Abstract: Focusing on the genetic relationship between the giant granitic zones and geotectonics, this paper have reviewed previous
researches about the assembly and breakup of global supercontinent, and summarized the research progress in the formation and
evolution of the Paleoproterozoic Columbia, Neoproterozoic Rodinia, Late Neoproterozoic-Early Paleozoic Gondwana and Late
Paleozoic-Early Mesozoic Pangea Supercontinents. Based on the geological data collected from major tectonic units in China (South
China, Tarim, North China blocks, Tibet, etc.), then we have a general understanding of the multiphases continental assembly and
breakup events, including their major features, diachronous evolution as well as the relationship to the formation and distribution of
giant granite belts and mineral resources. The significances of supercontinent cycling for the giant granite zones and the mineral
resources are discussed. In addition, some weak aspects in the previous researches are discussed, and perspectives for possible
innovations and breakthroughs in the coming future have also been proposed.

Key words: giant granite zone, global supercontinent, assembly-breakup, genetic relation, research expectation
