This study focuses on the lithology and radiolarian age of the Hidakagawa Sub-belt in the Shimanto Belt, Southwest Japan. The rocks of the Hidakagawa Sub-belt are divided into the Unit 1 consisting of only terrigenous deposits and Unit 2 consisting of terrigenous deposits with chert and red shale. The Unit 1 is subdivided into the Sub-unit 1A composed largely of thick-bedded sandstone with unknown age and Sub-unit 1B composed largely of late Albian to late Cenomanian sandstone-rich alternating beds of sandstone and shale. The Unit 2 is subdivided into the Sub-unit 2A composed largely of early Coniacian shale-rich alternating beds of sandstone and shale with mixed rock including sandstone, chert, and red shale, and Sub-unit 2B composed largely of latest Santonian to early Campanian thick-bedded sandstone with mixed rock including sandstone and red shale.<br/> On this basis of lithology, radiolarian age, and stratigraphic position, the Sub-units 1A and 1B are correlated to the Y3 and Y1 Members of Yukawa Formation in the central Kii Peninsula, and they can be correlated with the Ogui and Nagasaki Sub-units of Yukawa Unit in the coastal area of Kii Peninsula, respectively. The Sub-unit 2A and 2B correspond to the M1 and M2b Members of Miyama Formation in the central Kii Peninsula, and these sub-units can be correlated with the Karakozaki and Chidenohana Sub-units of Miyama Unit in the coastal area of Kii Peninsula, respectively.
