a comparative modeling approach of crustal study in the central alborz

results of velocity structure modeling in the earth's crust using a comparison approach of receiver function analysis and joint inversion of receiver functions with surface wave dispersion data are presented in this paper. seismograms of the teleseismic events that have been recorded on a broadband seismic station in the central alborz were used for data processing. velocity models that were computed by using both modeling methods show analogy the depth  discontinuities but differences in the absolute values of velocity. in addition, differences between computed models using different initial velocity models confirms that receiver function results are not a unique modeling method compared with the joint inversion results which show reasonable and stable values. both methods show 56km depth for the moho discontinuity.
