About Gabrielsonite
Formula:
PbFe3+(As3+O3)O
Colour:
Greenish-brown, black
Lustre:
Adamantine
Hardness:
3½
Specific Gravity:
6.67
Crystal System:
Orthorhombic
Name:
Named by Paul (Paulus) Brian Moore in 1967 in honor of Swedish mineralogist, Olof Erik Gabrielson (December 10, 1912 Ărebro, Sweden - January 28, 1980) who was at the University of Stockholm and later at the Swedish Museum of Natural History.
IMA proposal 17-G was accepted and the former formula, PbFe(AsO4)(OH), was changed. It makes the mineral an arsenite containing trivalent Fe instead of - as originally assumed - an arsenate containing divalent Fe.
Related to the Adelite-Descloizite Group.
Related to the Adelite-Descloizite Group.
