..., quartzite, magnesite-serpentinite, quartz-phlogopite108 hematite schist, quartzite, and sillimanite mica schist (Jøsang 1966). The Dypingdal upper quarry 109 is located 500 m north of lake Dypingen in the magnesite-serpentinite deposit (Fig. 2A). White 110 hydrous Mg carbonates were only found...

...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...

... hydrotalcite has been known since 1842, when it was first described by Hochstetter ( 1842 ) in material from the Dypingdal serpentine–magnesite deposit in Snarum, Modum, Buskerud, Norway (Mills et al. , 2016 ). As well as existing as minerals, LDHs are often prepared synthetically, owing to their wide range...

... .4H 2 O, is much rarer than hydromagnesite. It was first described by Raade (1970 ) as an alteration product encrusting serpentine at the Dypingdal serpentine-magnesite deposit at Snarum, Norway, and has subsequently been reported from a handful of generally similar environments. The only previously...

... breccia is a carbohydrothermal deposit, the product of a low temperature (<450°C), highly evolved, alkaline, SiO 2 -undersaturated, Na–Ba–REE–Cl-rich, residual carbonated silicate melt whose parental origins remain unknown. * Author for correspondence: Paula C. Piilonen, Email: ppiilonen...
