The pyroxene-andesite lava series contain anorthite megacrysts with the composition Ab4An94Ot2 (Ab: albite; An: anorthite; Ot: other minor end-members). Ideal anorthite is CaAl2Si2O8; however, the present colourless and yellow anorthite megacrysts can also host minor amounts of Mn, Zn, and –(CH2)n-. Yellow anorthite is a new variant for feldspar groups. Moreover, the crystal structure establishes excess Si and Al cations as □Si4O8 and AlAl3SiO8 endmembers, respectively.\n　Chromium-fused salites (clinopyroxenes) rich in Al2O3 are observed as inclusions tens of micrometers in size encompassed by yellow anorthite megacrysts. This additional solubility of Al2O3 points to crystallization of the present clinopyroxene under high-pressure conditions. The natural formation and observation of the present anorthites clarifies that metallogenesis related to hydrocarbons maybe contributed to the far-reaching effects of the mixing of basaltic magma with seawater and slab sediments on the crystallization of these megacrysts from the melt under high-pressure conditions.", "subitem_description_type": "Other"}]}, "item_7_full_name_2": {"attribute_name": "著者よみ", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "142487", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "マツイ, トモアキ"}]}]}, "item_7_full_name_3": {"attribute_name": "別言語の著者", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "142488", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "MATSUI, Tomoaki"}]}]}, "item_7_publisher_23": {"attribute_name": "公開者・出版者", "attribute_value_mlt": [{"subitem_publisher": "鹿児島大学"}]}, "item_7_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "24359807", "subitem_source_identifier_type": "ISSN"}]}, "item_7_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "450", "subitem_subject_scheme": "NDC"}]}, "item_7_text_24": {"attribute_name": "公開者よみ", "attribute_value_mlt": [{"subitem_text_value": "カゴシマ ダイガク"}]}, "item_7_text_25": {"attribute_name": "公開者別名", "attribute_value_mlt": [{"subitem_text_value": "Kagoshima University"}]}, "item_7_version_type_14": {"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_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "松井, 智彰"}], "nameIdentifiers": [{"nameIdentifier": "142486", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2023-04-07"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "24359807_v74_p31-44.pdf", "filesize": [{"value": "2.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2400000.0, "url": {"label": "24359807_v74_p31-44", "url": "https://ir.kagoshima-u.ac.jp/record/16601/files/24359807_v74_p31-44.pdf"}, "version_id": "8206c94a-37d4-410c-a6ee-c674d0753d3b"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "anorthite", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "megacryst", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hakone Volcano", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "yellow colour", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "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": "箱根火山産灰長石巨晶の結晶化学的研究", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "箱根火山産灰長石巨晶の結晶化学的研究"}, {"subitem_title": "Crystal Chemistry of Anorthite Megacrysts in Volcanic Rocks from Hakone Volcano, Japan", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "29", "path": ["42", "6120"], "permalink_uri": "http://hdl.handle.net/10232/00032485", "pubdate": {"attribute_name": "公開日", "attribute_value": "2023-04-07"}, "publish_date": "2023-04-07", "publish_status": "0", "recid": "16601", "relation": {}, "relation_version_is_last": true, "title": ["箱根火山産灰長石巨晶の結晶化学的研究"], "weko_shared_id": -1}
