N2  - In the Maizuru zone nearly whole the Triassic successions are developed. The Scythian to Aniso-Ladinian strata make a continuous sequence, in which are distinguished three faunizones, Neoschizous-"Bakevellia", Hollandites-"Danubites" and Monophyllites, corresponding to Scythian, lower Anisian and Aniso-Ladinian, respectively. Main portion of the Ladinian series is lacking in this region. The earliest Carnian or Ladino-Carnian Arakuran age is newly proposed founded on the palaeontological and stratigraphical studies on the Arakura formation. In the next Sakawan (not Carnian) Nabae group, two and probably one more, faunizones are recognizable, Palaeopharus-Lima yataensis, Tosapecten-Pseudolimea, and Pleuromya-Neoschizodus. The Sakawan age is classified into two subages better than the three formerly proposed by K. ICHIKAWA. The Norian sediments are probably represented by the Nakaiso conglomerate bed, although barren in fossil. The Rhaetic strata are not found at all like other regions in Japan. From the facies-analysis, the Palaeo-Maizuru Bay during the Scythian to Aniso-Ladinian epochs and the Palaeo-Maizuru Inland Sea during the Carnian epoch are assumed. Finally, the orogenic history of the Triassic period in this zone is briefly stated.
