LocalitiesKarnasurt Mine

9th Mar 2016 17:23 UTCPeter Tarassoff Expert

In the locality list for the Lovozero Massif there is no mention of the Karnasurt mine/Karnasurt underground mine. Pekov (2000) places the Yubileinaya pegmatite in this underground mine. Interestingly, the mine extends from Karnasurt Mountain to Kedykverpakhk Mountain, and mineral labels can read either mountain for the mine. Pekov (2000) introduces his account of the pegmatites of Kedykverpakhk Mountain as follows:"In the northeastern part of Mount Kedykverpakhk, underground workings of the operating Karnasurt mine revealed a swarm of pegmatite veins...."

Dear Peter,

practically nobody (even here in Russia) has well labeled specimens from Karnasurt underground mine with exeption of obvious samples from Yubileinaya pegmatite vein. Probably to such exeption belongs "natropal icicles" from some open adits at the Southern slope of the Mount and belonging to the underground mine. But I didn't saw new material from these accessible adits during past 20 years.

Pavel,

I have in fact seen such labels prepared by a prominent Russian mineralogist who personally collected the specimens which are not from the Yubileinaya pegmatite. Since the Karnasurt mine is referenced in Pekov (2000) monograph, it should be listed.

Peter: feel free to add the name in parentheses, as well as any info to the locality page.

Uwe,

I have just received this clarification from a leading Russian authority on the mineralogy of the Lovozero Massif:

"...the operating part of the Karnasurt mine is [now] only underground. It consists of two areas, namely the Karnasurt area (underground workings under Mt. Karnasurt) and the Kedykverpakhk area (under Mt. Kedykverpakhk). They are connected via [a] working under the Ilmayok river valley between these two mountains. The Yubileynaya pegmatite is in the Karnasurt area of the Karnasurt mine (under Mt. Karnasurt)."

Could you please amend the Lovozero Massif locality list accordingly?

Certainly, As soon as you post that Jasper photo. Othwise you could post it yourself. This is a Wiki site!

Rob,

I'm sorry, but these are two separate issues. That photo is of a specimen in the collection of the Redpath Museum, and I do not have authority to post it on Mindat.

Besides, what's more important, correcting a serious locality omission or posting a photo of jasper.

Thanks Peter. I find it surprising that the Redpath wants to hide the important mineral heritage that still remains in the collection! I'll stop bugging you about it.

I'll attribute the Karnasurt Mine information to you and this thread, but would be more comfortable if the "leading Russian authority on the mineralogy of the Lovozero Massif" who supplied the information was revealed.

I would like to ask a question. What is the traget of the mining at Karnasurt and Kedykverpakhk? I understood the the most minerals containg "interesting" elements are silicates which are very hard to smelt. Some minerals are Ce-carbonates but I assume these are too sparse to extract.

Rgds.

Loparite. ;-)

12th Mar 2016 23:09 UTCPeter Tarassoff Expert

Rob,

The authority is Dr. Igor V. Pekov. As Pavel notes, the ore mineral is indeed loparite-(Ce), a major source of niobium, tantalum, and lanthanides in Russia. Both areas of the Karnasurt mine are currently in operation. Pekov (2007) states that raslakite (eudialyte group) was "discovered in dumps of an adit at the Kedykverpakhk area of the Karnasurt underground mine" which would make it the type locality for that species.

Thanks Peter Info added.

Look changes made by me in Karnasurt-Kedykverpahk strings.

Hello,

Thank you Pavel. Yes, I overlooked Loparite when studying the mineral lists of this region.

Studying some maps of Khibiny I found only a historical molybdenite mine at the western part of the Khibiny region and there are of course the well known apatite mines at the southern part of the region. However, is there (or was there) any other mining at Khibiny and Lovozero? Besides that are there any information that in the past there were gold panning at Khibiny and Lovozero.

Best Regards

Uwe Ludwig
