The “dolomite problem” is a geological challenge that has endured since its first iden- tification by the French scientist Deodate Do- lomieu in 1791. Our UW team has studied the dolomite for nine years with support from the NASA Astrobiology Institute, National Sci- ence Foundation, and our university. There have been three PhD students, two Master's students, and two research scientists involved in the project. Figure 1: Polyhedral models of dolomite (left) and “d dolomite” (center) projected along Ideal or stoichiometric dolomite mineral their b-axes.

Our results also show that dissolved sulfate promotes dolomite formation in the presence of the catalysts, polysaccharides or hydro- gen sulfide, at low temperature. Gypsum in dolostones indicates water with high Mg:Ca ratio and active microbial activity in presence of organic matter.
