Quartz Sand Sandatlas

Quartz sand. Sand that is enriched in quartz is likely old (mature) and has traveled far from the source area, sometimes thousands of kilometers. Long journey is required to allow weathering to break down weaker minerals that were initially present in the rocks.

    Weathering and Transport of Sand. 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 typically the most abundant type of sand grain present in sandstone. It is extremely abundant in source materials and is extremely durable during transport.
