The strata which have been referred to the Permian are divided into the following three Formations in ascending order ; 1) the Lower to Middle Permian Mizuyagadani Formation (redefined), 2) the Middle Permian Sorayama Formation (redefined), and 3) the age-unknown Kashiate Formation (newly named). The Mizuyagadani Formation, composed mainly of felsic tuff, clastic rocks, and tuffaceous clastic rocks, is subdivided into the Lowermost, Lower, Middle, and Upper Members. Although this formation is in fault contact with the Carboniferous Ichinotani Formation, it is inferred that the former primarily overlies the later based on the field evidence. The Sorayama Formation, composed mainly of mafic to intermediate tuff breccia and tuffaceous clastic rocks, is subdivided into Member A to D in ascending order. This formation conformably overlies the Mizuyagadani Formation. The Kashiate Formation, composed mainly of mafic igneous rocks and breccia including clasts largely of basalt to gabbro, is thrust over the Sorayama Formation. Although the three conglomerates exposed in the upper stream of the Ichinotani and Mizuyagadani Valleys and Osobudani Valley were dealt with as the basal conglomerate of the Sorayama Formation previously, these conglomerates are considered to be on the different lithostratigraphical units of the Mizuyagadani Formation and "undivided strata., 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。}, pages = {1--35}, title = {Redefinition of the Permian strata in the Hida-gaien Tectonic Zone, Fukuji area, Gifu Prefecture, Central Japan}, volume = {47}, year = {2000} }
