It is considered to be clastic, meaning it is made up of preexisting rocks and minerals such as sand particles.Quartzite, sandstone that has been converted into a solid quartz rock, free from pores and possessing a smooth fracture. Quartzite, when struck, breaks through, not around, the sand grains. The conversion of sandstone to quartzite may occur by precipitation of silica from interstitial waters below Earth’s surface.Sandstone can be cleaned by manually scrubbing it with a brush and cleaning agent, or it can be washed with a pressure washer.
