Precambrian crustal evolution in Rangrim Massif, Korean Peninsula

Petrological, chronological and geotectonic geological analysis of Precambrian metamorphic rock in Korean Peninsula shows that the remnants (>3.4 Ga) of continental nuclei crust were formed in the Paleoarchean in the Rangrim Massif. In the massif, the main formation ages of continental crust range from 3.2 Ga to 2.5 Ga, its important growing period was 2.8-2.5 Ga. The subsequent expansion period of the Rangrim Massif was 2.4-2.2 Ga. The division events occurred in 1.85 Ga and in the Late Paleoproterozoic- -Early Mesopro-terozoic, respectively. Since then the massif was relatively stable. However, the last division of the Rangrim Massif occurred at 793 Ma.
