Abstract

Abstract The Tellian foreland in Algeria represents a part of the southern Tethyan margin during the Mesozoic. Its tectonic evolution includes a rifting stage during the Triassic and Liassic times characterised by tilted blocks and early diapiric events during the Liassic, a post-rift regime from Middle Jurassic up to the Late Cretaceous and basin inversion during the Tertiary related to the African and European plates convergence. The subsidence modelling supported by surface and subsurface data integration emphasises different subsidence phases. (1) Liassic subsidence phase under Tethyan and Atlantic control related to crustal thinning. (2) Late Jurassic, Cretaceous and Tertiary subsidence phases, where the first one is linked to diapiric events and the second in eastern Algeria to the effects of the rifting event developed more easterly in the Gulf of Gabès and Sirte. The last one is flexural and occurs in foreland basins during the Tertiary. Taking into account the subsidence record of each structural domain, a correlation between tectonic events and the subsidence phases can be established.
