Allanite behaviour during incipient melting in the southern Central Alps
, 2012 The response of allanite to incipient melting was investigated in migmatites from the Tertiary Barrovian-type sequence of the Central Alps (southern Switzerland, northern Italy).

The allanite deposits on Vrede, Gordonia District, Cape Province [PDF]
, 1961 Allanite deposits of an unusual nature occur in two types of granulite on the farm. Vrede, portion of Cnydas West, Gordonia District, Cape Province. The granulites belong to the Archaean complex which is also represented by schists and gneisses.

Strain partitioning in host rock controls LREE release from allanite-(Ce) in subduction zones [PDF]
, 2020 Combined microstructural, mineral chemical, X-ray maps, and X-ray single-crystal diffraction analyses are used to reveal the rheological behaviour of individual grains of magmatic allanite relicts hosted in variably deformed metagranitoids at Lago della ...

Allanite in the granite of the north of Scotland [PDF]
Transactions of the Edinburgh Geological Society, 1909 Allanite has been recorded as occurring in a number of the granites of the North of Scotland, but while engaged on a research on these rocks for another purpose, I have discovered its presence in a number of rocks in which it has not previously been recorded. The granites in which it occurs may be enumerated. They are:—(1) Hildesay granite (Shetland); (

Investigation of accessory Allanite, Monazite and Rutile of the Barrovian sequence of the Central Alps (Switzerland) [PDF]
, 2018 Accessory Allanite, Monazite and Rutile from amphibolite facies rocks across the Barrovian sequence of the Central Alps (Switzerland) were investigated for textural relationships, composition and U-Th-Pb ages.

Journal of Metamorphic Geology, EarlyView.ABSTRACT Zircon is a common, highly refractory accessory mineral found in sedimentary, igneous and metamorphic rocks that forms through various processes (e.g., magmatic, hydrothermal, metamorphic growth and recrystallization). Trace element compositions of detrital zircon have been widely applied to understanding tectonic processes and continental ...
