Mineralpedia Details for Bromargyrite
Bromargyrite
Named for the bromine in the composition as well as the silver content after the Greek word for “silver,” argyros. Bromargyrite is an uncommon mineral, but rare at its localities which can be found in France, Germany, the United States, Mexico, Chile, and Australia, among several others. I toccurs in oxidized silver deposits, particularly in arid regions, in association with silver, iodargyrite, smithsonite, and iron-manganese oxides. Upon exposure to air, Bromargyrite may give off a strong scent with a ‘medicinal’ quality to it. Waxy, sectile typically formless crystals of pale yellow, greenish brown, bright green.
