The sample is a reddish buff quartzite composed of round to angular quartz sand grains cemented by quartz (SiO2) with some iron oxide (FeO2, producing the red color) and calcite (CaCO3). This rock is a sedimentary orthoquartzite that has not been subjected to sufficient heat and pressure to recrystallize the rock.
Quartzite is also quarried for paving blocks, riprap, crushed stone, railroad ballast, and roofing granules. In microscopic section the clastic structure of some quartzites is well preserved; the rounded sand grains are seen with quartz overgrowths deposited in crystalline continuity, so that optical properties of the grains are similar to ...
