  • 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.
