What rock is magnesite found in?

Magnesite is a magnesium carbonate mineral (MgCO3). Unlike related carbonates calcite (CaCO3) and dolomite (CaMg(CO3)2), it is not a major rock-forming mineral. It most commonly occurs in metamorphosed igneous rocks which are rich in magnesium. These are ultramafic rocks like dunite, pyroxenite and peridotite.
