中—高温成矿,脉型钼矿属中—低温成矿;3钼矿床成矿年龄相对较晚,主要集中于燕山期—喜马拉雅期。在上述分析的基础上,综合分析了有关钼矿资源成矿物质来源、成矿流体来源等方面的研究成果,得出以下结论:1我国钼矿的成矿物质来源复杂,既有壳源、幔源,也有壳幔混源;2成矿流体来源以岩浆热液为主,大气降水在其中占有十分重要的地位;3钼同位素特征是未来示踪成矿物质来源的有效手段;4鉴于利用流体包裹体氢氧同位素研究成矿流体来源存在许多问题,认为有必要运用多种示踪方法进行综合研究,相互补充和验证,是准确推断成矿流体来源的最佳途径。
[Abstract]:In order to deeply analyze the distribution characteristics of molybdenum resources and the present research situation of molybdenum deposits in China, this paper makes a systematic analysis of the international status of molybdenum resources in China, the distribution characteristics of deposits, the types of deposits, the metallogenic temperature and the metallogenic epoch. The results show that: (1) the molybdenum resources and output of our country are the first in the world, but they are not powerful countries in molybdenum industry; (2) the main genetic types of molybdenum deposit are porphyry type, skarn type and vein type, porphyry type and skarn type molybdenum ore belong to medium-high temperature mineralization, vein type molybdenum ore belongs to medium-low temperature mineralization; 3 the metallogenic age of molybdenum deposit is relatively late, mainly concentrated in Yanshanian and Himalayan epoch. On the basis of the above analysis, this paper synthetically analyzes the research results on the source of molybdenum ore resources and ore-forming fluids, and draws the following conclusions: 1 the source of molybdenum ore in China is complex, with both crust and mantle sources. There are also crust-mantle mixed sources; (2) the source of ore-forming fluid is mainly magmatic hydrothermal fluid, in which atmospheric precipitation occupies a very important position, and molybdenum isotope feature is an effective means to trace the source of ore-forming material in the future; 4 in view of the many problems existing in the study of the source of ore-forming fluids by using the hydrogen and oxygen isotopes of fluid inclusions, it is considered that it is necessary to use various tracer methods to conduct comprehensive research, complement and verify each other, which is the best way to accurately infer the source of ore-forming fluids.
