Walking on crystals…

15th Dec 2007


Zillions of crystals...


Finally got myself down to Sagåsen and Tvedalen today, been a while since last time now… The weather was nice, but cold, was about -6C when I left home. Got a little “warmer” during the day, but… Anyway it was an incredible day to be out. Literally everything was coated with ice crystals, sparkling and shining like zillions of stars. The giant bling day…


Closer look at the ice crystals


Well, after going nuts with the camera, I finally ended up in Sagåsen quarry, and could start to look for minerals that don’t disappear when brought home. It wasn’t easy to see anything, ‘cause of the ice crystal covering everything.


Ice coated pegmatite


But there was plenty of pegmatite material to look through, but not so many exciting minerals to mention. I did bring back some galena, sphalerite, molybdenite samples to check it for secondary minerals, and then it was some cancrinite... That was all. Unfortunately I forgot my hammer in the quarry, discovered this when I was back at the car, then it was just to walk back, using limited daylight…


Mjollnir after the reprimand


After getting Mjöllnir, and shooting a dozen more photos, I continued to the Saga Pearl and Almenningen quarries. Didn’t find anything there at all, but ice crystals…
They are still not doing any work in Almanningen quarry. It has been closed for more than a year now.

I walked from Almenningen to Haugane quarry, one of the quarries where nothing ever has been found. Until today…. I found a block with some pegmatite, and cavities! Natrolite crystals to a couple of cm, nothing to scream about, but the fluorapophyllite growing in between them was nice. I got out a nice miniature without a broken crystal, which is going straight into my collection. Now I’m waiting for the other things to dry up so I can have a proper look at them too. In the same block I saw some meliphanite, and everywhere beryllium is present, it’s interesting things to be found. So finally all the walking paid of…

It appears as if we do not have the Haugane Quarry listed in Mindat. Perhaps you could enter it to capture your finds?

A slightly miss spelling from me, I think... I did an change to Walter Rimstad (Hauane), and added the new minerals.

Very nice reports, Peter !
The reports from your visits to the quarries in the Langesundsfjord-area are very much appreciated by many of us who more rarely have a chance to go out and collect there. As for the naming of the quarries, there is a potential problem for the posterity as they over time change ownership and names. Sometimes a name has bee transfered from one quarry to another with the change of operations. There is a problem today to trace some of the quarries named on 20 years old labels from the area. Hopefully when Alf Olav Larsen has finished his work on the minerals and localities in the area, there will be a documented reference that can be usefull in the future.

Thank you for kind words, Knut!

The use of old names on some of the quarries, really confused, and still cunfuse me. There is still some names of quarries/quarries I have no idea where is in the Tvedalen area. But I think I have most of the still operating ones under control...

A further look through the material collected on Saturday, I've found; Hydrozincite and wulfenite (+ a "UK"), the last in a couple of samples, where one was with transparent yellow bipyramides (very small of course), from Sagåsen. Helvite, leucophanite, britholite-(Ce) and a strange blueish apatite/britholite(?) crystal inside a zircone fragment, all from Hauane. I guess I have to take a trip back to Hauane the coming Saturday too...

When will I find time to clean the house before Christmas?
