VUN-KNEActinolite : Ca2(Mg4.5-2.5Fe2+0.5-2.5)Σ=5Si8O22(OH)2, Ferriallanite-(Ce) : CaCeFe2+Fe3+Al(SiO4)(Si2O7)O(OH), Magnetite : Fe2+Fe3+2O4, Pyrite : FeS2

Ust'-Biraya, Biraya Fe-REE ore occurrence, Biraya and Bya Rivers confluence area, Vitim Plateau, Irkutskaya Oblast', Prebaikalia, Eastern-Siberian Region, Russia

Field of View: 12.5 mm

Surface of natural preparated carbonatite rock. Tabular crystals of deep marine-green Na-bearing Actinolite naturally leached by rain water from carbonate matrix. Black phase intergrown with amphibole is Ferriallanite-(Ce). Single black grains within carbonate matrix is Magnetite (some of them may to be Franklinite and needs in checking). Some brown limonitized Pyrite cubes also are visible. Surface of the outer silicate rim of the carbonatite vein contacted before with shists.

SEM image of the particle leached from carbonate rock. Medium bright in BSE platy crystal (note complex termination at its top) of Ferriperbøeite-(Ce) are penetrated by two more darker prismatic striated Ferriallanite-(Ce) crystals and intergrows with brightmost isometric crystal of Monazite-(Ce). Small bright rhomb-shaped crystal right over micrometer bar is Törnebohmite-(Ce).

7GX-UG6Iron (Var: Kamacite) : (Fe,Ni), Goethite : α-Fe3+O(OH)

Multiple photos available
Chinga (Chinge) meteorite, Chinge River, Tuva Republic, Eastern-Siberian Region, Russia

Dimensions: 5.9 cm x 3.6 cm x 2.2 cm
Weight: 104.4 g

Small individual fragment of the meteorite unearthed almost 100 years later of the first its find in 1913.
Ataxite matrix of the meteorite contains 15-16 mas.% Ni. But its plessite almost don't contains Taenite (which is very rare in the meteorite matrix), but composed by mixture of Kamacite with different Ni contents - with ~15 and ~20 mas/% Ni.

TM8-NCTQuartz : SiO2, Albite : Na(AlSi3O8)

Murunskii Massif, Chara and Tokko Rivers Confluence, Aldan Shield, Sakha Republic, Eastern-Siberian Region, Russia

Dimensions: 6.5 cm x 4 cm x 5 cm
Largest Crystal Size: 12 mm

Bipyramidal Quartz crystals encrustation on wall of open fissure in metamorphic shists very usual for Aldan shield type. For the region only one is unusual - large size of quartz crystals, normally they are much more smaller (up to 2-3 mm) in such fissures.
As whole there too dark coloration of crystals of Cumberland habit (var. Morion) is unusual. Such coloration is connected with circulation of radon along these fissures. Such dark quartz is typical for regions around uranium deposits (El'kon group, Murun e.a.). Indeed at the side surfaces of the sample unidentified yet uranium secondary mineralization was detected under UV. Other associating minerals are yellowish crystals of Albite and invisible at the photo very minor secondary green copper mineralization.
