X10-628Poyarkovite (Hg2+2)3Cl2O2

Multiple photos available
09449810015710863077405.jpg
Khaidarkan Sb-Hg deposit, Batken Region, Kyrgyzstan

Field of View: 1.2 mm

Extremely tiny grain, or crystalline aggregate, of dark red poyarkovite. This very rare, 5-locality species, chemically dimercury chloride oxide, readily darkens in light and this grain is a proof. A larger grain, shown in the child photo, is completely black (although I suppose some even more tiny unchanged remnants may reside in its interior).

6MX-HRLNechelyustovite (Ba,Sr,K)2(Na,Ti,Mn)4(Ti,Nb)2(Si2O7)2O2(O,H2O,F)2·4.5H2O

Kirovskii apatite mine, Kukisvumchorr Mt, Khibiny Massif, Murmansk Oblast, Russia

Field of View: 1.2 mm

Small beige intergrown blades of the extremely rare barium- and sodium-rich representative of the lamprophyllite group of the seidozerite supergroup - nechelyustovite. Nechelyustovite is chemically close to other group members - barytolamprophyllite, delindeite, and nabalamprophyllite. Specimen delivered by Jarek Skupniewski - thanks!

QXU-765Ammonioborite (NH4)2[B5O6(OH)4]2·H2O

Multiple photos available
00142380015710859456672.jpg
Larderello, Pomarance, Pisa Province, Tuscany, Italy

Field of View: 7 mm

Small compact mass composed mainly of ammonioborite (though likely with associated sassolite and larderellite). The somewhat botryoidal nature of this specimen may be seen in the child photo. Ammonioborite and larderellite (its dimorph) are the only currently known natural ammonium borates.

A7P-WL9Chlormagaluminite Mg4Al2(OH)12Cl2·3H2O

01954660015710854476489.jpg
Kapaevskaya Pipe, Middle Angara River, Irkutsk Oblast, Russia

Field of View: 1.2 mm

Very rare representative of the quintinite group of the hydrotalcite supergroup - orangish platy chlormagaluminite. This magnesium aluminium chloride hydroxide trihydrate is a 4-locality species. It is the chlorine (or chloride) analogue of quintinite and, at once, the only group member with chloride (and not carbonate) as a dominant anion. The true structure of the mineral was resolved only very recently.

KVN-8A2Indigirite Mg2Al2(CO3)4(OH)2·15H2O

Multiple photos available
03938280015710854475208.jpg
Sarylakh Au-Sb deposit, Indigirka River Basin, Sakha Republic, Russia

Field of View: 1.2 mm

Very small crystals - intergrown needles and plates - of the extremely rare species indigirite. Named after the rather large Indigirka river, this max-two-locality magnesium aluminium carbonate hydroxide pentadecahydrate proved to be quite difficult to picture due to some light reflections. I thus used some filtering, hence the false blue coloration of the surrounding carbon-filled tape (I've tried to remove the blue but it was insufficient). More true-colour indigirite may be seen in the child photo, though. Specimen provided by Jarek Skupniewski - thanks!

55J-XQ6Komkovite BaZr[Si3O9]·3H2O

06267650015710847315649.jpg
Vuoriyarvi alkaline-ultrabasic massif, Northern Karelia, Murmansk Oblast, Russia

Field of View: 1.2 mm

Extremely rare, single-locality light brown komkovite, as an evident crystal intergrown with some other species (possibly dolomite, baryte, or georgechaoite). This barium zirconium cyclic trisilicate is a member of the hilairite group. It is the barium analogue of both hilairite and calciohilairite. Specimen provided by Jarek Skupniewski - thanks!

LGM-PN1Labyrinthite (Na,K,Sr)35Ca12Fe3Zr6TiSi51O144(O,OH,H2O)9Cl3

Koashva Open Pit, Koashva Mt, Khibiny Massif, Murmansk Oblast, Russia

Field of View: 2.5 mm
Largest Crystal Size: 2 mm

2 mm crystalline chunk of brownish-red labyrinthite, unique Ti-bearing member of eudialyte group. This sample, obtained from Mikhail Murashko / Sergey Vasiliev (thank You!) was originally author-analyzed by means of structural XRD and chemical methods. This is a close-up.

A3M-A2MOlgite (Sr,Ba)(Na,Sr,REE)2Na(PO4)2 , Villiaumite NaF

Multiple photos available
00915200015690069263794.jpg
Palitra pegmatite, Karnasurt mine, Kedykverpakhk Mountain, Lovozersky District, Murmansk Oblast, Russia

Field of View: 8 mm

I have obtained this specimen as OLGITE. Handbook of Mineralogy reports olgite to be "bright blue or bluish green", with xls size up to 2 mm. Although olgite (possibly soon to be renamed to strontio-olgite, or maybe olgite-(Sr)) seems to be unknown from the Palitra pegmatite, so is any other blue mineral (fluorapatite included). As such, the xl of the main photo, possibly as long as 6-7 mm, would be quite exceptional for the species.
The second photo shows a grain of probable olgite, plus typical intergrown cubes of dark red villiaumite.

The last photo shows what I though could be "cleiophane" (sphalerite). However, the local sphalerite seems to rather be reddish-brown. Handbook of Mineralogy reports BARIO-OLGITE to be, exactly, light green. I think these greenish crystals could represent this species - possibly.

The vivid yellow microcrystalline mineral: manaksite???

R0J-A8ARuitenbergite Ca9B26O34(OH)24Cl4·13H2O , Sylvite KCl

Potash Corporation of Saskatchewan Mine, Penobsquis, Cardwell Parish, Kings Co., New Brunswick, Canada

Field of View: 7 mm

Red/reddish sylvine bearing inclusions of extremely rare borate - ruitenbergite. I am not sure which microcrystals or inclusions fit to ruitenbergite, but I assume they are not the greenish ones but some tiny colourless ones. However, the child photo shows the greenish part of the specimen with some tiny colourless crystals likely on a(nother?) greenish species, plus some yellow ones, which may fit (awaiting informations from the dealer).

Field of View: 2 mm

Yellow microcrystalline swartzite - very rare (4-locality) magnesium calcium uranyl carbonate hydrate) - intermixed with gypsum.
