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.

Type locality specimen. The Parnauite is less than 1mm in size but is clustered in 6x5mm vug. The Parnauite forms equant to tabular crystals resembling the edges of pages of a book. They are glassy and translucent along the edges. It is probably one of the rarer minerals at Majuba. On the far end is Chalcophyllite - hexagonal thin bluish green plates.

Perhamite is found at the hot pink arrows and look like sugary ball-like masses which glitter from carbonate apatite. At the blue arrows are balls of light blue cuprian Morinite. The red arrows show a grass green Kidwellite, the yellow arrows show Chlorargyrite, and the green arrow are bubbly Dufrenite. There's a lot of species on the specimen and you should have fun with this. The two photos show Lipscombite.
