本文全面论述在长江中下游成矿带中的铜陵地区,首次发现石炭纪海底火山喷发——沉积的火山岩系列及与它有成因联系的黄铁矿型铜矿。从成矿理论上提出断裂拗陷型的海底火山喷发——沉积黄铁矿型铜矿的特征及成矿后的变化,指出了迭生成矿作用的过程和意义,为在长江中下游普查铜矿提出了新的方向。 This paper comprehensively discusses the Tongling area in the metallogenic belt in the middle and lower reaches of the Yangtze River. It is the first time that the Carboniferous submarine volcanic eruption-sedimentary volcanic series and the pyrite-type copper deposit associated with it have been discovered. Based on the ore-forming theory, the authors put forward the characteristics of submarine volcanic eruption-sedimentary pyrite type copper deposits and their changes after ore-forming, and point out the process and significance of the superimposed mineralization. In the middle and lower reaches of the Yangtze River, Mine proposed a new direction.
