This study is conducted in order to investigate the stratigraphy of the Cretaceous sedimentry rocks, trending NS and NNE-SSE, which is distributed in the Neungju Basin located in Jangseong-Sinangun Jangsando, Damyang-Hwasut~Jangheunggun Daedog, Gurye-Seungjugun Songchijae-Seungjugun Haeryong. The result of this study are as follows: 1. Bed rocks in study area are composed of gneisses, schists, quartzite, shistose granite and granite ; sedimentary rocks are mainly tuff, shale, sandstone and conglomerate in ascending order igneous rocks are andesite and rhyolite. The reddish shale and sandstone are alternated, and conglomerate are polygenetic ones in all Iocalities except Jangheunggun Daedog localities. 2. The stratigraphy of the study area can be expressed as Bed rocks, Ingog tuff, Seoyuri formation, Jangdong tuff, Uchi conglomerate, Dado tuff and Mudeungsan volcanic rocks in ascending order. 3. The geologic age of sedimentary rocks in the study area is upper Cretaceous and correlated with the Yucheon Formation of the Gyeongsang Supergroup
