Named by Paul (Paulus) Brian Moore in 1967 in honor of Swedish mineralogist, Olof Erik Gabrielson (December 10, 1912 Örebro, Sweden - January 28, 1980) who was at the University of Stockholm and later at the Swedish Museum of Natural History.

Type Locality:

ⓘ Långban, Filipstad, Värmland, Sweden

Adelite-Descloizite Group.

The crystal structure is unsolved; it appears to be microtwinned (U. Kolitsch, unpubl. results).

IMA proposal 17-G was accepted and the former formula, PbFeAsO₄(OH), was changed. It makes the mineral an arsenite instead of an arsenate.
