JR-12 - Kasolite and possible Masuyite (?) with Metatorbernite - $ 395 SOLD Musonoi Mine, Kolwezi, Western area, Shaba Cu belt, Shaba (Katanga), Congo (Zaïre) small cabinet, 6.6 x 3.7 x 2.1 cm
A different form of kasolite in the habit of radiating crystal aggregates; also in the presence of another, more orange-red mineral (masuyite is a likely guess although it could simply be an oddly colored second deposition of kasolite - pending analysis). Either way, a gorgeous specimen!
MD-180987 - Becquerelite, Masuyite, Fourmarierite, Uranophane - - Archived Shinkolobwe Mine (Kasolo Mine), Shinkolobwe, Central area, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre) small cabinet, 6.2 x 5.8 x 3.1 cm.
6.2 x 5.8 x 3.1 cm. This large, rich specimen has three species for which this is the type locality: Masuyite (in red spherical aggregates), Fourmarierite (dark red/umber crystals underlying the Becquerelite and embedded in the matrix), and superb, large sprays of Becquerelite with crystals to a whopping 5mm. The matrix is uraninite.
MD-201157 - Masuyite, Uraninite - - Archived Shinkolobwe Mine (Kasolo Mine), Shinkolobwe, Central area, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre) miniature, 4.9 x 3.2 x 1.9 cm.
4.9 x 3.2 x 1.9 cm. Microcrystalline and acrystalline masuyite (TYPE LOCALITY) here occurs very richly, in unusual concentration in fact, coating sharp crystals of cubic uraninite (to about 1 cm). Overall a pretty specimen, and quite significant for the locality as well. From the prominent radioactive mineral collection of Alain Caubel, of France.
MUN08RAD-05 - Masuyite on Uraninite - $ 850 SOLD Shinkolobwe Mine, Katanga, Democratic Republic of Congo (TYPE LOCALITY) miniature, 4.9 x 3.2 x 1.9 cm
Microcrystalline and acrystalline masuyite (TYPE LOCALITY) here occurs very richly, in unusual concentration in fact, coating sharp crystals of cubic uraninite (to about 1 cm). I could not explain why the normally more common uranium species uraninite is so rare from this locality which produces so many other uranium minerals but an expert told me the following: The fact that Uraninite crystals are rare in Shinkolobwe is in first place that there where very few cavities where the mineral could cristalise.Where cristallisation was possible, the ground water washed the crystals away. Uranium is one of the most mobile elements so weathering is easy.
RAD08-08 - Becquerelite with Masuyite, Fourmarierite and Uranophane - $ 2750 SOLD Shinkolobwe Mine (Kasolo Mine), Shinkolobwe, Central area, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre) (TYPE LOCALITY for 3 species) small cabinet, 6.2 x 5.8 x 3.1 cm
This large, rich specimen has THREE species for which this is the type locality: Masuyite (in red spherical aggregates), Fourmarierite (dark red/umber crystals underlaying the BQ and embedded in the matrix), and superb, large sprays of Becquerelite with crystals to a whopping 5mm . The matrix is uraninite. Many are freestanding! In person, this is a beautiful specimen worthy of a display shelf, but its also an important combinatorial piece.
