摘要
分布于粤北地区的以黄铁矿为主体的铅锌铜多金属矿床,尽管其地质和地球化学特点有一些差异,但仍具有一系列相似的成矿特点。它们的形成均经历了地台和地洼两个成矿阶段,并具有多成矿物质来源和多成矿作用方式的特点,它们构成了一个地台矿源层+地洼矿床叠加富集(及部分地洼活动改造富化)的多因复成矿床系列。其空间结构特点及分布规律严格受韶关—四会古断拉谷的生成、演化、运动和活化规律的控制。
Many polymetallic sulfides ore deposits occurring in northern Guandong possess a lot of similar metallogenic characteristics, although they have some differences in geological and geochemistrical features of mineralization. Their processes of formation experienced two metallotectonic stages, platform stages and diwa stages;and their ore-forming materials derived from several different sources. They ware composed of a polygenetic compound ore deposits series and were formed from platform-stage source bed + diwa-stage superimposing-richen-ing.regional distribution regularities are strictly controlled by the regularities of the formation,evolution,movement,and activiation of Shaoguan-Sihui ancient aulacogen.
