Professor Takashi Miyano passed away at Tsukuba University Hospital in Ibaraki on October 21st, 2002 at the age of 55. With his sudden death, the Institute of Geoscience lost a respected scientist and teacher of petrology and Precambrian geology.
Professor Miyano was born in Kumamoto on November 6th, 1946 and grew up in Kagoshima. After graduating from Kagoshima Gyokuryu High School, he entered Faculty of Science, Tokyo University of Education in 1966. He graduated from the University in 1970 with his major in geology. He continued his post-graduate studies at the same Institution under the supervision of Professor Toshiya Miyazawa. From 1970 to 1971, he spent one year at Western Australia for fieldwork on Proterozoic banded iron-formation in Hamersley area as a part of his post-graduate project. He received his D. Sc. degrees in 1976 for his dissertation entitled "Physicochemical environments during burial metamorphism of the Proterozoic iron formation in the Hamersley area, Western Australia". Immediately after obtaining the degree, he published a series of papers on Mining Geology in 1976 and Journal of the Geological Society of Japan in 1978 as a result of his D. Sc. works. His paper entitled " Physicochemical environments during burial metamorphism of the Dales Gorge Member, Hamersley Group, Western Australia" published in 1976 on Mining Geology won a prize of the best paper of the year in the Society of Mining Geologists of Japan. He was indeed a pioneer of the Precambrian geology in Japan, and since then, a field of his research has been enlarged to metamorphic petrology.
His professional carrier started from 1976 as a research fellow of Japan Society for the Promotion of Science (JSPS). He was then appointed to Technical Official at the University of Tsukuba in 1978. He was promoted to Lecturer in the Institute of Geoscience at the University of Tsukuba in July 1979, to Associate Professor in April 1988, and to Professor in May 1997.
In 1981, he accepted a post-doctoral appointment in the Department of Geology at Indiana University. In a really solid year at Indiana, he collaborated with Professor C. Klein and published many scientific papers with him. One of the main features of this work involved determination of stability fields of metamorphic minerals in low- to medium-grade banded iron-formations using thermodynamic techniques. Upon completing his post-doctoral research at Indiana, he spent about fifteen months, from 1983 to 1984, in the Republic of South Africa where he worked with Professors N. J. Beukes and D. D. van Reenen at Rand Afrikaans University (RAU). During his stay in South Africa, he visited many geologically interesting places such as the Limpopo Belt (the oldest granulite terrane), the Bushveld Complex (the largest igneous complex), Archean greenstone belts, and so on for his future research. He maintained his ties with the geology group at RAU and eventually established a joint program that resulted in collaborative research among the staff and graduate students of RAU and Institute of Geoscience. The relationship between the above two institutes still continues, and all his students who received M. Sc. or D. Sc. degrees under his guidance have visited southern Africa for fieldwork and collaborative work with RAU geologists.
Although his health has been weakened since 1991, he admirably managed to carry out his heavy duties on research, education, and administration in the University. In spite of such situation, he visited Chiba University in 2001 to give a lecture on metamorphic petrology. Even a week before his passing, he attended a seminar on petrology and discussed their thesis with his students. We have greatly appreciated not only his contribution to metamorphic petrology in Australia, southern Africa, and Japan but also his open-minded personality and attitude on education. We will always remember him with deep affection.
Professor Miyano is survived by his wife, Mrs. Sumiko Miyano, and two daughters, Megumi and Mutsumi.
