| 摘 要： | 花岗岩的起源、形成的物理化学过程、结晶和分异、矿物-化学成分多样性、时空演变等是当前花岗岩研究的主题.矿物微区原位同位素分析,特别是锆石原位微区U-Pb和Hf-O同位素分析,以及岩浆作用的物理过程实验模拟是重要的研究手段.近年来,不同类型花岗岩起源和演化过程认识的深入,得益于对与花岗岩及其伴生的其它相关岩石研究的突破,以及锆石原位U-Pb和Hf-O同位素分析技术的应用.本文结合国内外花岗岩研究进展,综述了我国东南部华夏陆块上花岗岩研究中的一些问题.

| Abstract: | The main themes of current granite studies include the origin of granitic magmas,physical and chemical processes in their formation,crystallization and differentiation in their evolution,chemical-mineralogical varieties and spatial-temporal evolution of the magmas.The key approaches in granite studies are in-situ isotope measurements,especially the in-situ isotope measurements of U-Pb,Lu-Hf and O isotopes in zircons,and experimental modeling of physical processes of magmatism.Benefit from comprehensive studies of granites and genetically related other rocks and by application of in-situ analyses of U-Pb,Lu-Hf and O isotopes in zircons,a great progress has been achieved recently in better understanding of the origins and the magmatic processes of granites.On the basis of the new progresses of granite studies,this paper tentatively discusses the petrogenesis of granites in the Cathysia block of southeastern China. |
