Twenty hydrate-bearing sediment cores were retrieved, and methanestable isotopes of hydrate-bound gases (δ13C and δ2\nH of − 47.8‰ to− 44.0‰ V-PDB and− 280.5‰ \nto− 272.8‰ V-SMOW, respectively) indicated their thermogenic origin accompanied with secondary \nmicrobial methane. Powder X-ray difraction patterns of the crystals and molecular composition of \nthe hydrate-bound gases suggested that structure II crystals showed a high concentration of ethane \n(around 14% of hydrate-bound hydrocarbons), whereas structure I crystals showed a relatively low \nconcentration of ethane (2–5% of hydrate-bound hydrocarbons). These diferent crystallographic \nstructures comprised complicated layers in the sub-lacustrine sediment, suggesting that the gas \nhydrates partly dissociate, concentrate ethane and form structure II crystals. We concluded that a high \nconcentration of thermogenic ethane primarily controls the crystallographic structure of gas hydrates \nand that propane, iso-butane (2-methylpropane) and neopentane (2,2-dimethylpropane) are encaged \ninto crystals in the re-crystallisation process","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"nature springer","subitem_publisher_language":"en"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1038/s41598-020-71410-2","subitem_relation_type_select":"DOI"}}]},"item_3_select_195":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher","subitem_select_language":"en"}]},"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":"Akihiro Hachikubo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hirotsugu Minami","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Satoshi　Yamashita","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Andrey Khabuev","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Alexey Krylov","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Gennadiy Kalmychkov","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Jefrey Poort","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Marc De Batist","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Alexandr Chenskiy","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Andrey Manakov","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Oleg Khlystov","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-04-18"}],"filename":"s41598-020-71410-2(1).pdf","filesize":[{"value":"8.2 MB"}],"format":"application/pdf","url":{"url":"https://kitami-it.repo.nii.ac.jp/record/2000417/files/s41598-020-71410-2(1).pdf"},"version_id":"de23eeb2-22c7-453e-94b7-05f3c41b8076"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Characteristics of hydrate-bound gas retrieved at the Kedr mud volcano (southern Lake Baikal)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Characteristics of hydrate-bound gas retrieved at the Kedr mud volcano (southern Lake Baikal)","subitem_title_language":"en"}]},"item_type_id":"3","owner":"15","path":["87"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-04-18"},"publish_date":"2023-04-18","publish_status":"0","recid":"2000417","relation_version_is_last":true,"title":["Characteristics of hydrate-bound gas retrieved at the Kedr mud volcano (southern Lake Baikal)"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-04-18T05:44:15.463816+00:00"}
