Dypingite, a new hydrous basic carbonate of magnesium, from Norway Available to Purchase

Gunnar Raade
Published: 01 October 1970
American Mineralogist (1970) 55 (9-10): 1457–1465.
...Gunnar Raade Abstract The new mineral dypingite was found in the Dypingdal serpentine-magnesite deposit, Snarum, South Norway, where it occurs as a thin cover on serpentine. It is of late secondary origin, deposited from cold, leaching solutions. Chemical analysis of 100 mg of handpicked material...

FT-IR spectrum of the 60°C surface film. The infrared spectra of dypingite and hydromagnesite are extensively similar (Raade 1970; White 1974). Absorption bands resulting from OH- groups ( 3650 cm–1) and water of crystallization (3510 and 3450 cm–1) are identical for both, as are CO32- stretching bands (1480, 1420, and 1120 cm–1) and CO32- bending bands (880 and 850 cm–1).
