Monazite - Wikipedia Monazite is a primarily reddish-brown phosphate mineral that contains rare-earth elements Due to variability in composition, monazite is considered a group of minerals [ 3 ] The most common species of the group is monazite-(Ce) , that is, the cerium-dominant member of the group [ 4 ]
Monazite: A rare-earth phosphate mineral. - Geology. com 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
Monazite Group: Mineral information, data and localities. - mindat. org The great majority of "monazite" is monazite-(Ce), the La-, Nd-, Sm- and Gd-dominant members are all very rare Monazite usually contains small amounts of Th or sometimes U, both making it radioactive, and making it very useful for geochronology
Monazite | Rare Earth Elements, Thorium Phosphate | Britannica Monazite, phosphate mineral, cerium and lanthanum phosphate, (Ce, La)PO4, that is the major commercial source of cerium Occurring as small, brown, resinous, rather heavy crystals in granitic and gneissic rocks and their detritus (called monazite sands), monazite frequently contains 10–12 percent
Monazite - an overview | ScienceDirect Topics Monazite is a phosphate mineral containing approximately 70% REE oxides According to dominant REE contents, monazite is divided into monazite- (Ce), monazite- (La), monazite- (Nd), and monazite- (Sm), and the first type is most common in nature
Monazite- (Ce) Mineral Data From the Greek monazeis - "to be alone" in allusion to its isolated crystals and their rarity when first found Comments: Orange crystals of monazite- (Ce) on lepidolite Location: Conselheiro Pena, Minas Gerais, Brazil Scale: Not Given Warning: this large pop-up is very compute intensive and may not work well with some computers
The monazite Mineral Group - The Mineral and Gemstone Kingdom Monazite- (Ce), the cerium-rich end member, is by far the most common group mineral of this series, and accounts for most of the known specimens and occurrences Monazite is radioactive, and specimens may be metamict with rounded crystal faces
Monazite - Meaning, Formula, Properties, Uses and FAQs - Vedantu Monazite is a rare-earth element-rich phosphate mineral that is predominantly reddish-brown in colour Monzite Formula: The Monazite formula is (Ce,La,Nd,Th) (PO4,SiO4), and in igneous and metamorphic rocks such as granite, pegmatite, schist, and gneiss, it is contained in small isolated grains as an accessory mineral
Monazite - The Most Common Thorium Mineral! - allRadioactive Monazite is a brownish phosphate mineral, primarily known for containing several of the rare earth elements, including Lanthanum, Cerium, and Thorium It scores between 5 0 and 5 5 on the Mohs scale of mineral hardness and has a density of 4 6–5 7 g cm³
Monazite - Northwestern University Monazite is a red green-brownish, waxy mineral It is hard and resistant Monazite is formed when igneous rocks undergo crystallization and when clastic sedimentary rocks undergo metamorphism It is commonly mined in placer deposits, which are masses of loose sediment mainly consisting of sand
