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.
