| 中文摘要:2007~2013年开展的内蒙古矿产资源潜力评价项目，对铁、铜、铅锌、金、银、钨、钼、铬、镍等重要矿种进行了区域成矿规律总结，为矿产资源潜力评价提供了基础资料。文章即是对该项工作部分成果的概括总结。主要进展包括：在全国Ⅲ级成矿区带划分的基础上，首次进行了覆盖全自治区的Ⅳ级成矿亚带的划分，共划分出34个Ⅳ级成矿亚带；对内蒙古铁、铜等11个重要矿种的主要矿床类型及成矿特征进行了概述，对其时空分布规律做了归纳，认为全区70%以上的矿床数量和资源储量均集中在Ⅲ-5、Ⅲ-6、Ⅲ-8、Ⅲ-10和Ⅲ-11五个成矿区带。此外，不同矿种甚至同一矿种，由于成矿地质背景的差异，在不同的三级区带中的分布也不一样。主要成矿期为元古宙和中生代，次为太古宙和晚古生代，不同矿种的重要成矿期也不完全相同。从区域演化的角度探讨了构造与成矿的关系，认为不同的构造演化阶段形成不同的矿床类型和不同矿种的矿床，其中，古大陆边缘裂谷带以白云鄂博式铁-稀土元素矿床为代表，而大兴安岭岩浆岩带则以产出与燕山期中酸性火山侵入杂岩有关的多金属矿产为特点。 |

| Abstract:Regional metallogenic regularity of important resources such as iron, copper, lead, zinc, gold, silver, tungsten, molybdenum, chromium and nickel were summarized by the Mineral Resources Potential Evaluation Project in Inner Mongolia which was carried out from 2007 to 2013, and the result provides the basic information for the mineral resources potential prediction. In this paper, some results of the work are summarized. The main ore deposit types and mineralization characteristics of 11 kinds of important mineral resources such as iron and copper in Inner Mongolia are summarized. On the basis of the national Ⅲ-grade ore-forming belts, Inner Mongolia was for the first time divided into 34 Ⅳ-grade ore-forming sub-belts covering the whole autonomous region. The temporal and spatial distribution of important minerals are summarized, and generally Ⅲ-5, Ⅲ-6, Ⅲ-8, Ⅲ-10 and Ⅲ-11 subbelts concentrate more than 70% of Inner Mongolia's mineral deposits and reserves. In addition, due to differences of geological background, the distribution of different types of minerals and even the same type of mineral is not the same. The main metallogenic epochs include Proterozoic and Mesozoic, followed by Archean and late Paleozoic, and the metallogenic epochs of different minerals are not exactly the same. The relationship between mineralization and tectonic evolution is discussed, and different types of ore deposits were formed due to different tectonic evolution stages. |
