Summary:

The Khemisset Basin is a sedimentary basin of Triassic age, initiated by the opening of the mid-Atlantic ridge. The sedimentary sequence of the basin is characterised by early continental red bed deposits including iron-rich sandstones. Continued subsidence and extensional faulting in the late Triassic and early Jurassic resulted in the deposition of clay and extensive evaporite sequences, characteristic of a closed marine basin and thought to exceed 1,000m in thickness in some areas. The evaporitic sequence is primarily comprised of halite, gypsum and locally, sylvite and carnallite.

The Khemisset basin was characterised by a continental slope leading into a shallow marine environment with the deposition of carbonate banks and the formation of a carbonate platform with associated dolostone and dolomitic limestone deposits. Around this time Western Morocco also experienced the deposition of extrusive basalts. Subsidence in the Moroccan continental margin continued into the Middle Cretaceous, until a period of uplift in the Late Cretaceous leading to salt diapirism; the intrusion of salt into surrounding host rock to form domes. As the rate of subsidence slowed, the basin became erosive leading to the deposition of a thick Tertiary sedimentary sequence of marls and conglomerates.

The evaporite sequence is equivalent to the Lower Salt Formation observed within the Khemisset basin and represents a regional target for potash exploration.
