👉 Quartzous is a geological term used to describe rocks that are composed mainly of quartz. Quartz is a group of minerals that have distinct chemical and physical properties, including their crystal structure and dispersion. The word "quartz" comes from the Greek word "quarta," which means "third" or "fourth." Therefore, quartzous can also be interpreted as having three main components: quartz (a single mineral) and other minor elements such as feldspar and lysite.
