It is a silicon dioxide crystal. The smoky color results from free silicon formed from the silicon dioxide by natural irradiation. What is Quartzite. Quartzite is a type of metamorphic rock made of quartz (King, 2019). This means that to form quartzite, it started as quartz and overcame changes from high pressure or heat over a long period of time that are physical and or chemical. An important characteristic of quartzite is that it is tough and durable (King, 2019).

Quartzite is a metamorphic rock that is formed by interlocking quartz grains from quartz sandstone. The rock is hard rock, nonfoliated.

Let’s now see what type of rock is quartzite by answering the first question: is quartzite foliated or nonfoliated? Quartzite mineral is a non-foliate metamorphic rock, derived primarily from quartz sandstone through a process of heating and pressure. Shale rocks are those that are made of clay-sized particles and are have a laminated appearance. They are a type of sedimentary rock. Shale is the abundant rock found on Earth. They are usually found in areas where gentle waters have deposited sediments that become compacted together. Shale usually forms in sheets. Quartz has attracted attention from the earliest times; water-clear crystals were known to the ancient Greeks as krystallos—hence the name crystal, or more commonly rock crystal, applied to this variety. The name quartz is an old German word of uncertain origin first used by Georgius Agricola in 1530. A brief treatment of quartz follows. Quartzite. Rock group, Metamorphic.
