Abstract

Metabasite lenses occur within granitic gneiss at Bibong in the southwestern part of the Gyeonggi massif, South Korea. Bibong metabasites experienced an initial eclogite facies metamorphism (17.0-20.9 kbar, 835°-860°C), which was succeeded by a granulite facies metamorphism (11.5-14.6 kbar, 830°-850°C) and finally overprinted by an amphibolite facies metamorphism (6.7-11.0 kbar, 570°-740°C). The metabasites have Sm-Nd internal isochron ages at 225-258 Ma, and the major elements of the metabasites display an island arc affinity. The petrochemical and geochronological data suggest the southwestern part of the Gyeonggi massif as an extension of the Triassic Dabie-Sulu collision belt in China.

Bibong metabasites experienced an initial eclogite facies metamorphism (17.0-20.9 kbar, 835°-860°C), which was succeeded by a granulite facies metamorphism (11.5-14.6 kbar, 830°-850°C) and finally overprinted by an amphibolite facies metamorphism (6.7-11.0 kbar, 570°-740°C).
