Sakai’s report was new information on the geology of the Mino Terrane, and gave us motivation for re-study of the area from the micropaleontological standpoint. At Hid-Kanayama, we started to detailed mapping and sampling of the Radiolaria-bearing rocks; and I asked Dr. Ken Shibata (Geologicl Survey of Japan) to carry out the isotope agedetermination for the rocks in the Hida-Kanayama area. We reported our study results in the meeting of the Paleontological Society of Japan held at Nagoya University on Oct. 20, 1979 (Mizutani, Okamura and Shibata, 1979). We also started to re-study throughout the Mino Terrane from a new viewpoint. Surprisingly enough, staffs and graduate students found siliceous shale in many areas in the region which contains the Jurassic radiolarians ranging in age from Bathonian to Tithonian. I reported orally the result of our studies to Dr. Teiichi Kobayashi, Emeritus Professor of Tokyo University, and he strongly recommended me to publish it on the Proceeding of Japan Academy (Mizutani et al., 1981). I also described my own study result and publisehed it on the Bulletin of the Mizunami Fossil Museum (Mizutani, 1981). Petrographic researches of these sedimentary rocks were carried out, particularly concerning the origin of chert or siliceous materials. It seemed to me that the fundamental problem lies in the origin of silica and the process of crystallization from amorphous silica to quartz in chert or siliceous shale. I did an experimental research on transformation of amorphous silica to quartz under the hydrothermal conditions. I found that the transformation process from amorphous silica to cristobalite and then to quartz could be reasonably expressed by differential equations, when we introduced the induction period for the reactions. I have not yet done, however, any discussions on the essensial meaning of this induction period. In the present paper, I will examine many kinetic reactions in which the reactions are related with the induction period. It seems to me that amorphous silica, i.e. nano-sized particle necessitates the induction period when it is transformed to another phase. After my own work on the Mazegawa Formation in 1981, Wakita (1987) studied the same area in detail, and found that the younger radiolarian assemblage from Tithonian to Berriasian, composed of Pseudodictyomitra carpatica (Lozyniak) and Ditrabs sansalvadorensis (Pessagno) of the “Pc assemblage” in the Mino Terrane. He extended his field work to the entire part of the Mino Terrane (Wakita, 1988a, 1988b). He thought that his idea would be applied in other places, and carried out a research work on the tectonic evolution of South and Southeast Asia. His idea was persuasively applied to that region like the Mino Terrane in Japan (Wakita et al., 1997; Wakita and Metcalfe, 2005). The latest volume of Tectonophysics (vol.568-569) was planned to publish a special issue on mélange with various examples from active tectonic belts in the world. Wakita (2012) also presented his paper and discussed the mélange formation in the Mino and the Chichibu Terranes from SW Japan. This Tectonophysics was published in color; all the maps and figures in each paper on the complex and complicated mélange provide useful information for us.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/18191"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/bulnum.028.06","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学博物館","subitem_publisher_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_source_id_7":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"1346-8286","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"水谷, 伸治郎","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"48698","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MIZUTANI, Shinjiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"48699","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":"2018-02-20"}],"displaytype":"detail","filename":"No28-6.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"No28-6.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/16158/files/No28-6.pdf"},"version_id":"3ae1f81e-d794-4a03-95f0-a9ea1280f2e6"}]},"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":"馬瀬川層の珪質頁岩と放散虫化石","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"馬瀬川層の珪質頁岩と放散虫化石","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["1499"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-06-11"},"publish_date":"2013-06-11","publish_status":"0","recid":"16158","relation_version_is_last":true,"title":["馬瀬川層の珪質頁岩と放散虫化石"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T05:18:36.080889+00:00"}
