P-And S-Receiver Functions Analysis and Joint Inversion: Lithospheric Structure Below Erzurum Vicinity

Abstract

The receiver function technique is frequently used by geophysicists to determine discontinuities and to suppose the layer thicknesses in the crust and upper mantle. A receiver function is a time series in which phases are converted from P to S or S to P. In this study, the time-domain deconvolution method, depth and slowness stack, and the joint inversion algorithm are performed. In the aim of the study, teleseismic data is selected for the recorded at SENK and ECAT stations located in Erzurum city. P-and S-wave velocities, and Vp/Vs ratios are calculated for the lithospheric structure beneath these stations. The results of this study are generally consistent with previous receiver function findings applied in the study region. © 2023, Hacettepe Universitesi Yerbilmleri. All rights reserved.
