WebHere S 1111 α is the overall directional compliance expressed in a system where the axis 1 is along the tensile direction. Two factors affect the variation of E with α: the single … WebWe present empirical linear relationships between anisotropy and ellipticity for crustal rocks. The maximum out-of-plane conversion amplitudes in receiver functions scale linearly with degree of anisotropy for nonelliptical symmetry. The elliptical assumption results in a bias of up to 1.4 times true anisotropy. 1. Introduction
Lower crustal anisotropy or dipping boundaries? Effects on receiver …
WebMar 10, 2024 · We report a study using teleseismic P-wave receiver functions to infer the orientation of the maximum horizontal principal stress from the direction of upper crustal shear-wave velocity anisotropy. We apply an inverse approach using the Neighborhood Algorithm to conduct a nonlinear search, attaining a best-fitting crustal model that … WebSep 15, 2014 · The receiver function analysis technique isolates teleseismic mode conversions originating at velocity contrasts beneath a seismic station. We show that dipping isotropic contrasts as well as small (<10%) anisotropy generate first-order (i.e. Moho-sized) arrivals in receiver functions. cigar shop beograd
