Dr. Parkhurst: I am doing masters research (with Heather Jamieson at Queen's University) on mineral-water interactions in diamond mine waste in Canada's north. I want to carry out reaction path modeling with PHREEQC, but I am having some trouble using the REACTION keyword data block. The main mineralogy of my waste rock is: chrysotile (~ 50 %) forsterite (~40%) calcite (~7%) gypsum (~ 3%) The trouble I am having is figuring out how to enter the relative stoichiometry of these minerals based on the modal abundances I have listed above. Would you be able to give me some hints on how I should approach this conversion? Thank you in advance for your help.
