摘　　要：中国锰矿资源具有资源量丰富、矿床规模小、分布不均、品位普遍较低、成因类型复杂、成矿时代跨度大、对外依存度高等特点。截至2016年底,国内锰矿(矿石)查明储量为15.51亿t,矿床数量庞大,产生了大量实物地质资料。基于中国锰矿资源现状,结合实物地质资料的筛选原则,本文总结了国家级锰矿的筛选条件,即矿床规模大、品位高、成因典型,分布在重点成矿区或主要成矿时代和其他入选条件,并在全国范围内初步筛选出35个符合国家实物地质资料馆收藏的锰矿目录,反映了中国锰矿的成矿特点,为系统开展锰矿实物地质资料采集提供了科学依据和服务支撑。China's manganese ore resources are characterized by abundant resources,small scales,uneven distribution,generally low grades,complex genetic types,large span of metallogenic epoch,and high dependence on foreign countries.By 2016,the proven reserves of domestic manganese ore are 1.551 billion tons,and the number of deposits is huge,resulting in a large amount of physical geological data.Based on the current status of China s manganese ore resources,and combined with the selecting principles of physical geological data,this paper summarizes the selecting criteria of national manganese ore,that is,the scale of the deposit is large,the grade is rich,the genesis is typical,the distribution is in the key metallogenic area or the main metallogenic epoch and other criteria.A total of 35 manganese ore catalogues in line with the collection of the National Physical Geological Data Archives selected nationwide,reflects the metallogenic characteristics of China s manganese ore,provides scientific basis and service support for the systematic collection of manganese ore geological data.
