摘要
通过对粤西罗定地区构造演化及成矿演化探讨分析,确定地壳经历了地槽发展阶段(新元古代—早古生代)、准地台发展阶段(泥盆纪—中三叠世)和大陆边缘活动带阶段(晚三叠世—全新世)三个大地构造演化阶段。区域地质演化三个阶段对区域多金属矿成矿有着特别意义,总体上呈现成矿元素初始富集—预富集—工业富集递进作用特征。
Through the discussion and analysis on tectonic evolution and metallogenic evolution of Luoding region in the west of Guangdong Province,the paper determines the earth＇s crust has passed three major stages of tectonic evolutiongeosycline stage of development（Neoproterozoic-early Paleozoic）,paraplatform stage of development（Devonian-middle Triassic）,and continental margin active belt stage（late Triassic-Holocene）.The three evolution stages of regional geological evolution have special significance for polymetallic ore mineralization in this region.In general,it presents characteristics of progressive function of initial enrichment of ore-forming elements—pre-enrichment—industrial enrichment.
