upper-mantle shear wave velocity structure of the northern zagros from teleseismic tomography and transdimensional joint inversion of long and short period seismic data

One of the youngest orogenic belts, the zagros orogeny in the northern margin of the arabian plate is formed during the arabia-eurasia collision. despite a number of studies, the lithospheric structure of the zagros and its deformation during the continental collision are less studied. we use seismic data from 44 seismic stations of zagros03, a dense temporary seismic array installed across the northern zagros and central alborz. using the adaptive stacking method(rawlinson & kennet, 2004), 4629 relative arrival time residuals were picked from 172 distant earthquakes. we estimate the uppermost mantle relative s-wave velocity structure beneath the northern zagros and western central iran using a nonlinear tomography method (rawlinson et al., 2006).
