摘　　要：在对甘新蒙北山地区成矿地质背景和成矿在时空上的联系性等综合研究分析基础上,运用新理论、新认识,以板块构造单元划分为基础,将本区划分为3个Ⅲ级成矿带、11个Ⅳ级成矿带,并对Ⅲ级成矿带特征进行了阐述,以期为矿产勘查和地质大调查工作部署提供新的思路和依据。进一步就主要矿床(点)、构造单元、矿种、赋矿建造、控矿因素、成矿类型、成矿时代等方面进行了对比,认为各Ⅳ级成矿带在区域上具有相对稳定的展布范围,具有相同的构造环境和成矿条件、类似的矿种和成矿时代,存在一定的相似性、可比性,并且各成矿带具有一定的潜在找矿价值。According to the geological background and temporal and spacial relationship of the ore deposits in the Beishan area of Gansu-Xinjiang-Iner Mongolia, which is an important mineral resources concentration area in west China, and based upon the comprehensive study on exploration and geological survey as well as new theory of geology, the ores in this area are grouped into three grade Ⅲ metallogenic belts and eleven grade Ⅳ metallogenic sub-belts. The three metallogenic belts of grade Ⅲ are particularly described for the purpose of supplying clue and basis to mineral exploration and geological survey. There exist numerous mineral occurrences and mineral clues as well as plenty of geological, geophysical and geochemical anomalies which are expecting to be investigated and verified in the area.
