| Abstract | 运用野外地质、分析测试、高温高压实验等手段对长乐－南澳带的性质进行了重新框定；对该带的大地构造，地球化学演化提出了系统且新的认识；高温高温实验及元素分配研究为研究区地质地球化学演化研究提出了一些重要的启示，首次在研究区进行高压下岩石弹性波速实验研究，并讨论了影响岩石波速的诸多因素；通过石英中流体包裹体的研究将变质流体分为三期并讨论了其性质及演化。 |
| Other Abstract | Geology and geochemistry studies are systematically carrid out on Changlo-Nanao deformation-metamorphism zone by methods of field geology, analyse determination, high-temperature and high-pressure experiment. On the basis of past geology work, both in field and in miroscope, it can be concluded that the south-east coast region of Fujian(Changlo-Nanao) is a plate margin metamorphism zone and also a structural deformation (ductile-shear) zone. But it is most appropriate to call this zone as "deformation-metamorphism zone". Deformation-metamorphism rocks may be divided into 3 types of petrochemistry (positive, negative and transitive metamorphic rocks). The variation of petrochemistry is closely related to metamorphic degree and has nothing to do with positions. The part melting, experiments of high-temperature and high pressure show themelttemperature of rock increases according to the increasing of metamorphic degree, pressure, the contents of FeO*+MgO+CaO+TiO and the decreasing of K+Na. |
