... with the Yeongnam massif, where relatively high V P / V S ratios of 1.78–1.82 are estimated. On the contrary, comparatively low V P / V S ratio measurements (1.71–1.76) are generally distributed in the Gyeonggi massif, which is located in the central area of the Korean Peninsula. The major factor for the high V P...

... The exposed Precambrian cratonic crust in South Korea is divided into two massifs the Gyeonggi massif to the north and the Yeongnam massif to the south. Mesozoic granites intruded into both massifs and are mostly I-types. The Jurassic granites form extensive deep-seated batholiths, the Triassic...

the emplacement of the Yeongdeok adakite, the arc magmatism was shut off in the Yeongnam Massif until the intrusion of the Macheon monzonite at 232 Ma. This reinitiation of magmatism was synchronous with the commencement of post-collisional magmatism in and around the Gyeonggi Massif. During or after
