   The Shotur Kuh complex, exposed in the NE part of the Great Kavir block, is composed of amphibolite facies metaigneous rocks and micaschist, and of lower-grade Permian-Miocene cover sequences that experienced four main deformation phases and at least two metamorphic events. The D1 deformation phase is associated with a prograde metamorphism that in the basement reached amphibolite facies conditions. The D2 event corresponds to post-collisional exhumational upflow of middle crust. The D1 and D2 events are considered as Mid-Cimmerian. The D3 folding event is characterised by NE-SW shortening. Considering the Late Cretaceous age of this deformation, it is related to the late Cimmerian-Early Alpine orogeny. The D4 folding event is characterised by NW-SE shortening. This deformation event is associated with Late Cenozoic convergence between Arabia and Eurasia, and it could be combined with a left-lateral activity along the Great Kavir fault-bounding system.
