摘要
成矿是一种复杂的地质作用,区域构造与区域地球化学是控制成矿的基本要素。文中简略叙述了构造成矿研究的历史,论述了大型构造与成矿的关系,提出构造动力体制转换是引发成矿作用的一种重要机制。通过对我国矿田构造研究的回顾,总结提出构造研究的一些思路,同时对区域地球化学与成矿、上地幔元素丰度与成矿以及地球化学急变带与成矿等做了简要的讨论,认为岩石圈及地质体中一定含量的金属元素是成矿的必要条件,而成矿尚需一定的地质作用对这些金属元素的浓集。
Ore formation is one of complex geological processes.Regional structure and regional geochemistry are two basic ore-controlling factors.In the paper, a brief history of structural ore-formation is reviewed; the relationship between microscopic structures and metallogeny is discussed.The author put forward that transformation of structural tectonic systems is one of the most important mechanism, which can induce the occurrence of ore-formation.Also the relationships between regional geochemical blocks and metallogeny, and between abundant of elements in upper mantle and metallogeny, and between geochemical steep zone and metallogeny are curtly discussed. The metallic elements with certain abundance in lithosphere and geological bodies are the precondition of ore-formation, while metallogeny need some special geological processes to concentrate the metallic elements further.
