Variation of sea level is in blue and that of water budget in black. The resulting simulation of
evaporite thickness is in purple. Solid and dashed lines are constrained by the initial position
of the paleoshoreline just before step 2-III, respectively at 600 m and 900 m below the present
sea level (Bache et al., 2012). The geometry of the basins is identical to that previously used
by (Meijer and Krijgsman, 2005). Evaporites begin to precipitate when water salinity reaches
130g/l (Gargani et al., 2008; Meijer and Krijgsman, 2005). The water budget is calculated
using river and Atlantic Ocean flow as well as precipitation and evaporation (Gargani and
Rigollet, 2007). See the supplementary materials for further details.
