Lithostratigraphy and depositional environments of the Pyeongan Supergroup (Carboniferous–Permian) in the Taebaek area, mid-east Korea

“…Petrographic studies have been carried out in order to determine provenance and its tectonic implications (Lee, 1990a,b;Lee and Lim, 1995;Yu et al, 1997;Lee and Sheen, 1998;Ko et al, 1999). These studies suggest that sandstones of the Pyeongan Supergroup generally vary from quartzarenite to feldspathic litharenite and have few lithic fragments.…”

Albitization of feldspars in sandstones from the Upper Mesozoic Myogog Formation, Korea

“…Further, some of the quartz-rich sandstones are quartzitic in character (extensively cemented by silica cement), which may point to incipient metamorphism Ko et al, 1999 …”
