Uranyl Adsorption onto Hydrous Ferric Oxide—A Re-Evaluation for the Diffuse Layer Model Database
Environmental Science & Technology2009-11-09
The diffuse layer model (DLM) database of Dzombak and Morel was developed to quantify the adsorption of dissolved species onto the hydrous ferric oxide (HFO) surface, and contained numerous surface complexation reactions, including surface complexation reactions for uranyl (UO2+2) consisting of Hfo_sOUO2+ and Hfo_wOUO2+.
Analysis of a monsoon flood event in an ephemeral tributary and its downstream hydrologic effects
Water Resources Research2006-03-07
Our major objective in this study is to quantify the meteorological characteristics, watershed runoff response, and surface-groundwater interactions arising from a summer monsoon flood event in the Río Puerco and its downstream hydrologic effects in the Río Grande.
Evidence for magmatic vapor deposition of anhydrite prior to the 1991 climactic eruption of Mount Pinatubo, Philippines
American Mineralogist2002-08-01
Anhydrite (CaSO4) phenocrysts from Mount Pinatubo pumices show evidence of having responded dynamically to changing conditions prior to the June 15, 1991 climactic eruption. Micrometer-sized and smaller pyramidal surface growth features and lesser numbers of etch pits on anhydrite surfaces are documented by scanning electron microscopy. Chemical analyses indicate that the pyramids are a CaSO4 polymorph and electron backscatter diffraction patterns show conclusively that the pyramids are indeed orthorhombic anhydrite and not another Ca-sulfate phase. Unit-cell measurements of volcanic anhydrite are identical with evaporitic anhydrite, as determined from single-crystal X-ray diffraction patterns.
