SUMMARY:Mineral and Glass Surface Reactivity: the Good\, the Bad\, and the
  Ugly - Roy Wogelius\, Manchester

DESCRIPTION:Reactions at the solid-fluid interface control a range of low-
 temperature geochemical processes\, including contaminant adsorption\, nut
 rient release\, dissolution\, and precipitation. Understanding the details
  of mineral and glass surface chemistry during reaction is complicated by 
 the presence of the aqueous fluid and by the low number of atoms present i
 n the reactive surface volume. Several surface sensitive spectroscopic tec
 hniques have been developed (e.g. X-ray reflectivity\, polarization depend
 ent EXAFS\, MIR-FTIR) in order to study such systems during reaction. Here
 \, recent work with x-ray and infra-red spectroscopic methods will be pres
 ented\, covering several natural and applied case studies with a range of 
 substrates and solutes.
