Hydrothermal Phase Relations Among Uranyl Minerals at the Nopal I Analog Site
Published online by Cambridge University Press: 19 October 2011
Abstract
Uranyl mineral paragenesis at Nopal I is an analog of spent fuel alteration at Yucca Mountain. Petrographic studies suggest a variety of possible hydrothermal conditions for uranium mineralization at Nopal I. Calculated equilibrium phase relations among uranyl minerals show uranophane stability over a broad range of realistic conditions and indicate that uranyl mineral variety is a consequence of chemical potential heterogeneity.
