中文摘要:镍矿曾经是中国的传统优势矿产,但目前已大量进口,成为典型的关键矿产(critical minerals)。本文基于镍矿地质大数据,系统分析了世界及中国镍矿的资源概况,总结了中国镍矿的时空分布规律,采用量化方法研究了中国省、市、县级、Ⅲ级成矿区带及各成矿时代的镍矿成矿密度与成矿强度。研究表明,中国镍矿资源丰富,分布相对集中,具有较大的资源潜力和找矿前景。类型以岩浆型为主,主成矿期为晚古生代;将中国镍矿划分为30个成镍带并分为重要和一般成镍带两个等级,其中重要成镍带有12个;厘定18个镍矿成矿系列,23个亚系列;指出今后深部找矿、西部找矿、有找矿潜力的现有矿山及成矿强度较高矿山的深部、边部及外围是镍矿找矿的重点工作区域,并对未来镍资源调查和产业发展提出了建议。

A quantitative study of metallogenic regularity of nickel deposits in China and their prospecting outlook
Abstract:Nickel minerals were traditional dominant minerals in China but with the present reliance on imports have become typical critical minerals. Based on the geological big data on nickel deposits, this study systematically analyzed the availability of nickel deposits in China and the world, summarized their temporal- spatial distribution, quantitatively analyzed the metallogenic density, and intensity of nickel deposits at various county, city, provincial levels, Ⅲmetallogenic belt and the metallogenic epoch. The results show that the nickel resources in China are abundant and concentrated, and have high exploitation potential. The main type is magmatic type and the metallogenic period was late Paleozoic. The nickel deposits in China are divided into 30 nickel- forming belts including 12 important, and 18 general belts, 18 identified nickel deposits, and metallogenic series with 23 sub- series. Deep prospecting, western prospecting, existing mines with prospecting potential, deep, edge and periphery of mines with high metallogenic intensity are the key areas for nickel deposit prospecting in the future. Ideas for future nickel resources investigation and industrial development are proposed.
