Additionally, it contains Anthoinite AlWO3(OH)3, a mineral that is essentially the dehydrated form of Mpororoite, and this has been recorded only 15 times. Both minerals occur as a "white" powdery mixture.
This specimen was collected in 1980 and studied. A treatise appeared in the Mineralogical Magazine (September 1984, Vol. 48, PP 397-400, written by Satoshi Matsubara, Akira Kato (National Science Museum, Tokyo, Japan) and Kozo Nagashima (University of Tsubuka, Ibaraki, Japan)) about this extremely rare find. Now you can own it. It is one of the finest specimens around. You have to go to the Smithsonian to find a specimen like this one.
