The pre-Komitake Volcano is characterized by hornblende-bearing andesite and dacite, in contrast to the porphyritic basaltic rocks of Komitake Volcano and to the olivine-bearing basaltic rocks of Fuji Volcano. K-Ar age determinations and geological analysis of drilling cores suggest that the pre-Komitake Volcano began with effusion of basaltic lava flows around 260 ka and ended with explosive eruptions of basaltic andesite and dacite magma around 160 ka. After deposition of a thin soil layer on the pre-Komitake volcanic rocks, successive effusions of lava flows occurred at Komitake Volcano until 100 ka. Explosive eruptions of Fuji Volcano followed shortly after the activity of Komitake. The long-term eruption rate of about 3 km3/ka or more for Fuji Volcano is much higher than that estimated for pre-Komitake and Komitake. The chemical variation within Fuji Volcano, represented by an increase in incompatible elements at nearly constant SiO2, differs from that within pre-Komitake and other volcanoes in the northern Izu-Bonin arc, where incompatible elements increase with increasing SiO2. These changes in the volcanism in Mount Fuji may have occurred due to a change in regional tectonics around 150 ka, although this remains unproven. c 2010 Blackwell Publishing Asia Pty Ltd.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1111/j.1440-1738.2010.00722.x"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1440-1738", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Mitsuhiro Yoshimoto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Toshitsugu Fujii", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takayuki Kaneko", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Atsushi Yasuda", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Setsuya Nakada", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Akikazu Matsumoto", "creatorNameLang": "en"}]}]}, "item_title": "Evolution of Mount Fuji, Japan: Inference from drilling into the subaerial oldest volcano, pre-Komitake", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Evolution of Mount Fuji, Japan: Inference from drilling into the subaerial oldest volcano, pre-Komitake", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4778", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4778", "relation": {}, "relation_version_is_last": true, "title": ["Evolution of Mount Fuji, Japan: Inference from drilling into the subaerial oldest volcano, pre-Komitake"], "weko_shared_id": -1}
