Uranium and potassium are easily leached from tuffaceous rocks, although thorium is not. Transport efficiency is higher for potassium than uranium. Uranium is immobilized by reduction or complexing. Potassium tends to be more thoroughly flushed, although it may be retained on clays and stabilized during diagenesis. Uranium and potassium tend to be separated during uranium precipitation. Organic-rich shales and uraniferous sandstones can be identified. Uranium-thorium-potassium contents determined by chemical analysis will differ from values obtained by gamma-ray spectroscopy, but these differences are informative with respect to the timing of geochemical mobility.
