Monazite is a primarily reddish-brown phosphate mineral that contains rare-earth elements. Due to variability in composition, monazite is considered a group of ...
This variety of monazite is typically colored bright rose-red. It is the neodymium analogue of monazite-(Ce) , monazite-(La) , and monazite-(Sm) . [ 4 ] The group contains simple rare earth phosphate minerals with the general formula of A T O 4 , where A = Ce, La, Nd, or Sm (or, rarely, Bi), and B = P or, rarely, As.
Bastnäsite crystal from the Manitou District, El Paso County, Colorado, USA (size: 4.3×3.8×3.3 cm) Bastnäsite has cerium, lanthanum and yttrium in its generalized formula but officially the mineral is divided into three minerals based on the predominant rare-earth element. [6] There is bastnäsite-(Ce) with a more accurate formula of (Ce ...
Monazite-(La) is a relatively rare representative of the monazite group, with lanthanum being the dominant rare earth element in its structure. As such, it is the lanthanum analogue of monazite-(Ce) , monazite-(Nd) , and monazite-(Sm) .
Old School RuneScape is a massively multiplayer online role-playing game (MMORPG), developed and published by Jagex.The game was released on 16 February 2013. When Old School RuneScape launched, it began as an August 2007 version of the game RuneScape, which was highly popular prior to the launch of RuneScape 3.
It is the cerium-dominant analogue of monazite-(La), monazite-(Nd), and monazite-(Sm). It is also the phosphorus analogue of gasparite-(Ce). [ 3 ] The group contains simple rare earth phosphate minerals with the general formula of AXO 4 , where A = Ce, La, Nd, or Sm (or, rarely, Bi), and X = P or, rarely, As.
Monazite geochronology is a dating technique to study geological history using the mineral monazite. It is a powerful tool in studying the complex history of metamorphic rocks particularly, as well as igneous, sedimentary and hydrothermal rocks. [2] [3] The dating uses the radioactive processes in monazite as a clock.
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). [3]
