Rockhound. Sandstone is a sedimentary rock composed of cemented weathered grains of rock, most abundantly, quartz grains from granite. Quartzite is metamorphosed sandstone, the product of intense pressure and heat which has caused the individual grains to recrystallize into larger crystals which are interlocked.uartzite is the metamorphic product of sandstone. During metamorphism, intense heat and/or pressure cause the quartz grains contained in the sandstone grow and recrystallize, â¦ interlocking together creating Quartzite. 4 people found this useful.
Gneiss can be formed from a sedimentary rock such as sandstone or shale, or it can be formed from the metamorphism of the igneouse rock grantite. Gneiss can be used by man as paving and building stone. Quartzite is composed of sandstone that has been metamorphosed. Quartzite is much harder than the parent rock, sandstone. It forms from sandstone that has come into contact with deeply buried magmas. Quartzite looks similar to its parent rock. The best way to tell quartzite from sandstone is to break the rocks.
