The answer is: calcite and dolomite.
Non-silicate minerals are minerals that do not retain the silica tetrahedron. Carbonated anion is CO₃²⁻.
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO₃).
Dolomite is a carbonate mineral composed of calcium magnesium carbonate (CaMg (CO₃) ₂).
