This rock is exposed to chemical weathering in tropical conditions and through the leaching reactions leave a friable mantle of in situ regolithic materials. It is envisaged that the serpentine was derived from a pyroxene-rich peridotite. The \u003c2μm clay fraction of four regolithic materials obtained from this rockmass in Camp 7,Minglanilla were examined by means of x-ray diffractometry (XRD), differential thermal analysis (DTA), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and energy dispersive x-ray (EDX). Results of analyses showcase the polymineralic and heterogeneous nature of the weathered specimens with serpentine predominating, and could be differentiated possibly into two distinct assemblages. The first assemblage consists principally of serpentine-talc-chlorite-smectite and the second assemblage consists of serpentine-chlorite-smectite. Kaolinite is present in trace amounts in both suites. It is strongly perceived that these secondary minerals are genetic products from cadence of chemical alterations of primary ferromagnesian minerals particularly orthopyroxenes and clinopyroxenes. The two assemblages appear to interpret the weathering reaction stages that the hypermelanic peridotite protolith had undergone. The first assemblage possibly corresponds to saprock (friable rock zone) which suggests the earlier stage and lesser intensity of weathering while the second assemblage possibly relates to saprolite (argillized solifluxed zone) which indicates the more advanced and greater intensity of weathering. The transition from the first assemblage to the second assemblage appears telescoping as indicated by the gradating loss of talc in the system. Both assemblages appear highly magnesian, ferruginous, siliceous and non-aluminous.", "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": "74099", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TOMITA, Katsutoshi"}], "nameIdentifiers": [{"nameIdentifier": "74100", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "ALETA, Josephine T."}], "nameIdentifiers": [{"nameIdentifier": "74101", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "LUCERO, Abraham R."}], "nameIdentifiers": [{"nameIdentifier": "74102", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KAWANO, Motoharu"}], "nameIdentifiers": [{"nameIdentifier": "74103", "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": "2016-10-31"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00000042914.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "KJ00000042914.pdf", "url": "https://ir.kagoshima-u.ac.jp/record/12218/files/KJ00000042914.pdf"}, "version_id": "ee454cc1-f983-46c4-9306-2532e2c288aa"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Serpentine", "subitem_subject_scheme": "Other"}, {"subitem_subject": "chlorite", "subitem_subject_scheme": "Other"}, {"subitem_subject": "talc", "subitem_subject_scheme": "Other"}, {"subitem_subject": "smectite", "subitem_subject_scheme": "Other"}, {"subitem_subject": "saprock", "subitem_subject_scheme": "Other"}, {"subitem_subject": "saprolite", "subitem_subject_scheme": "Other"}, {"subitem_subject": "peridotite", "subitem_subject_scheme": "Other"}]}, "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 Mineralogy of the Weathered Materials from the Serpentinized Peridotite in Minglanilla, Cebu Province, Philippines", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Clay Mineralogy of the Weathered Materials from the Serpentinized Peridotite in Minglanilla, Cebu Province, Philippines"}]}, "item_type_id": "7", "owner": "3", "path": ["53", "5056"], "permalink_uri": "http://hdl.handle.net/10232/797", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-08-01"}, "publish_date": "2008-08-01", "publish_status": "0", "recid": "12218", "relation": {}, "relation_version_is_last": true, "title": ["Clay Mineralogy of the Weathered Materials from the Serpentinized Peridotite in Minglanilla, Cebu Province, Philippines"], "weko_shared_id": 3}
