事件地质激发成矿作用异常与超巨量金属工业堆积

Event Geology Stimulating Anomalous Ore-Forming Processes with Economic Super-Accumulation of Metals

本文提出成矿学中的事件地质,系指在成矿历史演化进程中发生的地质事件激发正常成矿作用异常形成超巨量金属工业堆积和特大型矿床。重点探讨跨区域壳幔结构不连续性、幔根构造的形成和构造圈热侵蚀事件与成矿,并列举美国西部有色金属成矿区和中国南岭钨锡多金属矿集区与幔根构造有关地质事件形成超大型矿床的实例。

Event geology in metallogeny refers to anomalous geological events in the evolutional processes of metallogenic history that stimulates normal ore-forming processes to promote the economic super-accumulation of metals and exceptional super-large deposits to formed. The key contents of this paper are to discuss the for discontinuity in the crust-mantle structure in trans-region, formation of mantle-rooted structure and events of tectonosphere thermal erosion with metallogeny,, as well as living examples on the metallogenic areas of nonferrous metals in the western U. S. A. and mineral assemblage area of tungsten-tin poly-metallic metals in NaMing, China.
