Continental sand

Continental sand, as its name says, is the most dominant sand type on the continental beaches. We are probably all (with few exceptions) very familiar with this buff grainy material that is mostly composed of quartz but may also contain other minerals like feldspar, mica, and biogenic grains. However, none of them are not nearly as abundant as quartz.

This sand is usually yellow or light brown and often speckled with dark grains. It is common along passive continental margins (without active volcanism).

Continental sand from Botany Bay, Sydney, Australia.
