Monazites in foliated biotite leucogranite exhibit significant chemical characteristics by different grains or within individual grains. Some monazite grains have strongly undergone the chemical alteration through the monazite-huttonite substitution (p^5+ +REE^3+ \u2194Si^4+ + Th^4+). Other grains, especially surrounding feldspars, have slightly occurred the monazite-cheralite substitution (2REE3+ \u2194 Ca^2+ +Th^4+), and have the relatively higher concentrations of ThO2, compared to the huttonite-rich monazite. Furthermore, a significant intra-crystal chemical zoning is observed in individual monazite grains, indicating that Y content decreases from core and to rim. Monazites selected using chemical criteria (0.95 \u003c (Ca + Si)/ (Th + U +Pb +S) \u003c 1.05), which could be discriminate the metamict monazite due to the destruction of the crystalline structure from the original monazites, construct together a pseudo-isochron of 16.4 \u00b1 1.7 Ma in PbO-ThO2* diagram. Also, monazites from quartz-rich leucogranite have homogenous compositions of Y, Th and U contents, and yields the weight mean chemical ages of 16.6 \u00b1 2.6 Ma, in agreement with the age of the foliated biotite leucogranite. Our data suggest that the CHIME ages combined with the chemical zoning patterns such as Y, Th, U, Ca, and Pb of monazites can provide a powerful tool to elucidate the complex zoning patterns of monazite and to know the precise timing of granite crystallization from magmatic monazite.", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "\u5185\u5bb9\u8a18\u8ff0", "attribute_value_mlt": [{"subitem_description": "\u7b2c23\u56de\u540d\u53e4\u5c4b\u5927\u5b66\u5e74\u4ee3\u6e2c\u5b9a\u7dcf\u5408\u7814\u7a76\u30bb\u30f3\u30bf\u30fc\u30b7\u30f3\u30dd\u30b8\u30a6\u30e0\u5e73\u621022(2010)\u5e74\u5ea6\u5831\u544a", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.22.55", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u540d\u53e4\u5c4b\u5927\u5b66\u5e74\u4ee3\u6e2c\u5b9a\u8cc7\u6599\u7814\u7a76\u30bb\u30f3\u30bf\u30fc"}]}, "item_9_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u4eca\u5c71, \u6b66\u5fd7"}], "nameIdentifiers": [{"nameIdentifier": "83196", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u9234\u6728, \u548c\u535a"}], "nameIdentifiers": [{"nameIdentifier": "83197", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Imayama, Takeshi"}], "nameIdentifiers": [{"nameIdentifier": "83198", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Suzuki, Kazuhiro"}], "nameIdentifiers": [{"nameIdentifier": "83199", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "imayama2010.pdf", "filesize": [{"value": "1.8 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1800000.0, "url": {"label": "imayama2010.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/14598/files/imayama2010.pdf"}, "version_id": "bc75658a-c35b-4712-b400-78c6478692f4"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Chemical age", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Monazite", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Himalaya leucogranite", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u6975\u6771\u30cd\u30d1\u30fc\u30eb\u30d2\u30de\u30e9\u30e4\u512a\u767d\u8cea\u82b1\u5d17\u5ca9\u306e\u9ad8\u7cbe\u5ea6CHIME\u30e2\u30ca\u30b6\u30a4\u30c8\u5e74\u4ee3(\u4e88\u5831)", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u6975\u6771\u30cd\u30d1\u30fc\u30eb\u30d2\u30de\u30e9\u30e4\u512a\u767d\u8cea\u82b1\u5d17\u5ca9\u306e\u9ad8\u7cbe\u5ea6CHIME\u30e2\u30ca\u30b6\u30a4\u30c8\u5e74\u4ee3(\u4e88\u5831)"}]}, "item_type_id": "9", "owner": "1", "path": ["879/1183/1184/1395"], "permalink_uri": "https://doi.org/10.18999/sumrua.22.55", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2012-06-05"}, "publish_date": "2012-06-05", "publish_status": "0", "recid": "14598", "relation": {}, "relation_version_is_last": true, "title": ["\u6975\u6771\u30cd\u30d1\u30fc\u30eb\u30d2\u30de\u30e9\u30e4\u512a\u767d\u8cea\u82b1\u5d17\u5ca9\u306e\u9ad8\u7cbe\u5ea6CHIME\u30e2\u30ca\u30b6\u30a4\u30c8\u5e74\u4ee3(\u4e88\u5831)"], "weko_shared_id": null}
