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.
