The energy spectra for a large number of NORM samples were measured, including: slate, cat litter, ice melt, roofing tiles, hay, coal, fertilizer, Australian zircon sand, diammonium phosphate (DAP), ISG Pye, CEMEX type FC, monocalcium phosphate (biofos), allanite
, monazite, pyrochlore and zircon.
The results to date have indicated that the light rare earths (LREE) in the Nechalacho deposit are contained in four minerals: allanite
, monazite, bastnaesite and synchisite, and the heavy rare earths (HREE) are present in two minerals: fergusonite and zircon, the latter also being host to zirconium (Zr).
Mineralogical work completed by the company indicated that a wide variety of rare-earth element-bearing minerals have been identified, including apatite, iimoriite, kainosite, gadolinite, allanite
, bastnaesite, parisite, brannerite, thalenite, xenotime, fergusonite, synchysite (Y), and monazite.

He was (perhaps) responsible for large parts of the libretto, "The Magic Flute", but he also discovered many new mineral species including sodallite, allanite
, and gieseckite, was responsible for exploring both eastern and western Greenland, and provided assistance in the planning of several arctic voyages to the Northwest Passage.
The REE in clastic sediments are concentrated in detrital accessory minerals, mainly phosphates (notably monazite and apatite for LREE and xenotime for HREE), minor silicates (notably allanite
, titanate, and zoisite for LREE, garnet and zircon for HREE), and adsorbed to clays (especially HREE).
Athol, for example, is noted for allanite
5) Fission tracks are produced in minerals that contain trace amounts of uranium, such as zircon, apatite, titanite, allanite
, garnet, and micas as well as in U-bearing silicic volcanic glasses.
Typical accessory minerals include apatite, zircon, fluorite, magnetite, titanite, and allanite
Schlieren consists of biotite, amphibole, zircon, allanite
, monazite, magnetite, and fluorite.
These Prospects exhibit REE mineralization consisting of allanite
, zircon and fergusonite, associated with felsic volcanic rocks in a mafic-felsic bi-modal volcanic belt.
