Incorporation of Uranium into Hematite during crystallization from ferrihydrite.

In addition, under conditions where biogeochemical processes can occur, it is interesting to note that hematite is recalcitrant to microbial reduction due to its crystallinity, with only a thin surface layer of bioavailable Fe(III) present, 49 again suggesting its stability may be significant in, for example, oxic-contaminated land environments.
