Pore-water samples were obtained from the shallow-water part of Solar Lake (Sinai) where luxurious cyanobacterial mats grow. These samples were analyzed for Ca/sup 2 +/, Mg/sup 2 +/, Sr/sup 2 +/, Cl/sup -/, SO/sub 4//sup 2 -/, and titration alkalinity (TA) to determine the role of cyanobacterial growth and degradation on the calcification of the mats. The data are modeled thermodynamically to predict mineral-pore-water equilibria. The data support earlier bacterial and sedimentological studies suggesting that the degradation of the cyanobacterial mat via sulfate reduction is of major importance in the calcification process. 34 references, 1 figure, 2 tables.
