What type of rock is dolomite?

Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate ideally CaMg(CO3)2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite.

What kind of rock is magnesite?

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.
