This proposal describes a three year research program to study                  magnesite-dolomite equilbria in the temperature range of 100 to                 200oC. One to four month dedolomitization experiments will be run               in Na-Mg-Ca-Cl brines in which equilibrium is approached by                     magnesite precipitation, following dissolution of "ordered"                     stoichiometric dolomite.  The experimental procedure has been                   successfully tested in the seven week dedolomitization                          experiments of Stoessell et. al. (1987) in which calcite-dolomite               equilibria was approached over the same temperature range.  The                 reacted solids will be examined with X-ray diffraction                          techniques, petrographic microscopy, scanning electron                          microscopy, and by an electron microprobe.  Data from the study                 will fill in the experimental gap on dolomite-magnesite                         equilibria in the 100 to 200oC range.  The results will (1) help                resolve the location of the dolomite-magnesite equilibrium                      boundary and (2) help define the stablity field of dolomite.
