Sandstone - Wikipedia

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20-25% of all sedimentary rocks.. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities ...

However, what is surprising is that angular K-feldspar grains can often be found intermixed with better rounded quartz grains (Fig. 6). On Mohs scale of hardness, K-feldspar has a hardness of 6.0, and quartz has a hardness of 7.0. K-feldspar is also less resistant to abrasion than quartz based on experiments by Thiel (1940).
