Rameauite is a hydrated complex uranyl oxide mineral with formula K2Ca(UO2)6OH16·H2O or K2CaU6+6O20·9H2O. ==Crystallography== Rameauite has four observed forms which are {010}, {100}, {001} and {110}. The angles between these faces are {100}^{001} = 58°40` and {010}^{110} = 49° 50`. The crystals are always twinned on {100} and they are flatt.....
