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.
