Abstract: Molybdenum is a rare metal mineral resources of strategic importance in the world.In order to analyze the molybdenum resources distribution characteristics and molybdenum deposit research status,the international status,ore deposit distribution characteristics,ore deposit types,ore-forming tempreature and metallogenic epoch of the molybdenum resources in China are analyzed in depth,the results show that:①the molybdenum resources and production are both ranking first in the world,but far from being a powerhouse of molybdenum resources;②the porphyry type,skarn type and vein type are the main genetic types of molybdenum deposit,the porphyry type and skarn type molybdenum deposits are belongs to middle-high temperature deposits,the vein type molybdenum deposit are analyzed to middle-low temperature deposit;③the metallogenic age of molybdenum deposit is relatively late,it focus on Yanshannian-Himalayan.Based on the above analysis results,the existed research results of ore-forming materal source and ore-forming fluid souces of molybdenum deposit are researched in depth,the following conclusions are concluded:①the ore-forming material source of molybdenum deposit in our country is complex,they are shell source,mantle source and crust-mantle mixed source;②the magmatic hydrothermal is the main source of ore-forming fluid,the atmospheric precipitation occupies a very important position;③the current research results of the ore-forming material source of molybdenum deposit in our country is inaccurate,the molybdenum isotopic characteristics will be an effective means of tracing ore-forming material source;④there are many problems are existed in the process of analyzing ore-forming fluid source by using hydrogen and oxygen isotope,so,it is necessary to adopt a varity of integrated tracing methods to analyze the ore-forming materal source of molybdenum deposit comprehensively to realize the goal of mutal complement and authentication,therefore,it is the best method to analyze the ore-forming fluids of molybdenum deposit.
