How Is Quartz Formed? | Our Pastimes

Quartz can be formed naturally from the silica which collects in the earth. When silicon (Si) and oxygen (O2) combine, it will create silicon dioxide (SiO2), which is quartz. For this reason, quartz will form underground quite easily whenever a combination of oxygen and silica-rich solutions are present.

Sandstone - Wikipedia

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series.
