FUQ-KDVOxybismutomicrolite (Bi1.330.67)Σ2Ta2O6O

01957620015817199079919.jpg
Malkhan pegmatite field, Krasnyi Chikoy, Chitinskaya Oblast, Zabaykalsky Krai, Russia

Field of View: 1.5 mm

Intergrown very dark green crystals of oxybismutomicrolite. The photo is locally slightly bluish due to white tissue used to remove some light reflections.

Tolbachik volcano, Kamchatka Krai, Russia

Field of View: 8 mm

Another Tolbachik "crazite", vlodavetsite (pronounced "vloda-vyetsite") - calcium aluminium sulfate(VI) fluoride chloride tetrahydrate (unique combination of elements among the currently known mineral species). Vlodavetsite is currently a two-locality mineral. As with many other Tolbachik minerals, vlodavetsite is deliquescent in air, and must be kept in sealed containers. This makes the child photo somewhat blurred, but I publish it as the microcrystals may likely be seen.

07N-892Vergasovaite Cu3(SO4)(MoO4,SO4)O

08270200015806417913048.jpg
Tolbachik volcano, Kamchatka Krai, Russia

Field of View: 1.2 mm

Typically dark-olive-green, single crystal (or possibly an intergrowth) of the very rare species vergasovaite (pronounced "vyer-gasova-ite"). It is another unique-element-combination mineral from these profilic Tolbachik fumaroles, and has a typical for Tolbachik feature of containing separate oxide anions in addition to being a complex oxysalt. I am thankful to Jarek Skupniewski (Geotrader) for this specimen.

Tsumeb Mine, Tsumeb, Oshikoto Region, Namibia

Field of View: 3 mm

Intergrown colourless needles of the very unique Tsumeb species, biehlite. This unique-element-combination species (Sb-Mo-O) is also the only currently known natural antimonyl molybdate. It also seems to bear some untypical arsenyl cation.

Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Field of View: 2 mm

Tiny pseudocubic complex crystals with two chemically and structurally related, complex species: ramikite-(Y) (lithium sodium (calcium) yttrium zirconium orthophosphate carbonate oxide hydroxide (fluoride)) in their cores and peatite-(Y) (lithium sodium yttrium orthophosphate carbonate fluoride(hydroxide)) in the rims. The bottom yellowish crystal seems to bear more ramikite-(Y), as this species may be yellowish. The associates include yellow crystals of something I think is rhodochrosite-siderite solid solution, while the colourless species are most likely albite, gobbinsite, and chabazite-Na, with sabinaite possible in addition.

Streuberg Quarry, Bergen, Zobes-Bergen mining district, Vogtlandkreis, Saxony, Germany

Field of View: 1.2 mm

Nice, though tiny, sprays of yellow crystals of bergenite (calcium barium uranyl orthophosphate oxide hexadecahydrate) - a secondary uranium species representing unique combination of elements among the currently known, ~5557, mineral species. Bergenite is very rare, as it is likely known from just <10 localities worldwide.

Tiny orange microcrystals of vandendriesscheite, with unidentifield blue and pale-yellowish-beige species.

Lubin Mine, Gmina Lubin, Lubin Co., Lower Silesian Voivodeship, Poland

Field of View: 4 mm

Nice spray of colourless needles of the rare mineral rapidcreekite. It grows on dripstone-like aggregates mainly composed of monohydrocalcite-aragonite intergrowths. The blue species was initially identified, by some unknown researcher(s), as geminite - a wrong identification, as geminite and rapidcreekite partially coincide in terms of their PXRD patterns. The blue colouration of these specimens comes from (1) Cu admixture in otherwise slightly zincian and sulfatian monohydrocalcite, (2) locally rich coverage and ribbon-like thin inclusions of a CuCa(ZnNiCoMg) arsenate species that is either a variety (or possibly a carbonate analogue) of parnauite, or a new mineral species. This assemblage is characterized in a soon-to-be-submitted paper (Ł.K., Mateusz Świerk, Rafał Siuda, Eligiusz Szełęg, Beata Marciniak-Maliszewska).

Field of View: 8 mm

Another example of quartz-microcline-plagioclase sandstone covered by Cu-OH-Cl species (mainly clinoatacamite, with rather evident admixture of herbertsmithite, and possible paratacamite). Although the black dendritic mineral was initially (macroscopically) attributed to tenorite, no tenorite (or paramelaconite or delafossite) were indentified in this sample. Mateusz Świerk specimen.

A zoom of the surface of a chunk of quartz-orthoclase-microcline-plagioclase sandstone covered mainly by herbertsmithite. Possible additional species associating include wooldridgeite (or nesquehonite), and kipushite (doubtful, needs confirmation). Mateusz Świerk specimen.
