Figure 5: SEM observation of U-containing aggregates in soil.
From: Mobile uranium(IV)-bearing colloids in a mining-impacted wetland
SEM image and SEM-EDS mapping results of an aggregate exhibiting a morphology distinct from that of surrounding clay particles in the 15–20 cm soil sample at spot A. This aggregate contained Al and Si (albeit at lower concentrations than the surrounding aluminosilicates), O, Fe, P and U. Scale bar, 2 μm
