| 内容記述 | In this study, for the first time, a poorly developed trace fossil assemblage from the Lower Miocene Akahotani Formation is analyzed. This was cropped out of an excavated wall of the Nishiyama Quarry Remains at Takigahara, western Komatsu, in central Japan. The Akahotani Formation is mainly composed of non-fossiliferous greenish grey tuff related to intensive volcanic activities during the opening of the Sea of Japan from the Oligocene to middle Miocene Epochs. The trace fossils were yielded from pale-colored coarse-grained tuff and overlying dark-grey muddy fine-grained tuff layers. Both were intercalated with greenish-grey lapilli tuff called “Takigahara-ishi” which is used in construction materials. The assemblage consists of deposit-feeding burrows filled with grey muddy fine tuff, specifically phycosiphoniform and Planolites. Both of them are sub-grouped into large and small morphospecies. Vertical modes of occurrences of phycosiphoniform are characterized by small clusters containing sparsely distributed, indistinct cores (U-shaped, streak- and dot-like morphologies) with or without very pale mantles. Planolites exhibit circular, elliptical and slightly curved, horizontal pellet-like configurations in the vertical section. The large form of phycosiphoniform sometimes cross-cuts the small phycosiphoniform and Planolite burrows. The occurrence of phycosiphoniform strongly indicates the Akahotani Formation at least partly experienced under marine condition which is significant because it reveals the sedimentary facies and benthic paleoecology of this pyroclastic deposit. |
