The NE-trending Mahallat, Muteh and Laybid complexes in the middle part of the NW-trending SSZ are the exception and have a trend almost normal to the NW-trending Zagros. SSZ is formed as a result of the Arabia-Eurasia collision and its general trend of deformation coincides with the NW structural trend of the collision. Sanandaj-Sirjan zone (SSZ), known as the metamorphic belt of the Zagros orogeny, marks the SW margin of the Central Iran. Three major inherited pre-collisional NW-, N- and NE-trending basement discontinuities have played important roles on the structural and tectono-sedimentary evolution of the Iranian micro-continent in the northeastern part of the Gondwana super-continent. Reactivation of long-lived basement faults has significant influences on further deformation of collision zones. Reactivation versus reworking of the active continental margin during the Zagros collision: Mahallat-Muteh-Laybid complexes, Sanandaj-Sirjan zone, IranĪflaki, Mahtab Shabanian, Esmaeil Davoodi, Zeinab Mohajjel, Mohammad To balance plate circuits and documented shortening requires whole-sale subduction of ~500-800 km of continental Both a 25 and a 35 Ma collision estimate thus requires that a considerable portion of the Arabian plate subducted without recognized accretion of its upper crust. These estimates suggest that the orogen has shortened 200 to 300 km since the early Miocene. #Texture patch 2.0 by albert marin garau plus#Shortening within Eurasia is estimated to be 53-75 km through the Kopet Dagh and Alborz Mountains, plus 38 km across Central Iran. Balanced cross-sections give 105-180 km of Zagros shortening (including estimates from the Zagros proper, 45-90 km, and the Zagros "crush" zone, 60-90 km). The Zagros fold-thrust belt consists of thrusted upper crust that was offscraped from subducted Arabian continental lithosphere. To assess the consequences of these collision ages for the amount of Arabian continental subduction, we compile all documented shortening within the orogen. Plate circuits indicate, from NW to SE along the collision zone 490-650 km of post-25 Ma Arabia-Eurasia convergence and 810-1070 km since 35 Ma. Africa-North America-Eurasia plate circuit rotations, combined with Red Sea rotations provides precise estimates of the relative positions between the northern Arabian margin and the southern Eurasia margin. However, upper plate deformation, exhumation and sedimentation are used to argue for an older, 35 Ma collision age. Both lower Miocene synorgenic strata with growth structures adjacent to the main Zagros fault and upper Oligocene to lower Miocene overlap strata over post-collisional thrusts are derived from Eurasia and require that collision was underway at least by ~25-24 Ma. Estimates on the age of collision for Arabia and Eurasia range from late Cretaceous to Pliocene, based on a wide variety of presumed geologic responses. When did continents collide, and how is convergence partitioned after collision are first order questions that seem to defy consensus along the Alpine-Himalyan orogen. We argue that when both PI and Psi occur, participants will respond realistically to the virtual reality.Retrodeforming the Arabia-Eurasia collision zone : Age of collision and magnitude of continental subduction Psi is determined by the extent to which the system can produce events that directly relate to the participant, the overall credibility of the scenario being depicted in comparison with expectations. PI is constrained by the sensorimotor contingencies afforded by the virtual reality system. In the case of both PI and Psi the participant knows for sure that they are not ‘there’ and that the events are not occurring. Second, plausibility illusion (Psi) refers to the illusion that the scenario being depicted is actually occurring. The first is ‘being there’, often called ‘presence’, the qualia of having a sensation of being in a real place. The idea is put forward, based on the experience of a large number of experimental studies, that there are two orthogonal components that contribute to this realistic response. In this paper, I address the question as to why participants tend to respond realistically to situations and events portrayed within an immersive virtual reality system.
