Fars province

The Zagros fold-and-thrust belt in the Fars province (Iran). 2. Thermal evolution

Temperature-dependent clay minerals and vitrinite reflectance data, surface and subsurface geological constraints were used to unravel the burial evolution of the Ordovician-Quaternary sedimentary successions from the inner to the outer zones of the Zagros fold-and-thrust belt in the Fars province (Iran). These sedimentary successions were buried to their thermal maxima during early to late diagenesis, achieving temperatures corresponding to the immature to early mature stages of hydrocarbon generation.

Zagros fold and thrust belt in the Fars province (Iran) I. Control of thickness/rheology of sediments and pre-thrusting tectonics on structural style and shortening

The 300 km long arc of the Fars province is located to the south east of the NW-SE trending and SW vergent
orogen of the Zagros Mountains. This region is one of the largest hydrocarbon reserves worldwide, and also as a
territory of high quality outcrops. Geological cross-sections of the Zagros belt are usually based on very large
scale geological maps (1:1.000.000 or 1:250.000), and on few subsurface data and aim at describing the decoupling
relationship between cover and basement rocks and the subduction/collision history of the Arabian –
Eurasia plates.
