| 摘 要： | 鲁西陆块是中国前寒武纪研究的热点地区之一,其前寒武纪花岗岩-绿岩带地体的划分与构造演化历来为学者们注目。通过系统收集近年来鲁西陆块前寒武纪SHRIMP U-Pb测年数据,利用鲁西陆块前寒武纪花岗岩类岩石化学数据判别其形成的构造环境,综合国内大地构造相方面的研究成果,并在此基础上得出:鲁西陆块前寒武纪地壳形成与演化主要经历了中太古代-陆核形成阶段、新太古代-陆壳增生阶段、元古宙-大陆裂解阶段3个阶段。

| Abstract: | Luxi landmass is one of the hot areas for studying Precambrian in China. Division and tectonic evolution of Precambrian granite greenstone belt terrane have always been paid more attention by scholars. In recent years, through systematic collection of Precambrian SHRIMP zircon UP-b dating data of Luxi landmass, by using chemical data of Precambrian granite rocks in Luxi landmass, tectonic environment of its formation has been discriminated. In this paper, tectonic research results in China and abroad have been summarized comprehensively. On this basis, formation and evolution of Precambrian continental blocks in Luxi crust have experienced three stages, they are Archean continental nucleus formation stage, Neoarchaean-continental crust accretion stage and Proterozoic-continenetal breakup stage. |
