During millions of years, under great heat and pressure, original Bonneville Lake bed sandstones were completely re-crystallized to quartzites and the intervening shales were converted to coarse-grained mica schists. According to the Gans and Miller Report (Department of Geology, Stanford University), mineralogically this quartzite consists of five to fifteen percent microcline (feldspar), ten percent muscovite (light colored platy mica mineral), and the balance quartz. Muscovite forms the foliation visible in the natural cleft surfaces. This stone is almost perfectly foliated (lamellar or plate-like), having uniform thickness from two to ten centimeters or more when quarried. Additionally, surfaces are flat, not warped. With a hardness of 6 - 7 on the Mohs scale, quartzite is one of the most durable building materials, exhibiting negligible wear over time. It is non-porous, highly resistant to staining, color fading, and flaking caused by frost and freezing. Quartzite, is for all practical purposes, maintenance free.
