Monazite: A rare-earth phosphate mineral.

What is Monazite? Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th)(PO 4,SiO 4).It usually occurs in small isolated grains, as an accessory mineral in igneous and metamorphic rocks such as granite, pegmatite, schist, and gneiss.These grains are resistant to weathering and become concentrated in soils and sediments downslope from the host rock.

Locations of Deposits

Almost all phosphorus is mined as phosphate rock (PO4). Deposits are typically found in shales, cherts, limestone, dolomites and sandstone as well as hydrothermal veins or as chemically dissolved phosphate minerals in igneous and metamorphic rocks. One of the world's largest phosphate deposit is the Phosphoria Formation, located in southeast Idaho.
