C7U-169Gedrite : ◻Mg2(Mg3Al2)(Si6Al2)O22(OH)2

Skisshyttan, Smedjebacken, Dalarna, Sweden

Dimensions: 130 mm x 70 mm x 30 mm
Field of View: 140 mm
Weight: 285 g

Gedrite from Schisshyttan, Ludvika

Weight: 285

Large sprays of gedrite in a pale rock.

This one I spent 20 minutes just hitting the same spot on the solid bedrock with my 5 kilo sledgehammer. When I finally heard a crack I stopped and put a chisel in. When I turned the piece over in my hands this was what I was greeted by.

1R6-7HQFluorite : CaF2, Feldspar Group, Quartz : SiO2

Åkerlandet, Dorotea, Lappland, Sweden

Dimensions: 70 mm x 45 mm x 25 mm
Field of View: 85 mm
Weight: 82 g

Fluorite crystals from Åkerlandet

Weight: 82g

Nice pale blue crystals of fluorite is scattered over the surface of this rock. The fluorites are accompanied by tiny clear quartz crystals and white to clear feldspar crystals, probably albite.

There is a fine crack across the stone.

The rock is made up of gneiss or granite with quartz, feldspar, mica and garnet. One side is from an open fracture and there is where the fluorite crystals have grown.

The fluorites have a clear blue fluorescent in both short and long wave UV light.

AE4-K7HSmithsonite : ZnCO3, Fluorite : CaF2, Sphalerite : ZnS, Calcite : CaCO3

Åkerlandet, Dorotea, Lappland, Sweden

Dimensions: 60 mm x 35 mm x 25 mm
Field of View: 60 mm
Weight: 47 g

Smithsonite and fluorite from Åkerlandet, Lappland

Weight: 47g

Yellow rounded grains of smithsonite in a cavity with pale green fluorite crystals.

The rock is made up of brecciated mudstone with the fractures filled up with white calcite, brown sphalerite, pale green-blue fluorite. The smithsonite seems to be a later alteration as it only sits in or near open cavities and fractures.

The smithsonite is greenish yellow fluorescent in both short and long wave UV light. With the clear blue fluorescent fluorite this is a very nice specimen in UV.

Smithsonite is not that rare in this locality but this is the only cavity I have found. I didn't collect this specimen on site but in materials a friend discarded. Since then I have visited the mine several times and found smithsonite every time but never anything close to this specimen.

Tested with EDS and SEM.

2X8-N0EUraninite : UO2, Feldspar Group, Biotite

Multiple photos available
Ingelsbo pegmatite, Båraryd, Gislaved, Småland, Sweden

Dimensions: 50 mm x 25 mm x 20 mm
Field of View: 45 mm
Largest Crystal Size: 10 mm
Weight: 27 g

Uraninite crystals in feldspar from Ingelsbo

Weight: 27g

At least 5 crystals from 10 mm cube down to 3 mm sits on a piece of biotite and then encased in feldspar.

Looking from the side we can see a 10 mm cube to the left with a 3 mm attached, then two almost parallel cubes that have grown together. Towards the narrow end there is another cube on it's side. At the back there are three more crystals but not as easily seen as that surface is an old iron stained fracture.
The cubes are covered in a thin crust of unknown composition that shows weak greenish fluorescence, so it probably contains secondary uranium minerals.

4HD-0ATBoulangerite : Pb5Sb4S11, Galena : PbS

Sala Silver Mine, Sala, Västmanland, Sweden

Dimensions: 65 mm x 60 mm x 30 mm
Field of View: 70 mm
Weight: 340 g

Boulangerite in galena from Sala Silvergruva

The middle part of this rock is covered with a patch of gray metallic boulangerite. To the right is pure coarse massive galena, the red spots are just reflections of a brick house nearby.
The grayish green mineral that makes up most of this rock is diopside with patches of galena.

WXU-FDPHellandite-(Y) : (Ca,REE)4Y2Al◻2(B4Si4O22) (OH)2

Lindvikskollen quarry, Lindvikskollen-Kalstadgangen pegmatite, Kragerø, Telemark, Norway

Dimensions: 50 mm x 40 mm x 30 mm
Field of View: 55 mm
Largest Crystal Size: 15 mm
Weight: 64 g

Hellandite-(Y) in quartz

Collected a beautiful day on a field trip with Västerås Amatörgeologiska Sällskap.

Several crystal surfaces visible with some damages on edges.
Breaking up this quartz rock revealed what seems to be several inter grown crystals. I'm itching to expose more of the crystal by trimming off some of the quartz. If I do I will update with more pictures.
