Abstract

Since "Gyeonsang Formation" has been introduced 90 years ago by B.Koto(1903), it was newly found within the lower Chomgog Formation ore mineralized zone. The mineralized zone occurs along the stratigraphic unit there. The ore minerals are mainly composed of hematite, ilmenite and magnetite. The molybdenum (2.100-3.100ppm?), copper and zinc are the accessories. There are also traces of cadmium, gadolinium, neptunium, ruthenium and tin. The ore mineralized zone shows about 1 km of apparent thickness with 10 to 12 degrees of plunging on the surface and extends 12 km along its strike in the U-Bo sheet(Chwae et al., 1990). The mineralized zone could be valuable to correlate the stratigraphic sequence between the Uisong and Mirryang subbasins, if giving consideration of the Palgongsan lineament (Chang, 1975).
