Quartz is a primary mineral.A clay mineral is hydrous aluminum phyllosilicates, usually form in the presence of water. An illite is a group of closely related non-expanding clay minerals.
Sedimentary rock are formed from the deposits of pre-existing rocks or pieces of the once-living organism that accumulate on the Earth's surface. Sandstone is a clastic sedimentary rock.
