Jurassic to Early Cretaceous accretionary complexes of Southwest Japan are widely distributed in the Mino, Northern Chichibu, and Southern Chichibu Belts. Tectonic history of each belt has been revealed for the last few decades especially by the progressions of radiolarian biostratigraphic studies. However, the detailed stratigraphy of the Northern Chichibu Belt was not established due to the small amount of radiolarian age data compared to those in the Mino and Southern Chichibu Belts. A highly resolved biostratigraphical dating of radiolarians in the Northern Chichibu Belt is necessary to determine its detailed stratigraphy. In order to get more precise information on the radiolarian age of the Northern Chichibu Belt, we reexamined the radiolarian ages of the Shimizu Formation, which is a part of the Northern Chichibu Belt. Kurimoto (1986) already reported the Late Carboniferous to Early Jurassic radiolarians from cherts and the Early to Middle Jurassic radiolarians from mudstones in the formation. However the amount of radiolarians found by Kurimoto (1986) in the formation is not enough to establish the detailed stratigraphy of the formation. As a result of our reexamination of the same rock samples used by Kurimoto (1986) and a newly obtained sample, more precise radiolarian ages were determined on the basis of newly identified radiolarian species.
