摘　　要：本文通过对抚顺浑南地区区域地质构造发展演化阶段和地质事件分析,确定本区地壳具有多旋回演化的特点,经历了中朝准地台结晶基底形成阶段(太古代—早元古代)、地台稳定盖层发展阶段(中元古代—中三叠世)和大陆边缘活动带发展阶段(晚三叠世—新生代)三个大地构造演化阶段;依据区内各矿床成矿地质条件、矿产类型、同位素年龄资料的研究,对各成矿时代的成矿作用进行了归纳和探讨,确定区内有3个主要成矿期,这一新的认识对指导找矿具有重要意义。In this paper,Fushun Hunnan Regional stage of development and evolution of geological structures and geological event analysis to determine the evolution of the crust with a multi-cycle characteristics of quasi-Sino-Korean platform has experienced the formative stages of the crystalline basement（Archean-Early Proterozoic）,Platform stability and caprock development stage（Mesoproterozoic Era-Middle Triassic） and the continental margin activity belt development stage（Late Triassic-Cenozoic） tectonic evolution of three stages;based on regional metallogenic geological conditions,isotopic age data,The research on the ore-forming age of mineralization is summarized and discussed to determine the area has three main ore-forming periods,this new understanding has a great significance in guiding the exploration.
