Tiny colorless micro crystals in a vug unseen in the photos, but visible under the microscope. Pachnolite usually occurs in pegmatites with a fluorine component most notably but not limited to Ivigtut. Such pegmatites often contain fluorite, fluellite, prosopite, topaz, cryolite, ralstonite and other alkali aluminum fluoride granitic bodies which are peraluminous and usually in "NYF" (niobium-yttrium-fluoride) evolved and fractionated pegmatites. In this case Gjerdingselva is not a pematite but is alkali (soda) rich in flourine.

Glassy brown granular Pellyite throughout matrix. Pellyite is an extremley rare barium inosilicate found in only two localities outside of California, where it occurs at the Baja California and the Gun Claim in the Yukon. The Pellyite is associated with deep reddish brown short prismatic Titantaramellite, another rare barium silicate. It is shown in the last two photos.
