The East Java Basin is extensively filled with carbonate\nand siliciclastic sedimentary rock since Eocene. Several studies exhibit comprehensive\nexplanation of the depositional system of the East Java Basin during Cenozoic, most of\nthe age of the sedimentary rock has not been well-dated and only a few researchers had\nconduct precise age dating. Biostratigraphy of several exploration wells in the East Java\nBasin also had been studied for both planktic foraminifera and calcareous nannofossil\nby. However, the areas studied are limited and some of the results have not indicated\nthe high resolution. Based on that problem, the calcareous nannofossil biostratigraphy\nof LSM-1, JTR-1, BEL-1, TPN-1, KTB-1, and NGB-1 wells located in the onshore East\nJava Basin, Indonesia was studied in detail to clarify the age distribution of sedimentary\nrocks and the history of basin evolution of the onshore East Java Basin.\nTotal of 678 cutting samples was selected every 20m interval and processed using\nthe smear slide preparation method. All smear slides were examined under an Olympus\nbinocular polarizing microscope and quantitative analysis was employed. Graphic\ncorrelation also applied to derive precise biostratigraphic correlation.\nA total of 71 species from 26 genera of calcareous nannofossil were determined\nin the seven wells, most of the specimens are found at moderate to good preservation.\nReworked specimens from early Miocene series are sometimes observed in the Pliocene\nseries. The age assignment based on 27 calcareous nannofossil datum were obtained as\nfollow: DDR-1 corresponds to NN3-NN15 of the early Miocene to the early Pliocene.\nNGB-1 are appointed to NP23 to NN7 of the early Oligocene to the late Miocene. KTB-\n1 is assigned to NP25-NN16 of the late Oligocene to the late Pliocene. TPN-1 covers\nNN7-NN16 of the middle Miocene to the early Pliocene. BEL-1 is estimated as NN3 to\nNN5 of the early to middle Miocene. of JTR-1 is assigned to NP23-NN4 of the early\nOligocene to early Miocene. And the last, LSM-1 is estimated corresponding to NP25-\nNN16 of the late Oligocene to early Pliocene.\nThe result from the biostratigraphic correlation analysis indicates that a total of\nfour significant unconformities are traceable in the sequence between the Oligocene and\nthe Pliocene in this area. The Oligo-Miocene Unconformity (OMU) is situated in the\nOligocene/early Miocene boundary. The OMU, which is traceable to all wells, is\ncharacterized by the missing of the interval from NN1 to NN3 zone of the early Miocene.\nThe Mid-Miocene Unconformity (MMU) is correlated to the early-middle Miocene\nwhich is found only in KTB-1 and NGB-1, since the calcareous nannofossil zone of\nNN6 is not present in these wells. The late Miocene Unconformity (LM1), which is\ncharacterized by the missing of the interval NN8 of the early late Miocene is traceable\nto KTB-1, DDR-1, and TPN-1. The Mio-Pliocene Unconformity (MPU), which is the\nbiggest unconformity found in the study area, is situated in the lower Pliocene base. In\nthis area, the lower Pliocene NN14 sediment is distributed above the MPU. The time\ngap of the MPU is the biggest in LSM-1 and BEL-1 located in the north western area.\nThe interval, NN6 to NN13 of the middle Miocene to the lowest Pliocene is missing in\nLSM-1, and NN8-NN13 is also missing in NGB-1.\nBased on the bio-lithostratigraphic correlation analysis, the results indicate that\nthe sediment above the OMU is situated relatively in the centre of the studied area (BEL-\n1 and TPN-1). In contrast with sediment of the Miocene above the MMU and LM1\nwhich are concentrated in the central to south-southeast area, the location of Pliocene\nsediment above the MPU moves to the north and north-western area. The depositional\npattern also demonstrates that the majority of sandstone and limestone deposition is\nlinked to the distribution of unconformities, which are located just above them. During\nthe middle to late Miocene, there is no evidence of sedimentation in the north and\nnorthwest. The thickest sandstones, which are reservoir rocks of this oil field, is\ncorrelated to the early Pliocene Low System Tract and Transgressive System Tract\nabove the MPU.\nThe stratigraphic series and unconformities detected in the study area show a good\ncorrelation to the global climatic events and tectonic evolution. The Oligocene Series is\ncorrelated to the late Oligocene warm event. The Miocene Series unconformably overlie\nthe Oligocene Series and fit to the Mi 1 cooling event. The early Miocene series above\nthe Oligo-Miocene Unconformity is correlated to the Mid-Miocene climatic optimum\nevent. The Mid-Miocene Unconformity may be correlated to the cooling events Mi3 or\nMi4 just after the Mid-Miocene Climatic Optimum. The middle-late Miocene sequence\nbetween the Mid-Miocene Unconformities and the Late Miocene Unconformity 1 is\nconsidered a single transgressive-regressive cycle. The Late Miocene Unconformity 1\nis correlated to the cooling event of Mi5. The Mio-Pliocene Unconformity is correlated\nto the Messinian Salinity Crisis event and RMKS Uplift. The upper-lower Pliocene\nseries above the unconformity is correlated to the mid-Pliocene Warm Period. These\nresults indicate that the stratigraphic evolution and formation of the unconformities\ndetected in the East Java Basin during upper Cenozoic are strongly influenced by\neustacy sea-level changes, and then by tectonics, especially in the late Miocene to the\nQuaternary.","subitem_description_type":"Other"}]},"item_10006_dissertation_number_42":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙第660号"}]},"item_10006_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20569/00006115","subitem_identifier_reg_type":"JaLC"}]},"item_10006_publisher_28":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"秋田大学"}]},"item_10006_version_type_35":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"RENDY"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-06"}],"displaytype":"detail","filename":"shihakuyoushiotsu660.pdf","filesize":[{"value":"194.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"内容要旨及び審査結果要旨","url":"https://air.repo.nii.ac.jp/record/5803/files/shihakuyoushiotsu660.pdf"},"version_id":"3b25867d-06af-4d16-8f8c-f0d9fef7d072"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-12-06"}],"displaytype":"detail","filename":"shihakuotsu660.pdf","filesize":[{"value":"51.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://air.repo.nii.ac.jp/record/5803/files/shihakuotsu660.pdf"},"version_id":"0dc48280-9ea6-4638-816d-21d6bdb4ff83"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Calcareous Nannofossil","subitem_subject_scheme":"Other"},{"subitem_subject":"Biostratigraphy","subitem_subject_scheme":"Other"},{"subitem_subject":"East Java Basin","subitem_subject_scheme":"Other"},{"subitem_subject":"Unconformity","subitem_subject_scheme":"Other"},{"subitem_subject":"Basin Evolution","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Upper Cenozoic Calcareous Nannofossil Biostratigraphy and Basin Evolution of the East Java Basin Indonesia","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Upper Cenozoic Calcareous Nannofossil Biostratigraphy and Basin Evolution of the East Java Basin Indonesia"}]},"item_type_id":"10006","owner":"3","path":["1485"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-12-06"},"publish_date":"2022-12-06","publish_status":"0","recid":"5803","relation_version_is_last":true,"title":["Upper Cenozoic Calcareous Nannofossil Biostratigraphy and Basin Evolution of the East Java Basin Indonesia"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T10:41:43.216994+00:00"}
