...Esper S. Larsen Abstract The available descriptions of uranothallite and liebigite indicate them to be very similar, except in chemical composition. Three fairly satisfactory analyses of uranothallite are available and the composition must be near 2CaO.UO 3 .3CO 2 .10H 2 O. The only published...

... and schoepite. Uranyl tricarbonate minerals such as liebigite precipitate on calcite only in more highly concentrated basic solutions. The crystal morphologies of almost all of these minerals were recorded on the calcite surface with an atomic force microscope (AFM). Red crystals of becquerelite grown in acidic...

... are briefly considered. Of them, liebigite (= uranothallite) and schroeckingerite are well established. Voglite is almost certainly valid; randite certainly, and rutherfordine probably, are to be discredited; sharpite may be valid; the status of studtite and diderichite is very doubtful. * Published...
