Locality: White Canyon No.1, Deer Flat, White Canyon, White Canyon District, San Juan Co., Utah, USA Dimensions: 4.9 cm x 2.3 cm x 1.4 cm Voglite and liebigite are rare secondary uranium minerals. Voglite is very rare and forms from the alteration of uraninite. This colorful, rich specimen features bright grass green voglite crystals attractively covering crusts of yellow liebigite on a sliver of coarse sandstone matrix. Ex. John White Collection of Seattle and acquired in October, 1968, according to his faded label. Mineral

Volborthite Locality: Monument No. 1 Mine, Monument No. 1 channel, Mystery Valley, Monument Valley, Navajo Indian Reservation, Navajo County, Arizona, USA Size: 7.6 x 5.7 x 3.0 cm A classic example of Volborthite from the Monument No. 1 Mine in Arizona. This mine is best known for its Volborthite specimens which have a characteristic electric yellow-green color, and platy, sometimes "rosette"-like crystal formations. Typically species with this kind of color can attribute it to the presence of Uranium, but that is not the case with Volborthite. This piece has a fair amount of crystals which are associated with pale blue Chrysocolla and minor black "specks" of what could be Montroseite or Roscoelite(?). A good representative specimen of this uncommon hydrated copper hydroxyl vanadate. Mineral

Volkonskoite-replaced fossil wood from the Permian of Russia. (4.3 cm across at its widest) This is a very rare specimen of fossil wood from Permian rocks in western Russia. Most fossil wood is preserved by quartz-permineralization or carbonization. This fossil wood has been replaced by a rare chromian smectite clay mineral called volkonskoite (Ca0.3(Cr,Mg,Fe)2(Si,Al)4O10 (OH)2⋅4H2O - hydrous calcium chromium magnesium iron hydroxy-aluminosilicate). The chromium (Cr) content gives the fossil its green coloration. The striations appear to be remnants of the original wood structure. The broken sides show that the massive, fine-grained volkonskoite breaks with a conchoidal fracture. Host rocks & age: soft fluvial sandstones, Kazanian to Tatarian Stages, upper Upper Permian Locality: Mt. Efimiatsk (Mt. Efimyatskaya), near the town of Efimyata, ~10 miles west of Votinsk Reservoir & ~30 miles southwest of Okhansk, Chastinsky District, southwestern Perm Region, western foothills of the southwestern Ural Mountains, western Russia Mineral

:Locality: Vasin-Myl'k Mountain, Kola, Russian Federation Size: 1.8 × 1.3 × 0.2 cm Description: Polished preparation of a sample with this rare species, a Rb-analogue of lepidolite. Voloshinite was found in rare-element granitic pegmatites at Mt. Vasin-Myl’k, in Kola Peninsula. It is closely associated with pollucite and lepidolite, trilithiolite, also typically with muscovite, albite and quartz; in some cases, associated minerals are K,Rb-feldspar, rubicline, spodumene, montebrasite, elbaite, etc. From the Type Locality.

(a) Polished sample with gehlenite–andradite–pseudowollastonite paralava in hornfels. Hornfels––the dark part represents weakly altered gehlenite–flamite rock, the light part altered hornfels in which flamite is replaced by silicocarnotite and Ca-hydroxides, and gehlenite by hydrogarnet. In the paralava, the minerals are coloured as follows: Ti-bearing andradite––dark brown, gehlenite––light brown, wollastonite, flamite and pseudowollastonite––white. (b) A polished thin-section from the central part of the sample is shown in Figure 1a. (c) Silicocarnotite forms single crystals and rims on fluorapatite crystals. A crystal of V-bearing silicocarnotite is marked in the lower part of the image. (d) U-bearing pseudowollastonite, vorlanite and aradite aggregate in a large pseudowollastonite grain. (e) Reaction zone of rankinite between flamite and pseudowollastonite. Ara = aradite, Adr = andradite, Fmt = flamite, Fap = fluorapatite HSi = Ca-hydrosilicate, Gh = gehlenite, Jcb = jacobsite, Pwo = pseudowollastonite, Rnk = rankinite, Scnt = silicocarnotite, Vrl = vorlanite.
