| 摘 要： | 重点讨论了闽西南地区花岗岩类的同位素年龄和演化，将其划分为五期七个阶段，初步确定各阶段花岗岩类的岩石系列和组合及其与区域构造演化的关系。讨论了推覆构造与岩浆作用的关系，并认为与本区成矿作用有关的岩浆岩主要为两类花岗质岩石。研究区良好的矿源层和有利的赋矿层位以及海西期以来幔源岩浆的多次活动，使研究区成为十分有远景的成矿集中区。

| Abstract: | Based on the studying the isotopic ages and evolution of granitic rocks, granitic rocks canhe divided into five periods and seven stages. The relations hetween the rock series and associations of granitic rocks for various stages and the regional tectonic evolution are also indicated.According to the relation between the overthrust tectonics and magmatism two types of granitoid rocks were found to associate with the mineralization. The studying area can be regarded asa prospective mineralized area for stratigraphic units enriched metal sources and the favourableore-bearing layers as well as several magmatic activites since Hercynian period. |
