  • Monazite-(Sm) - Wikipedia

    en.wikipedia.org/wiki/Monazite-(Sm) Monazite-(Sm) is an exceedingly rare representative of the monazite group, with samarium being the dominant rare earth element in its structure. It is the samarium analogue of monazite-(Ce), monazite-(La), and monazite-(Nd).It is only the second known mineral with samarium being the mineral-forming element, after florencite-(Sm). The group contains simple rare earth phosphate minerals with the ...
  • Monazite: A rare-earth phosphate mineral.

    geology.com/minerals/monazite.shtml 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.

  • Samarium - Wikipedia

    en.wikipedia.org/wiki/Samarium Samarium is a chemical element with the symbol Sm and atomic number 62. It is a moderately hard silvery metal that slowly oxidizes in air. Being a typical member of the lanthanide series, samarium usually assumes the oxidation state +3. Compounds of samarium(II) are also known, most notably the monoxide SmO, monochalcogenides SmS, SmSe and SmTe, as well as samarium(II) iodide.
