摘要:
中国是全球铁矿石第一消费大国,每年进口铁矿石量已超过9亿t,进口量超过全球铁矿石贸易量的60%,对全球铁矿主要类型特征及重要分布区带总结和潜力分析研究具有重要的理论和现实意义。本文总结了全球铁矿资源的禀赋特征,将全球铁矿床分为BIF相关型、沉积型、火山成因型、岩浆型、接触交代-热液型(矽卡岩型)5种成因类型,重点总结分析了BIF相关型和火山成因型铁矿地质特征、成因和找矿标志等。根据铁矿床产出的大地构造单元、地层层序、含矿建造特征及矿床类型、成矿时代等综合因素,在全球主要大地构造单元中共圈出33个铁矿分布区,47个铁矿重要分布区带,并对各重要分布区带的资源潜力进行了探讨。

Abstract:
China is the world's largest consumer of iron ore. The annual import of iron ore has exceeded 900 million tons, and its imports exceed 60% of the global iron ore trade volume. The summarization and potential analysis of global iron ore type characteristics and important distribution zones are of important theoretical and practical significance. This paper sums up the endowment characteristics of global iron ore resources. The authors divide global iron deposits into five genetic types:BIF-related, sedimentary, volcanic, magmatic, and contact-hydrothermal (skarn) deposits, with the emphasis placed on the analysis of geological characteristics of BIF-related and volcanic iron ore deposits as well as genesis and prospecting indicators. According to the comprehensive factors such as tectonic units, stratigraphic sequence, ore-bearing structure characteristics, deposit types and metallogenic ages of iron ore deposits, a total of 33 iron ore distribution areas and 47 important distribution belts of iron ore deposits are delineated in the major geotectonic units of the world. In addition, the resource potential of each important distribution belt is discussed.
