Abstract :We examined the Miocene Iwaine Formation formed in the margin of the Eurasian continent during the Japan Sea opening, of the Yatsuo Group in the Yatsuo area located in Toyama Prefecture, central Japan, on the basis of lithology and stratigraphy. The Iwaine Formation is composed mainly of monomictic autobreccia, polymictic volcanic breccia, pumice tuff and coherent andesites, with clastic rocks whose clasts were derived from the Iwaine Formation, in stratigraphically ascending order. Lithostratigraphy of the Iwaine Formation in the Yatsuo area will be of great significance to reveal the characteristics of volcanism during the Japan Sea opening.
