We have elucidated the ages of these horizons on the basis of radiolarian biostratigraphy in seven onshore sections of Akita Prefecture. Age of the last occurrence of S. compressa is determined as 5.4 Ma, while that of the first occurrence of M. echigoensis as 5.2 Ma. We further reexamined the biostratigraphic ages of published data regarding cores from the deepest part of the Sea of Japan obtained by ODP Legs 127/128. The results are consistent with the ages which we obtained. Furthermore, these determined ages are close to the age of the Miocene / Pliocene boundary, 5.32 Ma. Therefore these foraminiferal biohorizons are significant in recognizing the Miocene/Pliocene boundary in the Sea of Japan region.Based on compilation of previous studies, the upper depth limit distribution of S. compressa is assumed to have been deeper than the Lower Middle Bathyal Zone, and than that of M. echigoensis from the Middle Bathyal Zone to the deepest part, which indicates their overlapping paleobathymetric ranges. Our compilation also indicates that S. compressa occurred preferably in strata deposited under a suboxic paleoenvironment, while M. echigoensis under an oxic one. Consequently, the disappearance of S. compressa and subsequent appearance of M. echigoensis suggest a change of the bottom water condition in the Sea of Japan. This paleoenvironmental change was presumably caused by the post-Messinian raised sea level in the earliest Pliocene, which enhanced the exchange of seawater between the Pacific and the Sea of Japan."},{"@value":"秋田県内の7ルートにおいて放散虫化石層序を検討した結果, 底生有孔虫化石Spirosigmoilinella compressaの産出上限の年代として5.4 Ma, Miliammina echigoensisの産出下限の年代として5.2 Maを得た.さらに, ODP Legs 127/128の公表資料について各サイトの年代層序を再検討し, S. compressaの産出上限の年代と, M. echigoensisの産出下限の年代を調査した結果, 秋田地域で得られた年代値と整合的であることが明らかとなった.両種の入れ替わる年代は中新世・鮮新世境界の年代(5.32 Ma)と接近しており, 同地域における中新統・鮮新統境界を認定する上で大変有効である.既存資料に基づいてS. compressaとM. echigoensisの生息深度を推定した結果, 両種の生息深度は互いに重複し, 日本海最深部に及ぶことが判明した.これら2種の日本海地域における入れ替わりは鮮新世初期の汎世界的な海水準上昇に起因する日本海底層水環境の変化に対応すると推測される."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001206233755778","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000004608578"}],"foaf:name":[{"@language":"en","@value":"Hanagata Satoshi"},{"@language":"ja","@value":"花方 聡"}]},{"@id":"https://cir.nii.ac.jp/crid/1420001326235873792","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"80295295"},{"@type":"NRID","@value":"1000080295295"},{"@type":"NRID","@value":"9000259324129"},{"@type":"NRID","@value":"9000405091842"},{"@type":"NRID","@value":"9000002546641"},{"@type":"NRID","@value":"9000001748511"},{"@type":"NRID","@value":"9000401964410"},{"@type":"NRID","@value":"9000004299772"},{"@type":"NRID","@value":"9000327448643"},{"@type":"NRID","@value":"9000405091856"},{"@type":"NRID","@value":"9000368405036"},{"@type":"NRID","@value":"9000257860466"},{"@type":"NRID","@value":"9000413534238"},{"@type":"NRID","@value":"9000413534242"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0066692"}],"foaf:name":[{"@language":"en","@value":"Motoyama Isao"},{"@language":"ja","@value":"本山 功"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282681210272641","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Miwa Michiko"},{"@language":"ja","@value":"三輪 美智子"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00167630"},{"@type":"EISSN","@value":"13499963"},{"@type":"CODEN","@value":"CHTZA5"},{"@type":"NDL_BIB_ID","@value":"000000014674"},{"@type":"ISSN","@value":"00167630"},{"@type":"LISSN","@value":"00167630"},{"@type":"NCID","@value":"AN00141768"}],"prism:publicationName":[{"@language":"en","@value":"The Journal of the Geological Society of Japan"},{"@language":"ja","@value":"地質学雑誌"},{"@language":"en","@value":"Jour.
