Background. Quartzite is originally sandstone that undergoes metamorphism via intense heat and pressure. The quartz grains are highly compacted resulting in a dense rock. Quartzite has a high degree of quartz -- 90 percent or more -- and is the most concentrated, purest form of silica found on Earth. They tend to form when continents collide ...Sandstone starts out as humble beach sand. Eventually, sand gets buried and compressed by overlying layers, and minerals carried by groundwater act as glue that binds the sand grains together into solid rock.
