Russell J. Hemley
Formula:
Fe2+SiO3
Specific Gravity:
4.383 (Calculated)
Crystal System:
Trigonal
Member of:
Ilmenite Group
Name:
Named in honour of Russell J. Hemley (b. 1954), former Director of the Geophysical Laboratory of the Carnegie Institution of Washington D.C., USA, and very well-known in the scientific community for his research exploring the behavior of materials under extreme conditions of pressure and temperature.
High-pressure phase, discovered in an unmelted portion of the heavily shocked L6 Suizhou chondrite. Fe(II)-analogue of akimotoite. Ilmenite-type structure.
