Similar variation is found in the lower member of Waianae volcano, Oahu Island. Marked increase in K2O/Na2O ratio of the historic lavas of Kilauea as compared with that of early historic and many prehistoric lavas of the same volcano may correspond to a part of such periodic variations in K2O/Na2O ratio as represented by the above two examples. As one possible mechanism for such increase in K2O/Na2O ratio, fractional crystallization of K2O-poor plagioclase is proposed.|\u30ad\u30e9\u30a6\u30a8\u30a2\u706b\u5c71\u30de\u30ab\u30aa\u30d7\u30d2\u706b\u53e3\u58c1\u306b\u9732\u51fa\u3059\u308b,\u4e00\u9023\u306e\u5148\u53f2\u6642\u4ee3\u306e\u30bd\u30ec\u30a2\u30a4\u30c8\u8cea\u6eb6\u5ca9\u3092\u63a1\u96c6\u3057,30\u500b\u306e\u6a19\u672c\u306b\u3064\u3044\u3066Na2O\u3068K2O,\u305d\u306e\u3046\u30613\u500b\u306b\u3064\u3044\u3066\u306f\u66f4\u306bSiO2,\u4ed6\u306e3\u500b\u306b\u3064\u3044\u3066\u306f13\u6210\u5206\u306e\u5b9a\u4f4d\u3092\u884c\u3064\u305f.\u305d\u306e\u7d50\u679c,K2O/Na2O\u6bd4\u304c\u6642\u9593\u3068\u5171\u306b\u9855\u8457\u306a\u5468\u671f\u7684\u5909\u5316\u3092\u793a\u3059\u3053\u3068\u304c\u660e\u3089\u304b\u306b\u306a\u3064\u305f.Na2O+K2O\u3082\u307b\u307c\u540c\u69d8\u306e\u5909\u5316\u3092\u793a\u3059.\u540c\u3058\u3088\u3046\u306a\u5909\u5316\u306f\u30aa\u30a2\u30d5\u5cf6\u30ef\u30a4\u30a2\u30ca\u30a4\u706b\u5c71\u306b\u304a\u3044\u3066\u3082\u898b\u3089\u308c\u308b.\u30ad\u30e9\u30a6\u30a8\u30a2\u706b\u5c71\u306e\u6700\u8fd1\u306e\u6eb6\u5ca9\u306eK2O/Na2O\u6bd4\u306f,\u540c\u706b\u5c71\u306e20\u4e16\u7d00\u4ee5\u524d\u306e\u6eb6\u5ca9\u306e\u305d\u308c\u306b\u6bd4\u3079\u8457\u3057\u304f\u9ad8\u3044\u304c,\u3053\u308c\u306f,\u4e0a\u306b\u8ff0\u3079\u305f\u5468\u671f\u7684\u5909\u5316\u306e2\u4f8b\u3068\u540c\u3058\u73fe\u8c61\u304b\u3082\u77e5\u308c\u306a\u3044.\u3053\u308c\u3092\u8aac\u660e\u3059\u308b1\u3064\u306e\u53ef\u80fd\u6027\u3068\u3057\u3066,K2O\u306b\u4e4f\u3057\u3044\u659c\u9577\u77f3\u304c\u30de\u30b0\u30de\u304b\u3089\u6676\u51fa\u5206\u96e2\u3059\u308b\u30e2\u30c7\u30eb\u3092\u63d0\u5531\u3057\u305f.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "130345", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u8352\u7267, \u91cd\u96c4"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/0000033382", "subitem_identifier_reg_type": "JaLC"}]}, "item_4_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240"}]}, "item_4_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00162258", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00408972", "subitem_source_identifier_type": "ISSN"}]}, "item_4_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "453", "subitem_subject_scheme": "NDC"}]}, "item_4_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute, University of Tokyo"}]}, "item_4_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute"}, {"subitem_text_value": "U.
