Sandstone or chert that is quartz-rich
that has been subjected to high temperatures and pressures can metamorphose
into quartzite stones. Quartz content and interlocking grain structure are two
characteristics of quartzite. These are a solid rock that can withstand
abrasion and the elements. Among their many applications are as a building
material, decorative stone, and abrasive. For metallurgical uses and the
production of silica brick, pure quartzites provide a source of silica. Quartzite
stones are a type of natural stone that is created from mountainous debris. These
are a very sturdy and long-lasting stone that is ideal for building and
landscaping projects.
