The simulation demonstrates how capillary evaporative pumping transports saline groundwater upward through a coastal sabkha and how humidity, temperature, and water-table depth control whether gypsum or halite crusts form at the surface.
Adjust the sliders for humidity, temperature, and water-table depth to watch brine rise through the sediment profile and observe how quickly and where mineral crusts crystallize.
Sliders for humidity, temperature, and water-table depth
The classic sabkha model built from studying the modern Abu Dhabi coastline is now used by geologists worldwide to interpret gypsum and halite deposits that are hundreds of millions of years old.
