Robert M. Garrels
Formula:
Ba3NaSi2B7O16(OH)4
Colour:
colourless
Lustre:
Vitreous
Hardness:
6
Crystal System:
Monoclinic
Name:
Named by C. Milton, J.M. Axelrod, and F.S. Grimaldi in 1955 in honor of Robert Minard Garrels (24 August 1916, Detroit, Michigan, USA – 8 March 1988, St. Petersburg, Florida, USA), geochemist. He was Chief, Solid State Group, Geochemistry and Petrology Branch, U. S. Geological Survey, when the mineral was discovered. He also was a professor at several institutions including Northwestern, Harvard, and U. Hawaii. His work on aqueous geochemistry was revolutionary. He was the recipient of several awards including the Penrose, Wollaston, and Roebling Medals.
Minute dipyramidal crystals.
