quartz and feldspar are common rock forming
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).

Feldspar
Aluminum is an element; it cannot be decomposed further using chemical techniques. Feldspar is a family of alumino-silicate minerals, which can be broken down by strong acids.
The group of minerals in Feldspar contain framework tectosilicates. The compositions of the major elements in the usual feldspars can be identified by three endmembers: Potassium-Feldspar, Albite, and Anorthite.
Feldspar breaks down giving us Al, Si and O in solution. You also get clay minerals left behind.
