Named after George R. Rossman (1945- )

Schorl
NaFe2+3Al6(Si6O18)(BO3)3(OH)3OH
Name probably derived from the early German mining term “Schor” (mud) or
after the name of the former village “Schorl“ (today: Zschorlau) in Saxony, Germany.

Fluor-uvite

Named for the type locality area, Uva Province, Sri Lanka.

Vanadium-dravite
NaMg3V3+6(Si6O18)(BO3)3(OH)3OH
Named for its relationship to dravite and chemical composition.
