environments not conducive to optimum coral growth, is conducive to quartz sandstone.
The principal mineral in sandstone is quartz. Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles, with quartz being the most abundant mineral present.

Generally, arkosic sandstone would travel less distance before deposition compared to quartz sandstone. This is because arkosic sandstone is typically less resistant to weathering and erosion due to its higher content of feldspar, which weathers more easily compared to quartz. Quartz sandstone, being more durable, can travel further before getting deposited.
rock salt and conglomerate
how about u give me the answer
Maybe lechatelierite? Or crystal (as in quartz glass)?
Sandstone is usually composed of grains of quartz with a calcitic or silica based cement.

Metamorphic quartz sandstone is a type of sedimentary rock that has undergone metamorphism, resulting in a denser, harder rock. This process typically involves heat and pressure that recrystallizes the quartz grains and other minerals in the sandstone, transforming it into a more compact and durable rock. Metamorphic quartz sandstone usually exhibits distinct banding or foliation due to the rearrangement of mineral grains during metamorphism.
QUARTZ SANDSTONE
Pure quartz is a colorless mineral, and so a pure quartz sandstone will appear white due to multiple reflections and refractions between grains. However, impurities in the sandstone may give it some other color. What color it turns out as depends on the impurities. For example, iron oxide will produce a red sandstone.
Sandstone has no defined chemical formula. Sandstone is usually composed of quartz grains sometimes cemented together with a variety of minerals. The quartz grains are composed of SiO2 (Silicon dioxide). The cement in a sandstone are often composed of quartz (SiO2) or calcite (CaCO3) or rarely, other minerals.
