Fig.4a Average annual rate of evaporation predicted by the PFM initialized for gypsum (initial salinity = 175) minus the average annual rate of total atmospheric precipitation (E-P)
calculated by GENESIS (2.0). The contours range from 0 to 8 mm-day, e.g. only positive values of E-P are shown. The most positive values of E-P are over regions with the greatest potential for gypsum deposition. The compiled evaporites are shown as in Fig. 1A.
b PFM prediction of modern evaporites for the Northern Hemisphere summer (June, July,
August).
c PFM prediction of modern evaporites for the Southern Hemisphere summer (December,
January, February)
