Adsorption of octylhydroxamate on monazite.

open access: yesShigen-to-Sozai, 1989
Adsorption isotherms of octylhydroxamate and the relationship between octylhydroxamate adsorbed and phosphate released have beenmeasured against monazite. These results have been compared to those against synthetic CePO4and LaPO4. Adsorption of hydroxamate on monazite takes as long as several daysto reach equilibrium.

Monazite LA-ICP-MS U-Pb Dating to Constrain the Metamorphic Age of the Muzidian Gneiss Complex in the Northern Dabie Orogen

open access: yesYankuang ceshi
The Muzidian gneiss complex (MGC) in the Northern Dabie Orogen is the oldest exposed rock formation in the South China block. However, there is still a lack of research on its metamorphic age and tectonic implications.

Stability and isotopic dating of monazite and allanite in partially molten rocks: examples from the Central Alps [PDF]

open access: yes, 2018
We investigated the stability of monazite and allanite as a function of bulk rock composition within several types of Tertiary Alpine anatexites, characterized by different compositions and melting reactions, but similar P-T conditions of melting.
