:The rare intermetallide Zhanghengite, CuZn, discovered in meteorites, become available now from an old Vietnamese collection. The mineral has nice light-yellow gold-like color and is well visible by unequipped eye. Zhanghengite is accompanied by mixture (alteration rim) of pink zincian (4.3-7.8 mas.% of Zn) native Copper, Cuprite, Hydrozincite, Smithsonite, Malachite and Cerussite. All this located mainly at the back side of the specimen. The specimen size is 1.25x0.62x0.50 mm. Chemical formula of Zhanghengite from exactly this specimen is Cu1.00(Zn0.97Fe0.03)1.00. A geological probe from unspecified "gold" deposit from Northern Vietnam was collected in the late 70th. But all gold-like metal turned out copper-zink alloy and no real gold was detected in the probe. The mineral indeed has very nice gold-like color and is very similar to native gold of AV700 fineness. Completely analyzed specimen. Mineral

Locality: Bayan Obo deposit (Bayun-Obo deposit; Baiyunebo deposit), Bayan Obo, Bayan Obo Mining District, Baotou League (Baotou Prefecture), Inner Mongolia Autonomous Region, China Dimensions: 3 cm x 2.5 cm x 1.1 cm 3.0 x 2.5 x 1.1 cm. This unique barium-cerium-carbonate-halide, a member of the bastnasite group, is in a very peculiar situation. It has an IMA/CNMMN-approved name for a non-approved mineral. The so called zhonghuacerite-(Ce) was never submitted to the IMA/CNMMN, hence it was never approved. It entered the mineralogical literature via a review in the New Minerals section of Am. Min. 67, 1078. The description was published in Chinese and reviewer was not aware that the mineral was not approved by IMA. The mineral was listed in the Glossary of Mineral Species (Fleischer 1983 and Fleisher and Mandarino 1995). Zhonghuacerite was published in 1981 without having been submitted to the CNMMN. The name was changed by the CNMMN in 1987 to zhonghuacerite-(Ce) as part of the update of mineral names with Levinson modifiers. Information courtesy MINDAT. Ex Josef Vajdak Collection. This is an extremely rich and rare example, with yellow crystals and crusts found on all sides of the sculptural wedge of matrix. Mineral

Zincite, Arizona Original description: This giant chunk of a crystal cluster is enormous. Hard to imagine the mining company being able to extract it without damaging the thousands of crystal "points". Many minerals are present here. The crystal blades are especially fascinating when they terminate from a yellow or orange to red. Mineral
