A sedimentary petrologic study was carried out to clarify the composition and textural properties of the Yuchi Conglomerate in the vicinity of Yuchi-rayon, Jangheung-gun The mean size of the clasts ranges from -3.2φ to -5.5φ. Most of the conglomerate in the area is classified as pebble conglomerate. Most of the clasts are subrounded to rounded, and discoidal and spheroidal clasts are ample. The clasts are mainly composed of andesite,rhyolite,granitic gneiss and tuff with some quartzite and vein quartz. 1t is assumed that depositional environment of conglomerates was fluvial environment. On the basis of sedimentological properties of conglomerates, the source area of the Yuchi Conglomerate seems to have been located to the north to northeast of the depositional basin.
