The Bakfjord Granite contains quartz, K-feldspar, biotite, plagioclase, epidote, allanite, muscovite and occasional garnet. |
|
In his 1885 report, Eakins described allanite and gadolinite from the area. |
|
Large titanite euhedra are abundant along with apatite and zircon, with allanite and epidote less so. |
|
Gadolinite and allanite intergrowths form walnut-shaped vitreous black masses and nodules to 5 cm across. |
|
Foord reported that bastnasite has been found pseudomorphing allanite. |
|
Typical accessory minerals include apatite, zircon, fluorite, magnetite, titanite, and allanite. |
|
Schlieren consists of biotite, amphibole, zircon, allanite, monazite, magnetite, and fluorite. |
|
The rare earth mineralization, consisting of fergusonite, allanite, and zircon, occurs in amphibole bearing granitic pegmatites. |
|
These Prospects exhibit REE mineralization consisting of allanite, zircon and fergusonite, associated with felsic volcanic rocks in a mafic-felsic bi-modal volcanic belt. |
|
Allanite, fluorite, perovskite, sphene, and zircon have the potential to be future sources of rare earths. |
|
Allanite, fluorite, topaz, yttrotantalite, and zircon have all been found in pegmatites in the Stove Mountain area. |
