Named for the type locality at Baveno in the Seula mine in Piedmont, Italy. Bavenite is an uncommon mineral that occurs “as druses in miarolitic cavities in granite and associated pegmatites, formed by the alteration of beryl and other beryllium-bearing minerals, [and] also in hydrothermal veins and skarn.” Localities include in, additionally, the Czech Republic, Norway, Switzerland, the United States, Australia, Kazakhstan, Russia, and a number of others. Bavenite is weakly piezoelectric and generates a charge in response to pressure.

A new IMA mineral (IMA 2014-19). The Bavsiite are the glassy bluish crystals to less than 0.5mm and occurs with green Suzukiite.
An uncommon mineral named for the original collector of the first specimens, English physician John Bayldon. It is a rare to uncommon mineral that can be found in localities in England, France, Ireland, Namibia, Kazakhstan, Australia, and the United States, among a few others. Bayldonite occurs as a secondary mineral in oxidized polymetallic deposits. Associated minerals include mimetite, olivenite, azurite, malachite, tsumebite, cuprian adamite, duftite, keyite, schultenite, philipsbornite, beudantite, alglesite, cerussite, and baryte.

Named for Professor William Shirley Bayley, former American mineralogist and geologist at the University of Illinois who also worked for the United States Geological Survey. Bayleyite is a rare mineral that can be found in localities in the United States, Canada, Morocco, Argentina, France, and Israel, among only a few others. It occurs as a coating or efflorescence along with other secondary uranium minerals and may be of post-mine origin, and is found typicality in sediment-hosted uranium deposits. Bayleyite is soluble in water and can rapidly dehydrate when exposed to air. It is quite radioactive and has a weak fluorescence of yellow-green to pastel green under both long-wave and short-wave ultraviolet light.
