“…Further the results of recent studies also have raised a possibility that the middle part of the Korean Peninsula might be a part of the South China Craton (Ree et al, 1996;Kwon et al, 1997;Qiu et al, 2000). On the contrary, Cluzel et al (1991) suggested that the southern part of the Korean Peninsula had been a part of the Sino-Korean Craton before the early Triassic. Based on petrography and Rb-Sr isochron age data, Adachi and Suzuki (1993) suggested that the Precambrian gneissic clasts in the Kamiaso conglomerate, Japan, could be derived from the eastern Korean Peninsula (Sobaegsan Massif).…”

The Precambrian basement of the Korean Peninsula, located at the east margin of Asian continent, consists of the Nangrim Massif, the Gyeonggi Massif and the Sobaegsan (Yeongnam) Massif. Two kinds of orthogneisses (biotite gneiss and granitic gneiss) from the central part of the Sobaegsan Massif show the particular difference in geochemical features suggesting the discrimination in formation history. The biotite gneisses give an Sm-Nd whole rock isochron age of 819 ± 114 Ma (2σ) with ε Nd (0.82 Ga) = -15, and the granitic gneisses give an age of 1484 ± 810 Ma (2σ) with ε Nd (1.48 Ga) = +7. The ε Nd and ε Ce values for the granitic gneisses show characteristics of highly depleted mantle material and those of the biotite gneisses show their sources having light-REE enriched continental-like feature. Chondrite-normalized REE patterns are also different. Biotite gneisses have less fractionated patterns with (La/Yb) N ratio of 10~16 and negative Eu anomalies, while granitic gneisses have fractionated patterns with (La/Yb) N ratio of 30~180 with no/or positive Eu anomalies. The Ce-Nd isotopic results obtained here indicate that the Sobaegsan biotite gneisses were derived from continental-like sources having light-REE enriched feature, while the Sobaegsan granitic gneisses were derived from MORB-like sources having light-REE-depleted feature. These isotopic and REE data are interpreted as recording LREE fractionation events associated with major episodes of crust formation in East Asia. And the comparison of the initial ε Nd value of the Sobaegsan biotite gneiss at 0.82 Ga with those of the Chinese and Japanese Precambrian rocks implies that the sources for the Sobaegsan biotite gneisses and these Chinese and Japanese rocks had common light-REE enriched pattern, e.g., 147 Sm/ 144 Nd ratio ranging from 0.09-0.13. Furthermore, it suggests that these sources having light-REE enriched patterns were derived from depleted mantle at the late Archean.

Recently developed illite-age-analysis (IAA) approach has been applied to determine the multiple events for the Singal and Wangsukcheon faults in the Chugaryeong fault belt, Korea. Fault reactivated events during Late Cretaceous to Paleogene events(69.2±0.3 Ma and 27.2±0.5 Ma) for the Singal fault and of 75.4±0.8 Ma for the Wangsukcheon fault were determined by combined approach of the optimized illite-polytype quantification and the K-Ar age-dating of clay fractions separated from the fault clays. These absolute geochronological determinations of the multiple tectonic events recorded in the Chugaryeong fault belt are crucial to establish the tectonic evolution of the Korean Peninsula since Late Cretaceous.
