Name:
Named by Cornelius S. Hurlbut in 1936 in honour of Dr. Harry Berman [February 16, 1902 Boston, Massachusetts, USA - August 27, 1944 Prestwick, Scotland], co-author of seventh edition of Dana's System of Mineralogy, systematic mineralogist, early classifier of the structures of silicates, Professor of Mineralogy, Harvard University, Cambridge, Massachusetts, USA.


A late-stage secondary hydrothermal mineral replacing primary phosphate species.

Structurally related to ercitite and coralloite (chemically the arsenate analogue of bermanite).
