Description

Mundite occurs at Kobokobo, Kivu, Zaire, as yellow tablets flattened with 3 perfect cleavages. The crystal lattice is orthorhombic and the density is 4.295. The X-ray powder was determined. The crystals are optically biaxial negative. Formula is Al(UO2)3(PO4)2(OH)3 approximately 5.5H2O. Mundite belongs to the structural group of phosphuranylite

Abstract (French)

La mundite provient du gisement de Kobokobo, Kiwu, Zaire sous forme de plaquettes jaunes aplaties avec 3 clivages prononces. Son systeme cristallin est orthorhombique et sa densite est 4,295. Le spectre de poudre a ete determine. Le mineral est biaxe negatif. La formule chimique est Al(UO2)3(PO4)2(OH)3 approximativement 5,5H2O et son groupe structural est celui de la phosphuranylite
