Dypingdal serpentin-magnesittforekomst (Dypingdalsgruvene), Snarum, Modum kommune, Buskerud fylke, Norge

Small serpentine-magnesite bodies that occur in precambrian rocks. They have been quarried for magnesite and serpentine.

Note on the mineral list:
The so-called "martite" from here is actually hematite (Raade, 1982).
