...Clifford Frondel; Robert Meyrowitz Abstract Rutherfordine, diderichite, and a synthetic uranyl carbonate obtained by heating UO 3 in H 2 O under 15,000 psi CO 2 at 300° C. afforded identical x -ray powder patterns, and on analysis each yielded the formula (UO 2 )(CO 3 ). The name rutherfordine has...

... to silicates. Other specimens show clarkeite as the core, or an intermediate zone of clarkeite may form between the central uraninite and the orange-red zone of hydrated oxides. The uranyl carbonate rutherfordine has been observed as the outermost zone in some specimens, usually more or less admixed...

... 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...
