Very interesting combo specimen with Metatyuyamunite crystals gathered together in sheafs up to 3 mm associated with very small Carnotite flakes. The Carnotite is of a paler yellow than the Metatyuyamunite and not well crystallised. The minerals sitting on a bed of Malachite. The Malachite sits in turn on Heterogenite covering Quartz crystals. Carnotite and Metatyuyamunite were rare minerals at Mashamba and the specimens where recovered in the mid 80s. Fantastic under the scope! As the Mashamba mine is flooded and most probably exhausted, no specimens will perhaps never reach the market again.
