Application & Specifications


What Is Quartzite?

Quartzite is a metamorphic rock converted from sandstone through high heat and pressure. With a hardness of 7 on the Mohs Scale, quartzite is one of the most durable building materials, showing little wear over time. It is non-porous and highly resistant to staining, color fading, and flaking caused by frost or freezing. Quartzite is nearly maintenance-free.


Mt. Moriah Quartzite

The Mt. Moriah quartzite deposit has an extensive history behind it.


In the original Bonneville Lakebed, deposits of sedimentary rock were subjected to tremendous heat and pressure causing a complete re-crystallization into layers of quartzite and coarse-grained mica schists. Quartzite containing mica breaks into flat, even layers along seams, a property called cleavage. This allows the quartzite to be quarried and split into naturally dimensional flagstone, ledger, rectangular builders, mantles, benches, hearthstones, and steps; along with unusually large flagstone uniquely suited for indoor/outdoor tabletops; and uncommonly large slabs and blocks for feature landscape and waterfalls. Streambed sections of the claim yield naturally rounded quartzite boulders, pancake, and creek ledger. Other non-quartz minerals from the original sedimentary rock have retained their form, showing a variety of beautiful patterns and coloration in the quartzite.


According to Richard Hose, USGS, stone similar to the Mt. Moriah Quartzite is known to occur in only a few other isolated locations in the entire world, and it is likely the largest straight-edge, natural slab, and ashlar flag deposit in the United States. Mt. Moriah Stone claims include 1200 acres of prime quartzite, layered 300 to 1500 feet deep, sufficient to supply the stone and building industry for hundreds of years.


Mt. Moriah quartzite’s range of colors: Earth tones of varied gray, blue-gray, brown, and cream are highlighted with silver, white, gold, peach, orange, rust, red, mauve, and deep charcoal, flecked with pinpoints of glistening mica schist.

The stone is palletized as quarried, producing distinctive, multi-blend coloration.
