Alteration product that forms partial to almost complete pseudomorphs after lamellar crystals of eudidymite. New structure type.
Approved IMA 2007 (Dana # Added)
Poudrette quarry, Mont Saint-Hilaire, Rouville County, Quebec, Canada. Link to MinDat.org Location Data.
Named from Latin niveus, snow-white, and lana, wool, alluding to the visual similarity of its aggregates to snow-white, fluffy flocks of wool.
