THE MECHANICAL INTERACTION BETWEEN THE ARABIAEURASIA COLLISION AND CAUCASUS-CASPIAN SLAB-PULL IN THE NORTH WEST OF IRAN

contrasted tectonic styles occur in northern iran west of kopet dagh the south caspian basin is an aseismic and possibly rigid block involved in the collision zone between eurasia and arabia . To the NW large scale velocity field of iran given by recent GPS surveys suggests 8 mm/yr of right -lateral displacement for the WNW-ESE fault in the tabriz region
