No, quartz is not a sedimentary rock. Rather, it is classified as a mineral, and it is primarily made up of silicon dioxide (SiO2). Quartz is one of the most abundant and widely distributed minerals found in the Earth’s crust.
Sedimentary rocks are formed through the accumulation and cementation of mineral and organic particles over time. While quartz can be found in sedimentary rocks, such as sandstone, it itself does not qualify as a sedimentary rock. Instead, it serves as a significant component of many sedimentary formations.
In summary, quartz is a mineral that can be part of sedimentary rocks but is not a sedimentary rock in its own right.
