Are feldspar and quartz carbonates?

Feldspar and quartz are not carbonates (carbonate minerals). They are silicates because they have Silica (Si) in the formula. Quartz is SiO2. Feldspar is a mineral group (feldspars) They have a variable composition that gneerally depends on the amount of Ca, Na or K in their chemical formula. An example of feldspar is Albite NaAlSi3O8. Carbonates have CO3 in their chemical formula. Two examples are Calcite (CaCO3) and Siderite (FeCO3).
