This paper describes the geochemistry of the Permian\u2013Triassic volcanoplutonic rocks at the Oyut-uul area, northeast of Darkhan City, Mongolia. The mid-ocean ridge basalt (MORB)-normalized multi-element pattern (spidergram) for the examined rocks shows an enrichment of large-ion lithophile elements (LILE) against high-field-strength elements (HFSE) and rare earth elements (REE), with clear negative Nb anomaly to suggest an arc-related igneous activity. The most data are plotted in the calc-alkaline field in the SiO2 vs. FeO*/MgO diagram. It is, thus, concluded that the examined rocks are of calc-alkaline series formed at an arc environment. The present samples, 53\u2013 78 wt.% SiO2, high Al2O3 and Sr concentrations, high La/Yb ratio, and low K2O/Na2O ratio, have adakitic nature derived from oceanic slab-melt. They are quite similar to the marginal facies of the Kitakami adakitic granite of Japan in Sr/Y-Y relationship, MgO concentration, spidergram, and REE chondrite-normalized pattern. It is considered that the marginal facies of the Kitakami adakitic granite was resulted from interaction between the slab-melt and mantle peridotite/lower crustal amphibolite during their ascent. The Oyut-uul rocks might be also derived from oceanic slab-melt interacted with mantle peridotite/lower crustal amphibolite.", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/bulnum.033.02", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u540d\u53e4\u5c4b\u5927\u5b66\u535a\u7269\u9928"}]}, "item_9_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN\uff08print\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "1346-8286", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "TSUKADA, Kazuhiro"}], "nameIdentifiers": [{"nameIdentifier": "75279", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "PUREVSUREN, Nemekhbayar"}], "nameIdentifiers": [{"nameIdentifier": "75280", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "NURAMKHAAN, Manchuk"}], "nameIdentifiers": [{"nameIdentifier": "75281", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "GANTUMUR, Onon"}], "nameIdentifiers": [{"nameIdentifier": "75282", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "HASEGAWA, Hitoshi"}], "nameIdentifiers": [{"nameIdentifier": "75283", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "YAMAMOTO, Koshi"}], "nameIdentifiers": [{"nameIdentifier": "75284", "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": "2018-03-15"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "033_02.pdf", "filesize": [{"value": "1.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1000000.0, "url": {"label": "033_02", "url": "https://nagoya.repo.nii.ac.jp/record/25216/files/033_02.pdf"}, "version_id": "36665fab-5b70-4534-8bb2-58161801bb8a"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Late Paleozoic\u2013Early Mesozoic", "subitem_subject_scheme": "Other"}, {"subitem_subject": "adakites", "subitem_subject_scheme": "Other"}, {"subitem_subject": "southern margin of Siberian continent", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mongolia", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "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": "Geochemistry of the Permian\u2013Triassic volcano-plutonic rocks in the Oyut-uul area, northeast of Darkhan, Mongolia : Magmatism at southern margin of Siberian continent", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Geochemistry of the Permian\u2013Triassic volcano-plutonic rocks in the Oyut-uul area, northeast of Darkhan, Mongolia : Magmatism at southern margin of Siberian continent"}]}, "item_type_id": "9", "owner": "1", "path": ["367/368/369/2061"], "permalink_uri": "https://doi.org/10.18999/bulnum.033.02", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2015-05-15"}, "publish_date": "2015-05-15", "publish_status": "0", "recid": "25216", "relation": {}, "relation_version_is_last": true, "title": ["Geochemistry of the Permian\u2013Triassic volcano-plutonic rocks in the Oyut-uul area, northeast of Darkhan, Mongolia : Magmatism at southern margin of Siberian continent"], "weko_shared_id": 3}
