Post-magmatic solid solutions of CaCeAl2(Fe3+ 2/3□1/3)[Si2O7][SiO4]O(OH), allanite-(Ce) and REE-bearing epidote in miarolitic pegmatites of Permian Baveno granite (Verbania, central-southern alps, Italy)

Mineralogy and Petrology, 2016
CaCeAl2(Fe3+ 2/3□1/3)[Si2O7][SiO4]O(OH), allanite-(Ce) and rare earth element (REE)-bearing epidote occur as globular aggregates and platy prismatic crystals in miarolitic cavities in a niobium, yttrium, fluorine (NYF) granitic pegmatite at Baveno, Verbania, Southern Alps, Italy.

Allanite-(Ce) alterations in the Mukinbudin Feldspar Quarries pegmatite, Mukinbudin, Western Australia

2014
The Mukinbudin area, Western Australia, comprises a pegmatite field with pegmatite bodies classified as NYF-type [1]. Allanite-(Ce) has been found in Mukinbudin Feldspar Quarries in form of metamict masses. The allanite masses are round-shaped being up to tens of centimeters in diameter and show no distinct crystal faces.

Allanite-(Ce) and epidotes in a feldspar deposit from Central Sardinia, Italy

1993
Epidotes occur in albitites as light rare-earth element (LREE)-bearing accessory common phases.Chemical data suggest that there is a near complete solid-solution between epidote and allanite. In epidote-group minerals a pronounced zoning in REE was observed.

Allanite-(Ce) and rare earth element bearing epidotes in the albitites of central Sardinia (Italy)|Allanite-(Ce) ed epidoti a Terre Rare nelle albititi della Sardegna centrale (Italia)

1996
Recent investigations have pointed out that epidotes and allanite-(Ce) are the main REE-bearing minerals in the albitites located in the granodiorite facies of Central Sardinia. Previous works on albitites hypothesize that they originated from Na and Mg-metasomatic alteration of granitoids.
