中国铁矿床伴生关键金属:基本特征、分布规律及资源潜力
Iron deposits associated critical metals in China:Basic features,distribution,and resource potential
摘要
Abstract
The crucial role of critical metals in the high-tech development of a nation cannot be overstated.In recent years,due to the advancement of technological revolution and the growth of emerging industries,the competition for critical metal resources among countries has intensified.Critical metals in China correspond roughly to the"Four-type Rare Metals"and are primarily associated with various types of ore deposits.Iron deposits,one of the most widely distributed and well-studied metal deposit in China,has received considerable attention in terms of ore deposit types and genesis.However,research on the associated critical metals has been insufficient.Based on extensive literature research,this article systematically summarizes the basic features and distribution patterns of critical metals in Chinese iron deposits,and provides a preliminary assessment of the resource potential of these critical metals.The study reveals that the associated critical metals in iron deposits are primarily those rare metals such as rare earth elements,Sc,Nb,Ta,PGE,Co,Ni,Ga,Ge,Se,Cd,In,Te and Re,as well as non-ferrous metals like Mn,Ti and V.The distribution area of associated critical metals in Chinese iron deposits could be classified into five metallogenic provinces:western margin of Yangtze Craton,middle-lower Yangtze River,western Shan-dong,northern margin of North China Craton and Bainaimiao-Dongshengmiao region.Intensive studies on the occurrence and super enrichment mechanisms of associated critical metals in iron deposits will provide valuable references for the comprehensive utilization of critical metal resources and mineral exploration.In addition,the related research will enhance China's critical metal resource reserves and international competition.关键词
