What is the Difference Between Feldspar and Quartz

2023年6月25日 The main difference between feldspar and quartz is that feldspar consists of a framework of aluminum, silicon, and oxygen atoms, with additional elements such as potassium, sodium, or calcium.In contrast, quartz consists solely of silicon and oxygen atoms (silica). Feldspar and quartz are both minerals commonly found in the Earth’s crust.
