Normal alkanes ranging in carbon chain length from nC_<12> to nC_<30>, pristane and/or phytane were found in all the samples studied with concentrations ranging from 0.24 to 25μg/g of dry sample, along with near unity of carbon preference index (0.91-1.4). The major constituents were all short-chain n-alkanes (<C_<20>, nC_<16>, nC_<17>, nC_<18>, nC_<19>), pristane and/or phytane. Normal alkanoic acids of carbon chain lengths between nC_6 and nC_<28> were found in a sedimentary rock from the Carapace Nunatak and in silicified wood from the Allan Hills with low concentrations (2.3-25μg/g), together with the dominance of even-carbon numbers (carbon preference index, 1.6-2.8). The higher abundances of long-chain (&ge;nC_<20>) n-alkanes and n-alkanoic acids in the sedimentary rock from the Carapace Nunatak imply that the contribution of land plants to the sedimentary paleoenvironment of this area was greater than that in the Allan Hills. The pristane/phytane ratios suggest that the sedimentary paleoenvironment of the Allan Hills was oxic compared with that of the Carapace Nunatak.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Chemistry, the College of Arts and Sciences, the University of Tokyo/National Institute of Polar Research/Japan National Oil Corporation/Department of Chemistry, the College of Arts and Sciences, the University of Tokyo"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1986-09-01"}],"displaytype":"detail","filename":"KJ00000012572.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012572","url":"https://nipr.repo.nii.ac.jp/record/2019/files/KJ00000012572.pdf"},"version_id":"6cb007f8-8d91-40b6-b92e-d78e7f3d2e1e"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Alkanes and alkanoic acids in the Beacon Supergroup samples from the Allan Hills and the Carapace Nunatak in Antarctica","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Alkanes and alkanoic acids in the Beacon Supergroup samples from the Allan Hills and the Carapace Nunatak in Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["397"],"pubdate":{"attribute_name":"公開日","attribute_value":"1986-09-01"},"publish_date":"1986-09-01","publish_status":"0","recid":"2019","relation_version_is_last":true,"title":["Alkanes and alkanoic acids in the Beacon Supergroup samples from the Allan Hills and the Carapace Nunatak in Antarctica"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:55:39.645832+00:00"}
