Thermochemistry of monazite-(La) and dissakisite-(La): implications for monazite and allanite stability in metapelites [PDF]
, 2018 Thermochemical properties have been either measured or estimated for synthetic monazite, LaPO4, and dissakisite, CaLaMgAl2(SiO4)3OH, the Mg-equivalent of allanite. A dissakisite formation enthalpy of −6,976.5±10.0kJmol−1 was derived from high-temperature
