From the results of the CIA analysis (A-CN-K and A-CNK-FM ternary diagram), we concluded that granitic grus experienced low chemical alteration and contains plenty of sandy material The chemical alteration of Geochang and Gajo Basin advanced further than that of Yeongju-Bonghwa basin, but does not come to spatial differentiation as Chuncheon Basin. The weathered mantles of inner hills in the basin exhibit very weak alteration, and there is little spatial differentiation of chemical alteration between footslope of mountains, footslope hills. Most of hills are still in incipient weathering stage and have plenty of sandy materials. Therefore the chemical characteristics of granitic hills in Geochang and Gajo basin show that granitic weathered mantles are not saprolite formed by alteration but may be just grus (sandy weathered mantles).
