Abstract
The stratigraphy of the Osaka Group in surveied area is as follows; [table] This stratigraphy is well accorded with that of the other hills which made of the Osaka Group; for example, Senriyama,Ibaraki and Hirakata Hills. Tomistoma sp. and many plant fossils yielded in this area as shown in Table 2. The paleocurrent directions deduced from cross beddings and inclination of gravels were obtained. The results are summarized in Figs. 9 and 10. Paleocurrent directions are clearly divided into two groups ; that is, from northeast to southwest and from southeast to northwest. The former may be products of the ancient river Akuta and the latter may be from the ancient river Yodo. These two directions are found at same cliff in several places.
