The break-up of Pangæa was principally facilitated by tensional plate stress acting on pre-existing suture zones. The rifting of Pangæa began during the Early Permian along the southern Tethys margin and produced the lenticular-shaped continent known as Cimmeria. A mantle-plume model is ascribed to explain the rift-related volcanism but the NW-SE oriented Cimmerian rifts do not correlate well w...

The pre-Alpine evolution of the Tethyan domains between Gondwana and Laurasia, in particular that Cimmerian continental blocks, remains poorly constrained. Central Iran is a key area to constrain closure Paleotethys collision Laurasia with blocks drifted from Gondwana. present study provides combined metamorphic geochronologic approach focused on two areas Iran: Kashmar-Kerman Tectonic Zone (KK...

The Cimmerian blocks are ribbons-like micro-continents that detached from the northern margin of Gondwana during closure Paleotethys ocean at end Permian. While it has been hypothesized slab pull forces induced by subduction beneath Eurasia could have driven extension in lower plate after mid-oceanic ridge subduction, so far, numerical modeling studies concluded these alone not sufficient to dr...

this paper presents evidence on mesozoic inversion of basin bounding faults within the taleqan-gajereh-lar paleograben (tglp) in central alborz range. for this purpose, well documented stratigraphy data across the tglp together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. the tglp has evolved through the early and mi...
