 note = {This study is focused on radiolarians from the Hirayu complex in the Nyukawa–Hirayu area, central Japan. The Hirayu Complex, which is a part of the Jurassic accretionary complex of the Mino Belt, is characterized by a melange including clasts of sandstone, felsic tuff, siliceous mudstone, red mudstone, chert, limestone and mafic volcanic rocks in a matrix of black mudstone and gray siltstone. Newly obtained radiolarians from this area constrain the age of black mudstone, gray siltstone, felsic tuff, siliceous mudstone and red mudstone as follows: black mudstone is Bajocian to Callovian, gray siltstone is Bajocian, felsic tuff is late Pliensbachian to Bajocian, siliceous mudstone is late Pliensbachian to early Aalenian and red mudstone is Toarcian in age. Radiolarians from chert in this study indicate Permian to Early Triassic, early Anisian of Middle Triassic and middle Sinemurian to early Aalenian of Jurassic in age. The radiolarians clearly show that the clasts of siliceous mudstone, red mudstone and chert are older in age than the melange matrix., 国立情報学研究所で電子化したコンテンツを使用している。},
