内蒙古西乌旗大地构造位置属华北板块北大陆边缘古生代陆缘增生带，中生代则处于滨太平洋构造域之大兴安岭中生代火山-岩浆岩带的南部边缘。由于受古亚洲构造成矿域与环太平洋构造域的叠加、复合和转换，该区成矿地质条件优越，成矿期次多、强度大，矿床类型多样，区域成矿特征十分复杂。在详细的野外工作基础上，通过对西乌旗区域构造、岩浆岩、地球物理、地球化学等区域地质成矿背景及区域构造演化的研究，对成矿作用类型及其与区域构造演化的关系进行了阐述，认为断裂构造和岩浆活动为两个重要的成矿地质条件和决定性的成矿控矿因素，控制和决定了研究区矿床、矿体的形成与空间分布。

The West Ujimqin banner of Inner Mongolia is tectoni-cally situated at Paleozoic continental margin accretionary belt in north continental margin of North China plate, while in the Mesozoic it is situated at the South margin of Greater Khingan Range Mesozoic vol-cano-magmatite belt in peri-Pacific tectonic domain. Because of the superposition and transformation of the paleo Asian tectonic metallo-genic province and circum-Pacific tectonic domain, metallogenic geo-logical condition of this area is superior. Besides, its regional metallo-genic characteristics are complex. Through the research on regional metallogenic geological background and the evolution of regional struc-ture in the West Ujimqin banner, the relationships between mineraliza-tion types and regional tectonic evolution are discussed. As the impor-tant ore-forming geological conditions and decisive metallogenetic fac-tors, the fault structure and magmatic activity control and determine the formation and spatial distribution of deposits and orebodies in the studied area.
