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).
A steel nail can scratch feldspar but not quartz. Feldspar has a hardness of 6 on the Mohs scale, while quartz has a hardness of 7.
Quartz and feldspar are two common minerals that form rocks. Quartz is often found in granite while feldspar is found in both granite and basalt.
Apatite is a mineral that can scratch feldspar but not quartz. This is because apatite has a higher hardness value than feldspar but a lower hardness value than quartz on the Mohs scale of mineral hardness.
Another name for quartz is rock crystal.
The abundance of quartz and shortage of feldspar in most soil can be attributed to the weathering process. Quartz is more resistant to weathering compared to feldspar, which makes it more prevalent in soil. Over time, feldspar weathers into clay minerals and other components, leading to its lower presence in soil compared to quartz.
Silicates are minerals containing silicon and oxygen, such as quartz and feldspar. Carbonates are minerals containing carbonate ions, such as calcite and dolomite. Oxides are minerals containing oxygen and a metal, such as hematite and magnetite.
A steel nail can scratch feldspar but not quartz. Feldspar has a hardness of 6 on the Mohs scale, while quartz has a hardness of 7.
Quartz and feldspar are commonly found together in granite and gneiss.

Quartz
Orthoclase feldspar has a hardness of around 6 on the Mohs scale. This means it is moderately hard and can scratch softer materials but can also be scratched by harder materials.
