Professor Tatsuki Tsujimori of the Tohoku University Northeast Asian Studies Center (also serving as the Graduate School of Science, Department of Earth Sciences) edited a collection of academic papers on "Hisui," the national stone of Japan, and edited the English journal of the Japan Society for Mineral Sciences. Will be published in.
In 2016, the Japanese Society of Mineral Sciences selected "Jade" as the national stone of Japan.In response to this, the Japan Society for Mineral Sciences planned a special issue on jadeite, with Professor Kiyoshi Tsujimori of the Tohoku University Northeast Asian Research Center, former Deputy Director Hiroshi Miyajima of the Fossa Magna Museum in Itougawa City, and Ritsuro Miyawaki, Director of the Earth Science Research Department of the National Museum of Nature and Science. As a guest editor, he added a preface to 10 articles on jade and published it as a special issue'Jadeite and Jadeitite'in the English magazine Vol. 112, No. 5 of the Japan Society for Mineral Sciences.
About 80 years ago, Dr. Yoshinori Kono, an assistant at Tohoku Imperial University (at that time), identified the jade from Itoigawa, Niigata Prefecture, and in 1939, it was published in the Japanese journal of the Japan Rock and Mineral Deposit Society, one of the predecessors of the Japan Mineral Science Society. Reported a paper by chemical analysis.Since it became clear that jadeite is produced in Itoigawa, multiple jadeite producing areas have been discovered in Japan, and rocks (metamorphic rocks) containing a type of stable pyroxene called "jadeite" that composes jadeite. Multiple production areas have also been confirmed.It can be said that these rocks are very valuable for understanding the geological phenomenon of the boundary where the plate narrows.
The papers included in this collection of papers are based on the research results of Japanese jade by Japanese researchers, and summarize the characteristics of Japanese jade, comparison with world jade, and the history of Japanese jade research. There is a wide range of content, including a general remark on the extraterrestrial jade stone partially formed in the meteorite due to a large impact such as a celestial collision, and this is the academic value of jade, which was selected as the national stone of Japan, from Japan to overseas. It plays a role of transmitting to.
