Recrystallization of metamict allanite

Mineralogical Magazine, 2011
AbstractAllanite is a common accessory mineral in igneous rocks. Allanite becomes metamict over geological time-scales as a result of the α-decay of radioactive elements in the crystal structure. This study focuses on the recrystallization of metamict allanite from Savvushka, Russia.

PIXE analysis of allanites

Journal of Radioanalytical and Nuclear Chemistry Articles, 1990
Allanites from Telixtlahuaca (Oaxaca, Mexico) were analyzed using the PIXE technique. The concentrations of 12 elements, mainly rare earths, were determined.

THE HYDROTHERMAL RECRYSTALLIZATION OF METAMICT ALLANITE-(Ce)

The Canadian Mineralogist, 2010
Samples of metamict allanite-(Ce) originating from granite pegmatites were recrystallized by heating in air and under hydrothermal conditions. Recrystallization in air resulted in partial recovery of the crystal structure at 650°C. Heating at higher temperatures resulted in decomposition of the allanite structure to a multiphase assemblage containing ...
