The lithosphere-asthenosphere boundary beneath the western United States

Geoelectrical Structure of the Lithosphere and Asthenosphere beneath the Northwestern United States

We have inverted magneto telluric (MT) data collected in nine states of the northwestern United States as a part of the EarthScope project for 3D imaging of electrical resistivity to a depth of 500 km using recent advances in extremely largescale electromagnetic modeling and inversion. The results of our mega-cell 3D inversion reveal multi-scale geo electrical in homogeneities in the upper mant...

Variation of Lithosphere-Asthenosphere boundary beneath Iran by using S Receiver function

The current geological and tectonic setting of Iran is due to the ongoing convergence between the Arabian and Eurasian Plates, which resulted in the formation of the Iranian plateau, mountain building, extensive deformation and seismicity. The Iranian plateau is characterized by various domains including the continental collision and the oceanic plate seduction. Based on S receiver functions ar...

Stratified seismic anisotropy and the lithosphere- asthenosphere boundary beneath eastern North America

Long records of teleseismic observations accumulated at permanent seismic stations Harvard, MA; Palisades, NY; and Standing Stone, PA, in eastern North America are inverted for vertical distribution of anisotropic parameters. High-resolution anisotropy-aware P wave receiver function analysis and multiple-layer core-refracted SKS waveform modeling favor more than one layer of anisotropy beneath ...
