摘　　要：以内蒙古中西部地区金属矿产地质分布特点为依据,在分析研究该区成矿地质背景、矿床(点)分布特征和构造演化等地质成果基础上,将本区划分为6个Ⅲ级成矿带、15个Ⅳ级成矿亚带,并对Ⅳ级成矿亚带地质特征进行了阐述,指出了各个成矿亚带的找矿方向。通过对本区内地质构造事件、地质成矿规律的分析,认为区内成矿类型齐全,且前寒武纪、海西期是本区最主要的两个成矿时期,在此基础上,提出了该地区的构造演化特征与成矿作用。On the basis of the geological distribution of metal mineral in Mid-Western area of Inner Mongolia, given the analysis of previous geological work of geological setting of ore-forming processes and deposits（points） distribution characteristics and tectonic evolutionary characteristics, the ores in this area are grouped into six grade Ⅲ rnetallogenic belts and fifteen grade Ⅳ metallogenic sub-belts. The geological features of the fifteen metallogenic sub-belts are particularly described, and the article points out the prospecting direction of these metallogenic sub-belts. Based on the analysis of geological tectonic events and geological mineralization law, it is thought that metallogenic types are diverse and rich. Precambrian and Hercynian are two of the most main metallogenic periods in this area. In addition, the author further proposes the characteristic of tectonic evolution and mineralization.
