The research addresses the effects of fluorine on alkali                        diffusion in alkali feldspar.  It is expected that fluorine will                substitute readily for oxygen in the feldspar structure                         disrupting the silicate framework and introducing vacancies in                  the cation istes, and will thereby increase the rate of alkali                  diffusion. Alkali diffusion will be studied over a temperature                  range of about 500-1000oC and pressures from 1 bar to 15                        kilobars.  Early experiments will be anhydrous, but water will be               added later to check the combined effects of the two volatiles.                 Results will be analyzed by either electron microprobe or                       transmission electron microscopy, as appropriate, to determine                  the alkali diffusion rates.  The isolated effects of                            temperature, pressure, and fluorine fugacity will be measured.                  The results will be applied to determination of the time required               for specific geologic events to take place.
