CaFeSb(AsO3)2O
Colour:
Bright reddish orange
Hardness:
4
Specific Gravity:
4.63
Crystal System:
Tetragonal
Name:
From Swedish "stenhuggare", meaning "stone mason", for Dr. Brian Harold Mason (18 April 1917, Port Chalmers, New Zealand – 3 December 2009, Washington D.C., USA), a New Zealandic-American geochemist, mineralogist, and meteoriticist. He graduated from Canterbury University, New Zealand. He served as a Curator of Mineralogy at the American Museum of Natural History in New York, and as Curator of Meteorites at the Smithsonian Institution, Washington, D.C. He was a proponent for the systematic collection of meteorites and studied moon rocks. He was a recipient of the Leonard Medal and the Roebling Medal. The mineral brianite is also named for him.
