Sand grain cards are used as a quick tool for determining sand grain size, sorting, and shape during field analysis (Fig. 5.25). Sand grain cards allow scientists to easily determine sand size in the field according to the Wentworth scale. Scientists compare the sand at their field site to the pictures (on the left of the card in Fig. 5.26).

High-purity quartz (HPQ, SiO 2) is an important material widely used in semiconductor technologies, high temperature lamp tubing, thin-film transistor-liquid crystal display (TFT-LCD), telecommunications, and optics []mon quartz ores (vein quartz, quartz sandstone, etc.) inferior to crystal-grade quartz have been used to prepare HPQ …
Quartz is the most important sand-forming mineral and occurs in very many sand types but usually not exclusively. In this sand type (which is aptly named quartz sand), quartz is almost the sole component of sand. Similar sandstones are called quartz arenites or orthoquartzites..

Orthoclase and quartz would persist longer, but the grains of quartz would have the greatest chance of survival. They are more chemically inert, harder, and not prone to cleavage. Quartz is often the most abundant type of sand grain present in sandstone. It is abundant in source materials and is the most durable during transport.

Sandstone is a sedimentary rock composed mostly of quartz sand, but it can also contain significant amounts of feldspar, and sometimes silt and clay. Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone.
