Uranium sorption experiments were carried out at ∼25 °C using natural samples of the lichen Peltigera membranacea. Thalli were incubated in solutions containing 100 ppm U for up to 24 h at pH values from 2 to 10. Equilibrium sorption was not observed...

Role for lichen melanins in uranium remediation (1998)
Journal Article

Lichens are successful colonizers in extreme terrestrial habitats world-wide, including metalliferous environments1. Their ability to accumulate metals has led to their use in monitoring radionuclide fall-out from Chernobyl and uranium uptake from du...

Uranium is enriched in depleted island arc magmas more than would be anticipated, due to the overall enrichment in large ion lithophile elements. To attempt to understand this enrichment calculations were performed to establish concentrations of uran... Read More about Uranium and thorium solubilities in subduction zone fluids.

Determination of uranium and thorium in basalts and uranium in aqueous solution by inductively coupled plasma mass spectrometry (1993)
Journal Article

Methods are described for the simultaneous determination of uranium and thorium in basaltic rocks at concentrations from mg kg-1 (ppm) to ?g kg-1 (ppb) levels and for uranium in solution at femtogram levels. The technique for basalts does not require... Read More about Determination of uranium and thorium in basalts and uranium in aqueous solution by inductively coupled plasma mass spectrometry.
