Radiating aggregates of natrolite crystals. This was found in a gully around the corner at the north end of Oisgill Bay - on the map this spot is called ’An Ceannaich’. This specimen has been analysed. I went back to the same spot recently and could not find a trace of it; I think it had been buried by rockfall. My recollection is that the natrolite was formed in a vein in the back of the gully.

Naujakasite
Ilímaussaq Intrusive Complex, Narsaq, Greenland
FoV= 3 x 3 cm;
Crystal: 1.5 x 1.2 cm
NAUJAKASITE is by no means an aesthetic mineral but it is deeply exciting conceptually, let us see why:
This string begins with two pieces of Steenstrupine, a mineral found only few places and in low quantities outside the Ilímaussaq Intrusion. It has very complex structure and around 20 different elements in the full formula, many of which are rare ones.
The Naujakasite is similar in distribution, it is practically never found at all outside the Intrusion, even if inside it is locally very common, it reach to be the main component of a rock. But in opposition to Steentrupine, its formula is surprisingly simple: Na6(Fe,Mn)Al4Si8O26
Now, in case of “strange combination of weird elements” we somehow “intuitively” accept that the formation event has been a rare one with only one or very few known occurrences on Earth. Nevertheless seeing such a simple formula with few and common elements, the uniqueness of the Ilímaussaq formation is somehow even more striking.
Strongly simplified, apart from the presence of many rare elements we are talking about a magma with very low concentrations of silicium (quarz is never found in most of the area in the central parts of the Intrusion!) and very high concentrations of sodium (Na) – an element present in high amounts in many Ilímaussaq minerals. (no wonder Sodalite has its type locality here…) (Author: kakov)

A strange mineral that formed instead of nepheline in certain parts of the hyper-agpaitic magma (=low silica, high sodium) of the Ilímaussaq Intrusion. In spite of not containing any rare elements, it is practically not found anywhere else on Earth.

Nearly 5 cm long wires of so-called "Schlotsilber" (chimney silver) from Schlema mining district, Erzgebirge, Saxony. Not all dubious silver samples without matrix are manmade in a narrower sense. Some of them have been found when the chimneys of the smelters (f.e. at Freiberg and Schlema-Schneeberg district, Erzgebirge, Saxony) got pulled down. The silver sublimated on the inside of the chimneys. It is told that big chimney fragments fully overgrown by large silver wires have been found... But there´s nothing about ever been published and actually I never saw such "matrix chimney silver". Moreover you don´t see such loose wires that often; characteristic is their luster - the shown sample is, I think, 50 years old and there is no black tarnish on. (Author: Andreas Gerstenberg)

NEPTUNITE, Pyrochlore, Tugtupite
Ilímaussaq Intrusive Complex, Narsaq, Greenland
FoV: 4 x 5 cm (for reference you have the curvature of my finger on the top)
section of Neptunite crystal in right down corner: 3 x 3 mm
I have taken this piece for the relatively well developed Neptunite crystals (NB! this is not a micro photo), the Pyrochlore is more visible in the previous piece, here there are only small spots of it to the right of the central Neptunite area. The Tugtupite is also of very bad quality.
NEPTUNITE is a relatively common mineral in some rocks of the Ilímaussaq complex, among them the beryllium bearing hydrothermal veins. Hence if you have Tugtupite in your collection on a relatively decent sized matrix, it is highly probable you also will have Nepunite in it somewhere.
We are not talking about showy crystals like the well known wonders from San Benito, California, the grains/crystals here seldom get over a few mm and they are usually surrounded by other minerals. Nevertheless the Ilímaussaq Neptunite has some really interesting features, of which I would highlight:
1) It always shows the deep red colour.
2) Association: in the Tugtupite bearing hydrothermal veins the Neptunite grains are almost always directly associated with the niobium mineral Pyrochlore, that forms yellow or light brown irregular spots or oblong areas with a greasy lustre. Inside or near this substance we have dark grains, clearly deep red with a 10x loupe and often of romoidal shape – this is the Neptunite!
3) Cultural aspects: Although the type locality is not Ilímaussaq rather the Narsarsuk pegmatite located in the Igaliko intrusive complex, the two locations are relatively close to each other (and type locality Neptunite is practically impossible to get!). Furthermore we can say that the name given to the mineral is somehow equally justified at this site: In the Narsarsuk pegmatite there are big amounts of Aegirine, named after the sea god Aegir in the Nordic mythology – this association inspired the usage of “Neptun”, the Roman sea god in the nomenclature of the associated mineral. And well, Aegirine is also a common mineral in the Ilímaussaq complex… (Author: kakov)
