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.
Sandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust.Like sand, sandstone may be any color, but the most common colors are: tan, brown, yellow, red, grey, pink, white, and black.Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions.ike sand, sandstone may be any color, but the most common colors are: tan, brown, yellow, red, grey, pink, white, and black.
