  • Tridymite

    Compared with other silica polymorphs, dense packing of the crystal structure and high activation energy required to alter the Si-O-Si bond are major factors contributing to the high stability of quartz. Quartz is present in essentially all soils and often constitutes the major portion of all sand and silt fractions.
