Sandstone mineral.

Quartz is the most common mineral found in sandstone, making up over 50% of its composition in many cases. It is a hard, durable mineral resistant to weathering, and its abundance in sandstone is a testament to its ability to withstand erosive forces. As a result, quartz-rich sandstones are generally strong and resistant to weathering, making ...
