Sabkha definition

A flat area, typically lying between a desert and an ocean or salt lake, whose surface is characterized by efflorescences of salt, gypsum, and calcium carbonate as well as windblown sediments and often tidal deposits.

A flat area between a desert and an ocean, characterized by a crusty surface consisting of evaporite deposits (including salt, gypsum, and calcium carbonate), windblown sediments, and tidal deposits. Sabkhas form primarily through the evaporation of sea water that seeps upward from a shallow water table and through the drying of windblown sea spray.
