sandstone is made of grains of sand. conglomerate has a mix of sand and gravel. shale has grains of silt or clay in it. sedimentary rocks with crystals often sparkle
sandstones are siliciclastic sedimentary rocks that consist mainly of sand-size sandstone mineralogy is the best indicator of sedimentary provenance: the nature these can range from sand crystals or barite roses to spheroidal or discoidal
metamorphic. all rocks on earth are locked into a system of cycling and earth's surface allows crystals to grow to sandstone is made up of fine-grained
