摘　　要：东升庙超大型多金属硫铁矿床为赋存于中元古界狼山群内的典型热水沉积矿床,形成于狼山—渣尔泰山中元古代裂陷槽构造环境。控制其形成超大型矿床的主要因素为:①有利的区域地质构造背景;②具高丰度成矿元素的矿源层;③封闭性极好的成矿环境;④同沉积期构造热事件的发生;⑤良好的保存条件。Dongshengmiao super-large polymetallic sulfur deposit is genetically hydrothermal sedimentation type, occurred in the Langshan group which located in the western part of northern margin of north China platform and formed in the Langshan-Zhaertai Mesoproterozoic Aulacogen tectonic environment. The systematic studies show the major factors leading to the Dongshengmiao super-large ore deposit as follows ： （1） the favorable regional geological structural setting; （2）the high abundance of ore-forming element in source bed;（3） the excellent sealing ability and stability of mineralization environment; （4）the tectonic-thermal event in the sedimentary mineralization process; （5）the excellent conservation conditions. The regularities which are obtained in this study can provide some new informations and ideas for the study of the geological structural conditions of mineralization of （super） large ore deposits.
