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 thesame. 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.
