Geochemical Flow Modeling
… mineralogical features characteristic of uranium roll-fronts could be reproduced using geochemical flow modeling. Under suitable conditions, selenium and arsenic mineralization occurs during roll-front genesis and that the positions of these trace metals are located immediately upstream and …

The isotope geochemistry of uranium: Igneous petrology, ore deposits, and groundwater contamination
… uranium ores. A small-scale study of a uranium roll front deposit finds 238U/235U variation in excess of 1.0‰. In both cases, the shift in 238U/235U is attributed to the nuclear field shift effect during uranium reduction. 238U/235U analysis is then applied to a groundwater remediation setting …
