中国铁矿资源现状与铁矿实物地质资料筛选

依据我国铁矿资源的类型、成矿区（带）和赋存特点，概述了当前我国铁资源的状况，提出了铁矿资源进行实物地质资料筛选要考虑的因素。结果表明：中国铁矿床类型齐全，以沉积-变质型为主，岩浆型、接触交代-热液型次之；我国铁矿床成矿条件复杂，大型、超大型矿床少，贫矿多、富矿少，且伴（共）生有益组分多，但呈现相对集中分布的特点，主要包括鞍山-本溪、攀西-滇中、冀东-密云、长江中下游、鄂西-湘西北、邯郸-邢台等6个成矿区（带），新疆地区铁矿资源潜力巨大，是未来找矿的重点；铁矿资源实物地质资料筛选应考虑铁矿床成矿规模、成因类型、成矿时代、成矿区（带）等因素，兼顾具有典型、潜力巨大的铁矿床作为筛选对象。

Current Status of Iron-Ore Resources in China and Screening of Object Iron-Ore Geological Data

In this study, we summarized the current status of iron-ore resources in China, and proposed the factors which influence screening object iron geological data based on the iron ore deposit types, mineralization areas (belts) and occurrence characteristics. The results indicate that deposit types of iron deposits in China are dominated by the sedimentary-metamorphic type, followed by the magmatic type and contact alteration-hydrothermal type. The metallogenic conditions of the iron ore are complicated in China, which plays host to a few large-size and super-large-sized iron deposits, many poor iron-ore and few rich iron ore areas, with lots of associated useful compositions. These iron-ore deposits display a relatively centralized distribution, mainly distributed in the Anshan-Benxi, Panzhihua-Xichang-middle Yunnan Province, east Hebei Province-Miyun county, middle and lower reach of the Yangtze River, mining west Hubei Province-northwest Hunan Province and Handan- Xingtai areas. The iron-ore resources in Xinjiang has a great potential which is an important ore prospecting area in the future. Screening of object iron-ore geological data should consider scales of iron-ore deposits, genetic types, metallogenic epochs, and mineralization areas (belts), as well as the typical iron deposits with enormous potential.
