The structural style of the southeastern region of the Dezful Embayment (Zagros fold-and-thrust belt) was defined through the interpretation of satellite images, field surveys, well stratigraphy, and magnetotelluric and seismic profiles. The compressional setting of the area derives from the last phases of Cenozoic continental collision between the Arabian Plate and Eurasia. The shortening affected an ∼13 km thick sedimentary succession comprising Proterozoic units (Hormuz Formation?), Cambrian to Early Miocene platform sediments (mainly carbonates), the Gachsaran evaporites, and Mio-Pliocene foredeep clastic deposits.

Although in the Dezful Embayment there is no evidence for outcropping Hormuz salt, the structural features of the...
