| 摘 要： | 花岗岩研究进入到新的时期,需要寻找新的研究思路和研究方法。本文总结了近十年来国际上有关花岗岩前沿研究的新进展,归纳总结了七个方面的主要研究内容,包括:1)地球早期花岗岩与大陆演化;2)源区的不均一性与不平衡熔融;3)岩浆成分变化的同位素示踪;4)壳-幔岩浆混合与花岗岩的形成;5)地壳热带与中酸性岩的形成;6)花岗岩岩体的生长和结晶时间;7)金属稳定同位素在花岗岩研究中的应用。最后在此基础上对花岗岩的研究趋势,建议利用新视角、新方法等着重开展花岗岩源区和岩浆深部过程的精细研究,并揭示花岗岩与早期地壳形成之间的联系。

| Abstract: | After about sixty-year studies on granitic rocks and especially the rapid developments on geochemistry and in situ zircon U-Pb and Hf-O isotopic analyses in recent decades, it is the time to find new research clues and methods to carry out further studies on granitoids. This paper summarizes the new progresses on the cut-edge studies of granitoids by domestic and international geologists in the recent decades. Seven main research topics are concluded: 1) granitoids of early Earth and continental evolution; 2) source heterogeneity and heterogeneous crustal melting; 3) isotopic tracing on variations of magmatic compositions; 4) mixing of crust- and mantle-derived magmas for petrogenesis of granitoids; 5) relationship between deep crustal hot zone and formations of intermediate to felsic rocks; 6) timescale of plutonic growth and crystallization; and 7) the applications of metal stable isotopes in the studies of granitoids. Based on the tendencies of current granite studies, it is suggested to carry out fine studies on source and magmatic processes of granites by new perspectives and techniques. The relationships between granite and the formation of earliest crust are also very important for future studies. |
