The formation consists of mudstone, shale and occasional beds of conglomerate, limestone and coal. It exhibits poor bedding and shows rapid lithologic changes vertically and horizontally. The formation is subdivided into several members which are all essentially coal measures and limestones. Mineralogical study of the Malubog Formation focused on the gently dipping strata of the argillaceous-arenaceous sedimentary rocks with generally minimal coal seam interbeds. Analytical testworks, involving x-ray diffraction (XRD), differential thermal analysis-thermogravimetry (DTA-TG), scanning electron microscopy (SEM) and energy dispersive x-ray (EDX), performed on the \u003c2 μm size fraction indicate that multi-phase phyllosilicates of smectite, kaolinite, illite, mica, chlorite and mixed-layer varieties constitute essentially the argillaceous- arenaceous sedimentary rocks. These clays blend into several mineral assemblages that are almost all smectite-dominated. Most combinations include three or four clay species with varying peculiarities. Accessory non-phyllosilicates minerals are finely crystalline silica polymorphs (quartz, cristobalite, tridymite), feldspar, calcite, zeolite and jarosite (some alunite). Although the mineralogical components in many assemblages may appear the same, they reflect quite differences in characteristics and diversity of the sedimentary horizons. Most of these clays and mineral assemblages seem to convey diagenetic style of sedimentary petrogenesis, few relate to pedogenesis, and some exhibit efffects of hydrothermal alteration. The regime of diagenetic alterations infers to have progressed in alkaline marine environment, stimulated by low to moderate thermodynamic conditions at shallow to moderate burial depth. In the pedogenetic environment, chemical weathering suggests moderate conversion condition without reaching monosiallitization. Clays and mineral assemblages in hydrothermally altered ground reveal acid-sulfate to intermediate types.", "subitem_description_type": "Other"}]}, "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": "13456938", "subitem_source_identifier_type": "ISSN"}]}, "item_7_source_id_9": {"attribute_name": "NII書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11246904", "subitem_source_identifier_type": "NCID"}]}, "item_7_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "400", "subitem_subject_scheme": "NDC"}]}, "item_7_subject_20": {"attribute_name": "NIIsubject", "attribute_value_mlt": [{"subitem_subject": "自然科学", "subitem_subject_scheme": "Other"}]}, "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_text_30": {"attribute_name": "NIIタイプ", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "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": "ALETA, Dennis Gerald A."}], "nameIdentifiers": [{"nameIdentifier": "72355", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TOMITA, Katsutoshi"}], "nameIdentifiers": [{"nameIdentifier": "72356", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KAWANO, Motoharu"}], "nameIdentifiers": [{"nameIdentifier": "72357", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "ALETA, Josephine T."}], "nameIdentifiers": [{"nameIdentifier": "72358", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "LUPO, Elena S."}], "nameIdentifiers": [{"nameIdentifier": "72359", "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": "2016-10-27"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00002363332.pdf", "filesize": [{"value": "2.1 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2100000.0, "url": {"label": "KJ00002363332.pdf", "url": "https://ir.kagoshima-u.ac.jp/record/3322/files/KJ00002363332.pdf"}, "version_id": "9ea9347a-14f1-41e8-9a43-b5d26b1ee3b9"}]}, "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": "Clay Mineralogical Study of the Tertiary Malubog Formation, Cebu Province, Philippines", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Clay Mineralogical Study of the Tertiary Malubog Formation, Cebu Province, Philippines"}]}, "item_type_id": "7", "owner": "3", "path": ["53", "5057"], "permalink_uri": "http://hdl.handle.net/10232/805", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-03-07"}, "publish_date": "2007-03-07", "publish_status": "0", "recid": "3322", "relation": {}, "relation_version_is_last": true, "title": ["Clay Mineralogical Study of the Tertiary Malubog Formation, Cebu Province, Philippines"], "weko_shared_id": 3}
