In molecules, elements are not merely mixed together, but are joined by chemical bonds. Chemical bonds in minerals are of four types: covalent, ionic, metallic, or Van der Waals, with covalent and ionic bonds most common. Two or more of these bond types can and do coexist in most minerals. Covalent bonds are very strong bonds formed when atoms share electrons with neighboring atoms. Sulfur, and both of carbon's natural forms, graphite and diamond, are covalently-bonded minerals. So is quartz, which contains only silicon and oxygen.
2. If you consider it as one mineral, feldspar is the most common mineral and quartz comes in second, especially when you consider the whole crust, continental plus oceanic crust. Feldspar is called a group of minerals only for the convenience of geologists.o in the Earth's crust, feldspar in the most common mineral. BUT, 3. The Earth consists of a very thin rocky crust on top of a very thick rocky mantle. Compared to the mantle, the crust is small enough to ignore. And the most common mineral in the mantle is olivine, or at least the compound (Mg,Fe) 2 SiO 4.
