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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"4778","relation_version_is_last":true,"title":["Evolution of Mount Fuji, Japan: Inference from drilling into the subaerial oldest volcano, pre-Komitake"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T06:09:47.851908+00:00"}
