Improving Mindat.orgvyuntspakhkite-(Y) type locality

7th Jan 2008 19:43 UTCPavel Kartashov Manager

Vyuntspakhkite-(Y) was discovered on Ploskaya Mt. as inclusions in yttrofluorite from amazonite pegmatites. It was named according to highest mount in the region - Mt. Vyuntspakhk - very famous by its fergusonites and yttrobrytholites. But it wasn't found on this mountain at all.

Unfortunately, the descriptive paper indicates the mineral was named for the type locality. The CTMS also lists Vyuntspakhk Mt as the type locality.

For ref. see;

A.V. Voloshin, Ya.A. Pakhomovskii (1986) Minerals and mineralformation evolution in amazonite pegmatites of Kola peninsula, - Leningrad, Nauka, pp.168 (in Rus.)

or

I.V.Pekov (1998) Minerals first discovered on the territory of the Former Soviet Union, - Moscow, Ocean Pictures, p.235.

Amazonite pegmatites are absent on Vyuntspakhk Mt. Name of the discriptive paper directly show amazonite pegmatites.

By the way, it is the reason, why Igor wrote his books - to collect together type localities, which are very often omitted in original descriptions.

Fixed.

Pavel: are there refs. for the minerals you mentioned from Vyuntspakhk Mt.?

Right now, we don't have any minerals listed from there (http://www.mindat.org/loc-13725.html).

Pavel,

Obviously, I have no problem with getting the correct type locality information, but seeing it given with no reference, does bother me.

Thanks for including it.

Unfortunately in old books (Soviet times published) exact locality information for rare metal minerals always was restricted. Mostly gobal geographical terms were used - formanite from Siberia, holtite from North-West of USSR, gadolinite from Far East etc.

May be something are present in Dr. Semenov last green book, I'll see tomorrow in my lab.

I had made some changes on locality pages in Keivy section.

And now two photo are wrongly in Keivy Mountains photogallery http://www.mindat.org/gallery.php?loc=2669

Photo http://www.mindat.org/photo-24744.html bismuth/plumbomicrolite should be moved to Ploskaya Mt. page http://www.mindat.org/loc-2670.html

Photo http://www.mindat.org/photo-92546.html kyanite isn't Kola specimen at all. This specimen is from Karelia - Khit Ostrov locality http://www.mindat.org/loc-4436.html

Matrix biotitite-almandine-anortite rock and kyanite crystal appearance both are very typical for the locality. Kyanites from Keivy usually more weak coloured and grow in muscovite rock without garnet and visible feldspars. Biotite associate in Keivy with chloritoid, corundum, andalusite or chiastolite, and almost newer with primary kyanite.
