 note = {The Miyakoda Formation of the Chichibu Belt exposed in the Lake Hamana area, Sizuoka Prefecture, Chubu province, consists mainly of mélanges including slabs and blocks of chert and clastic rocks. Along the western coast of  Lake Hamana, a mélange including blocks of basalt, bedded chert, sandstone and alternating beds of sandstone and mudstone in a matrix of scaly mudstone is exposed. Radiolarian fossils were extracted from two samples (m-1 and m-2) from the  muddy  matrix. The radiolarian fossils such as Archaeodictyomitra (?) amabilis Aita, Eucyrtidiellum unumaense (Yao), Protunuma turbo Matsuoka, Stichocapsa japonica Yao, Stichocapsa robusta Matsuoka, Tricolocapsa(?) aff. fusiformis Yao sense Matsuoka, Tricolocapsa plicarum Yao and Unuma latusicostatus (Aita) were extracted from the mudstone of m-1. The radioalarian fossils such as Amphipyndax tsunoensis Aita, Eucyrtidiellum pustulatum Baumgartner, Eucyrtidiellum unumaense (Yao), Protunuma turbo Matsuoka and Sethocapsa zweilli Jud were extracted from the mudstone of m-2. Judging from the radiolarian fossils, the mudstone of the m-1 and m-2 are middle to late Bathonian in age. This fossil evidence indicates that formation of the mélange occurred after late Middle Jurassic time., 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。},
