Ted Ringwood

Alfred Edward Ringwood FRS ( born April 19, 1930 in Kew, a suburb of Melbourne, † 12 November 1993), known as " Ted" called, was an Australian experimental geophysicists and geochemists. He received in 1988 the highest award of the Geological Society of London, the Wollaston Medal.

The mineral ringwoodite was named after Ted Ringwood, in recognition of his work with under geologically low pressure resulting germanate minerals as a substitute for incurred under high pressure polymorphic silicate minerals. The results of the experiments as allowed him to predict that polymorphic phase transitions in the frequently occurring in the mantle minerals olivine and pyroxene are already taking place in the transition zone. At the Australian National University, he began experimental studies of silicates under high pressure, and was able to show in 1959 that the iron-rich end member of the solid solution series of olivine actually had to convert to the denser spinel structure, such as a number of solid samples of germanates and germanate - silicates already shown had. In 1966 Ringwood and Alan Major, 1964-1993 his technical staff, the synthesis of the spinel structure of (Mg, Fe) 2SiO4, and in the same year, the transformation of pure forsterite ( Mg2SiO4 ) in the spinel structure. This mineral was named after him.

1978 and his team at the Australian National University SYNROC the process, may be a way for the safe storage and disposal of radioactive waste.

Ringwood died on 12 November 1993 at the age of 63 years to lymphoma.
