In an early stage of pearl formation, it is often that thick conchiolin and prismatic layers deposite on the surface of a nucleus. The conchiolin was found to have membranous or fibrous structure (Fig. 5). The prismatic layer seems to grow in such a way that at first many granular prisms scatter on the surface of conchiolin or nucleus, and there they grow to change their forms from oolitic to mammillary, and then to rosette-shaped, and to honeycomb prisms. The mossy structure of a prismatic layer seems to be due to another process of growth them mentioned above. Each prism grew in two directions, perpendicular and horizontal to its surface. On the surface of the prism, calcite crystals were observed to have developed in step-, redge-like or homogenous structure (Figs. 5, 6 and 7), and concentric and radial patterns were observed at the central part of the prisms.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立真珠研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"National Pearl Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"pearl_k_251","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本真珠振興会Archive"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://jp-pearl.com/wp-content/uploads/2018/04/houkoku004.pdf#001","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00091717","subitem_source_identifier_type":"NCID"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Wada, Koji","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"和田, 浩爾","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"ワダ, コウジ","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Wada","familyNameLang":"en"},{"familyName":"和田","familyNameLang":"ja"},{"familyName":"ワダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Koji","givenNameLang":"en"},{"givenName":"浩爾","givenNameLang":"ja"},{"givenName":"コウジ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3282","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"真珠形成初期の顕微鏡的観察２","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"真珠形成初期の顕微鏡的観察２","subitem_title_language":"ja"},{"subitem_title":"Microscopic observations of cultured pearls at their early formation II.","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-27"},"publish_date":"2024-06-27","publish_status":"0","recid":"2008943","relation_version_is_last":true,"title":["真珠形成初期の顕微鏡的観察２"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-13T02:39:54.554196+00:00"}
