摘要
志留纪之后，秦岭佛坪古陆就同白水江古岛一样横亘于古秦岭海洋之间。在南北两大板块的历史演化中，它从早期的热异常发展到热柱隆起，直至岩浆的形成与侵入。在这个漫长的过程中，它不仅影响着造山过程，还对周边盆地及金属矿床的形成、演化具有重要意义。研究了佛坪古陆的热事件及对周边盆地的影响，探讨了陕西沉积岩容矿金属矿床的形成与演化。
After Silurian, the Fuping ancient land and the Baishuijiang ancient land were located in the Qinling ancient ocean. in the evolution history of two plates in north and south, two ancient lands developed from early thermal abnormaly, though thermal plume rising to intrusion of magma, which not only affected orgogen process but also affected their neighbouring basins and had significance for the formation of metallic deposits. The importance should be attached to the study on thermal events and its affection on the neighburing basins for studying formation of metallic deposits hosted in the sedimentary rocks. Thus, it can guide the prospecting work.
