Discuss the silled (barred) basin model for evaporite deposition. What features of evaporites
does this model explain? What will be an ideal response?
The silled basin model for evaporite deposition provides a mechanism by which thick
accumulations of evaporites can be formed. The model is illustrated in Fig. 10.12 of the
textbook. Inflow of seawater continually replenishes the seawater in the basin and evaporation
causes supersaturated brine solutions to continually deposit evaporites, including salt.
