The Hiuchi outcrop is situated near Imajo town, Fukui Prefecture, where the geology belongs to Mino Terrane of the Inner Zone of Southwest Japan. Field observation showed that this outcrop consists of turbidity mudstone and sandstone alternation, shale, bedded siliceous shale, and bedded chert. Late Early Jurassic to early Middle Jurassic radiolarian fossils were obtained from a manganese nodule in the shale. SEM photographs of these radiolarians are presented.
