Formula:
Mn2+3Mn3+(AsO4)(OH)6
Lustre:
Sub-Vitreous, Resinous, Greasy

Orthorhombic
Name:
Named in 1982 by Pete J. Dunn, Donald R. Peacor, Peter B. Leavens, and William B. Simmons in honor of Eugene Jarosewich [January 6, 1926 - April 30, 2007 Washington, District of Columbia, USA] mineral and meteorite chemist, Department of Mineral Sciences, Smithsonian Institution. Jarosewich established analytical standard materials for microprobe analysis and established analytical standard materials for meteorites.
Dark brown tightly intergrown cushion-like to divergent clusters of crystals.
