  • Middle Permian Brachiopods from Setamai, the Type Locality of The
    Sci. Rep., Niigata Univ., Ser. E(Geology), No. 16, 1-33, 2001 Middle Permian brachiopods from Setamai,the type locality of the Kanokura Formation,southern Kitakami Mountains, northeast Japan Jun-ichi TAZAWA* and Yosuke IBARAKI** Abstract A Middle Permian (Kubergandian-Murgabian) brachiopod fauna is described from the type section of the lower Kanokura Formation in the Setamai area, southern Kitakami Moun tains, northeast Japan. This fauna contains the following nine species: Transennatia gratiosa, Tyloplecta cf. yangzeensis, Waagenoconcha sp., Linoproductus cora, Cancrinella sp., Leptodus nobilis, Derbyia grandis, Derbyia nipponica and Spiriferella keilhavii. The Setamai fauna is characterized by the mixuture of both the Boreal and Tethyan elements. Key words: Boreal-Tethyan mixed fauna, brachiopods. Middle Permian, Setamai, southern Kitakami Mountains. Introduction The Permian brachiopod specimens described in this paper were collected by the authors and late Prof. M. Minato of Hokkaido University from nine localities in the Kanokurasawa and Kacchizawa valleys in the Setamai area, the type locahty of the lower part of the Kanokura Formation, southern Kitakami Mountains, northeast Japan (Figs. 1,2). The Middle Permian Kanokura Formation was named by Onuki (1937) as the Kanokura Stage, but Onuki (1956)later changed the name to 'formation' with the outcrops along the Kanokurasawa valley as its type section. The stratigraphy of the Kanokura Formation in the Setamai area was described and discussed in detail by Minato et al.(1954,1978,1979), Onuki (1956, 1969), Murata (1964), Saito (1966, 1968) and Choi (1973, 1976). In palaeontology, many species of fusulinaceans (Choi, 1973), corals (Minato, 1955; Minato and Kato, 1965), brachiopods (Hayasaka, 1953; Hayasaka and Minato, 1956; Minato and Nakamura, 1956; * Department of Geology, Faculty of Science, Niigata University, Niigata 950-2181, Japan ** Graduate School of Science and Technology, Niigata University, Niigata 950-2181, Japan (Manuscript received 24 November, 2(XX); accepted 21 December, 2000) J.

  • Brachiopods from the Mobarak Formation, North Iran
    GeoArabia, 2011, v. 16, no. 3, p. 129-192 Gulf PetroLink, Bahrain Tournaisian (Mississippian) brachiopods from the Mobarak Formation, North Iran Maryamnaz Bahrammanesh, Lucia Angiolini, Anselmo Alessandro Antonelli, Babak Aghababalou and Maurizio Gaetani ABSTRACT Following detailed stratigraphic work on the Mississippian marlstone and bioclastic limestone of the Mobarak Formation of the Alborz Mountains in North Iran, forty-eight of the most important brachiopod taxa are here systematically described and illustrated. The ranges of the taxa are given along the Abrendan and Simeh Kuh stratigraphic sections, located north of Damgham. The examined brachiopod species date the base of the Mobarak Formation to the Tournaisian, in absence of age-diagnostic foraminifers. Change in brachiopod settling preferences indicates a shift from high energy, shallow-water settings with high nutrient supply in the lower part of the formation to quieter, soft, but not soppy substrates, with lower nutrient supply in the middle part of the Mobarak Formation. Brachiopod occurrence is instead scanty at its top. The palaeobiogeographic affinity of the Tournaisian brachiopods from North Iran indicates a closer relationship to North America, Western Europe and the Russian Platform than to cold-water Australian faunas, confirming the affinity of the other biota of the Alborz Mountains. This can be explained by the occurrence of warm surface-current gyres widely distributing brachiopod larvae across the Palaeotethys Ocean, where North Iran as other peri- Gondwanan blocks acted as staging-posts. INTRODUCTION The Mississippian Mobarak Formation of the Alborz Mountains (North Iran) has been recently revised by Brenckle et al. (2009) who focused mainly on its calcareous microfossil biota and refined its biostratigraphy, chronostratigraphy and paleogeography.
