What minerals make up sandstone.

Sandstone is a type of sedimentary rock. It is considered to be clastic, meaning it is made up of preexisting rocks and minerals such as sand particles. Sandstone can also be made up of larger clasts and fragments that overtime have been cemented together. Sandstone is primarily made up of quartz and to a lesser degree feldspar due to their ...Quartzite is a metamorphic rock derived from sandstone that is distinguished from sandstone by its fracture. Sandstone breaks along grain boundaries, whereas quartzite is so well indurated (hardened) that it breaks across constituent grains. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly ...Quartzite is a very hard rock composed predominantly of an interlocking mosaic of quartz crystals. The grainy, sandpaper-like surface is glassy in appearance.
