| 摘 要： | 文中首先从板块构造与大陆构造的对比出发,指出板块构造主要研究洋壳,洋壳主要研究玄武岩,玄武岩主要研究构造环境.大陆构造主要研究陆壳,陆壳玄武岩少花岗岩多,因此,花岗岩在大陆构造研究中具有特殊的地位.由于花岗岩比玄武岩复杂得多,其中尤以源岩和深度对花岗岩的影响最大,是大陆花岗岩研究最重要的课题.文中接着讨论了Sr和Yb的...

| Abstract: | Granitic rocks as the major component in the continental crust are particularly helpful to decipher the evolution of continental tectonics,which is quite similar in the way that basaltic rocks,being the major component of the oceanic crust,can be used to trace the tectonic settings in plate tectonics. Diversity of source rock composition and formation depth are two crucial factors controlling the compositions of resultant granitic rocks. It is proposed in this study that the variation of Sr and Yb contents ... |
