Its type locality is the Dypingdal serpentine-magnesite deposit, Snarum, Norway. Synthetic dypingite is known as heavy magnesium carbonate.
It is found in the hardened cement paste of low-{{CO2|link=Carbon dioxide}} footprint MgO-cements after their hydration.<ref name="Zhou2026">{{Cite journal |last=Zhou |first=Zeyu |last2=Bernard |first2=Ellina |last3=Rentsch |first3=Daniel |last4=Lothenbach |first4=Barbara |date=2026-08-01 |title=Hydration and strength development of MgO-nesquehonite-metakaolin binders |url=https://www.sciencedirect.com/science/article/pii/S0008884626001146 |journal=Cement and Concrete Research |volume=206 |article-number=108245 |doi=10.1016/j.cemconres.2026.108245 |issn=0008-8846}}</ref>
