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).
What else can I help you with?
Which object can scratch feldspar but not quartz?
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.
Name two minerals that form rock?
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.
What mineral can scratch feldspar but not quartz?
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.
What is another name for quartz?
Another name for quartz is rock crystal.
How do you account for the abundant of quartz and shortage of feldspar in most soil?
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.
What are all the silicates carbonates and oxides?
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.

What mineral is not scratched with feldspar and the mineral doesn't powder or wear down the feldspar?
Quartz
How hard is orthoclase feldspar?
On the Mohs Scale of mineral hardness, feldspar is 6 and quartz is 7, so quartz is harder. What does this mean? quartz will scratch feldspar, but feldspar will not scratch quartz.
