Uranium (U) is of enormous global importance because of its use in energy generation,
albeit with potential environmental legacies. While naturally occurring U is widespread in the …

The solubility of uranyl minerals controls the transport and distribution of uranium in many
oxidizing environments. Uranyl minerals form as secondary phases within uranium deposits …

The origins and near-surface distributions of the~ 250 known uranium and/or thorium
minerals elucidate principles of mineral evolution. This history can be divided into four …
