中国镍矿资源现状与国家级镍矿床实物地质资料筛选

中国镍矿资源具有分布高度集中、开采条件差、矿床类型以岩浆型为主、伴生矿种多、对外依存度高等特点.基于中国镍矿资源现状,并结合实物地质资料的筛选原则,归纳了国家级镍矿实物资料的筛选条件:成因典型、产于重点成镍带或主要成矿时代和矿床规模大,并提出了33个符合国家实物地质资料馆收藏的镍矿目录,反映了中国镍矿的成矿特征,为建立...

Current status of nickel ore resources in China and state-level screening of geological physical samples for nickel ore deposits KONG Linghu1, DENG Wenbing1,2, SHANG Lei1

China's nickel ore resources are characterized by the highly concentrated distribution,poor mining conditions,whereas high dependence on foreign imports.The deposit are mainly composed of magmatic type and associated with abundant other minerals.Based on the current status of China’s nickel ore resources and combined with the screening principles of geological physical samples,this paper summarized the screening criteria of state-level nickel ore.The criteria were followed as:the typical genesis,orientation in key nickel metallogenic belts or in the main metallogenic epoch in a large scale.The 33 catalogues of nickel ore deposits which follow state-level standard of National Geological Physical Sample Archive were proposed.The research can provide reference on the construction of nickel ore archiving system and the scientific collection approaches to physical geological samples.
