摘要
福建东南沿海变质岩的原岩时代长期未获解决。笔者采用 Sm-Nd 年代学技术,结合古生物成果,证明变质岩原岩时代为早古生代。在此基础上划分出平潭-南澳褶皱带并讨论其大地构造性质和意义。
The protolith age of the metamorphic rocks along southeast coast of Fujian province never has been solved for a longtime.By using the new achievements of the Sm-Nd isotopic chronology combined with the proofs on the palaeontology,wehave proved the protolith age of metamorphic rocks is the Early Palaeozoic Era.Basing it on,we bring forward the Ping-tan-Nan'ao folded belt and have discussed its geotectonic character and significance.
