概要介绍了北祁连山造山带造山之前的构造火山岩浆演化历史、成矿类型和成矿背景条件。文章指出：在北祁连山早古生代洋盆开合过程中，相伴发生的大规模海相火山作用和受海底热液循环体系制约的块状硫化物成矿作用，是该造山带地质历史发展中两个最鲜明的特色，也是该区地质研究中两个最为关键且互相关联的应当给以特别关注的领域。
The evolution history, metallogenic types and metallogenic background of tectonic volcanic magma before orogenic orogen in the North Qilian orogenic belt are briefly introduced. The article points out that during the process of the opening and closing of the Early Paleozoic ocean basins in North Qilian Mountains, the large-scale marine volcanism and the massive sulfide mineralization controlled by the seafloor hydrothermal circulation system are the two major geological processes in this orogenic belt The most distinctive features are also the two most crucial and interrelated areas that should be given special attention in the geological study of the area.
