摘要
在对福建地区最新的地质、地球物理、地球化学成果进行综合研究认为 :1.福建境内壳幔的成分有在时间上随不同构造期而演变的趋势。2 .地幔作用的活动区有在空间上随不同构造期而迁移的趋势。 3.岩石圈内的拉张和挤压作用在时间上交替发生 ,在空间上则于相邻地块间呈反向对应互补性。 4 .岩石圈处于拉张为主时 ,地幔作用活跃 ,形成以亲铁和亲硫的铁、铜、金、铅、锌、银等金属矿床为主 ;岩石圈处在挤压状态时 ,以地壳作用为主 ,形成亲氧的钨、锡、稀有。
Based on the comprehensive results of geology, geophysics and geochemistry, it is inferred that (1)there is a composition evolutive trend in the different structure stage of the crust-mantle within Fujian Province; (2)there is a migrant trend of the different stage of active mantle regions in space; (3)the interchange of compression and extension in the lithosphere takes place in time and occurs the inverted correspond complementarity in the adjacent massifs in space; (4) in the extension environment of the lithosphere the mantle activity results in forming siderophile and thiophile metalliferous deposits of copper, gold, led, zinc and silver, and in the extension environment of lithosphere the active crustal movement brings on forming the oxytropic metalliferous deposits of tungsten and tin, rare and rare-earth elements.
