Todorokite Locality: Kent, Kazakhstan Size: miniature, 4.7 x 3.9 x 2.4 cm Todorokite An unusual, organic-looking , stalactiticgrowth of this complex manganese oxide which has the kitchen sink thrown into its chemistry. It is likely that this is the same locality reported on mindat as Ushkatan, mis-transliterated. In any case,a very good example of this complex oxide. Mineral

Wulfenite, Kasolite, Torbernite, Guilleminite, Malachite Locality: Musonoi Mine, Kolwezi, Western area, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre) (Locality at mindat.org) Size: 5.0 x 4.4 x 4.1 cm. This is a great combination piece containing 5 minerals. The most surprisingly spectacular are the blood red Wulfenite crystals in a prismatic habit, up to 1 mm in size sitting on a carpet of green velvet Malachite. Wulfenite is rare in Katanga (only 2 valid localities for this huge province) and in Musonoi they are at their best. They are associated with well terminated and bright yellow Kasolite crystals reaching 2 mm in size. Some are showing phantom growth. Also present are green, transparent platy Torbernite crystals reaching 4 mm on edge. The edges of the Torbernite are worth a closer look - some of them are the matrix for very small Guilleminite crystal clusters. This specimen was recovered during the removal of the U-dump in the early 1990’s. Musonoi has ceased producing minerals since then. Musonoi is the Type Locality for Guilleminite. Nothing has come out of Katanga for more than 15 years, except for Malachite and Chrysocolla. Mineral

White crystal group of the intermediate member torreyite-lawsonbauerite from the type and only known locality worldwide in Franklin (Sterling Mine, Ogdensburg, Sussex County, New Jersey, United States of America), in an analyzed specimen by SEM/EDS (Mg was detected but not quantified, small peak at 1,2). Percentages of chemical elements in the analysis are only approximate since the sample was not carbon coated to avoid soiling of the specimen. After the analysis we can see the sample is closer to the end member lawsonbauerite rather than torreyite. Eventhough, the sample was originally labeled as only torreyite, so I assume other points in the sample not detected are more Mg rich. Ex Vandenbroucke Museum collection from Waregem, Belgium.
