Adsorption of octylhydroxamate on monazite.
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.

Accretionary origin for the late Archean Ashuanipi Complex of Canada [PDF]
The Ashuanipi complex is one of the largest massif granulite terrains of the Canadian Shield. It makes up the eastern end of the 2000 km long, lower-grade, east-west belts of the Archean Superior Province, permitting lithological, age and tectonic ...

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