“…(1987) (Fig. 4), the investigated granitic rocks are classified as unfractionated granitic rocks, except for the Bulguksa granitic rocks in the central to western Ogcheon belt which have been described as fractionated granitic rocks (Lee et al ., 2010). In the Rb vs. (Y + Ta) diagram of Pearce et al .…”

“…5), the investigated granitic rocks plot in the field of volcanic arc granitic rocks, except for the Bulguksa granitic rocks in the central to western Ogcheon belt. Conversely, the Bulguksa granitic rocks in the central to western Ogcheon belt plot in the field of within plate granitic rocks (Lee et al ., 2010).…”

“…A negative Eu anomaly is seen in the Bulguksa granitic rocks in the central to western Ogcheon belt. This is due to the fractionation of plagioclase from the granitic magma (Lee et al ., 2010). Notably, the Eopyeong granitic rocks in the Ogcheon belt do not show a negative Eu anomaly and are adakitic.…”

“…As mentioned above, granitic rocks in South Korea are classified mainly into two types, based on their intrusion age; the Jurassic Daebo and Cretaceous Bulguksa granitic rocks. It is inferred that the Daebo granitic rocks were produced by subduction of the Farallon–Izanagi ridge, and that the Bulguksa granitic rocks were produced by oblique subduction of the Izanagi–Kula plate (Maruyama et al ., 1997; Oh et al ., 2004; Kim et al ., 2005; Lee et al ., 2010).…”

We investigated the Jurassic Daebo and Cretaceous Bulguksa granitic rocks in South Korea. The former are distributed mainly in the Gyeonggi and Yeongnam massifs and the latter are present in the Gyeongsan basin and Ogcheon belt. The Daebo granitic rocks generally are of ilmenite series and I to S type. These rocks are associated with Au-Ag hydrothermal deposits, whereas the Bulguksa granitic rocks are of magnetite series and I type, and are associated with Pb-Zn, Cu and Mo-W hydrothermal deposits, as well as Au-Ag hydrothermal deposits. The Daebo granitic rocks show adakitic signatures in their chemical compositions. They are considered to have been derived from partial melting of the thick lower continental crust. Conversely, the Bulguksa granitic rocks in the Gyeongsan basin are non-adakitic and are considered to have been derived from partial melting of a mantle wedge. Magmas of the Daebo granitic rocks formed at relatively shallow levels, but solidified at deep levels compared with those of the Bulguksa granitic rocks. The Bulguksa granitic rocks in the central to western Ogcheon belt are considered to have been formed by fractionation of magmas derived from partial melting of continental crust. The total Al contents of biotite and hornblende in the granitic rocks increased, with the Bulguksa granitic rocks in the Gyeongsan basin < the Bulguksa granitic rocks in the Ogcheon belt and Gyeonggi and Yeongnam massifs and the Daebo granitic rocks in the Ogcheon belt < the Daebo granitic rocks in the Gyeonggi and Yeongnam massifs. This order corresponds to an increase in solidification depth.

“…Recently, a large amount of data have been gathered from studies related to the Yanshanian magmatism in the eastern part of the NCC (Zhang, 2007;Gao et al, 2008), with several workers correlating the process with lithosphere thinning (Shao et al, 2000(Shao et al, , 2007Li et al, 2004bLi et al, , 2006Li et al, , 2007bXu et al, 2004;Huang and Zhao, 2006;Zhang, 2007;Xu, 1999Xu, , 2007Huang et al, 2007;Kusky et al, 2007;Cope and Graham, 2007;Gao et al, 2008;Xu and Zhao, 2009;Zhao, 2009;Lee et al, 2010;Li et al, 2011). However, the detailed mechanism and tectonic setting related to the lithosphere thinning are significantly different.…”
