Crust and upper mantle of Kamchatka from teleseismic receiver functions
Teleseismic receiver functions (RFs) from a yearlong broadband seismological experiment in Kamchatka reveal regional variations in the Moho, anisotropy in the supra-slab mantle wedge, and, along the eastern coast, Ps converted phases from the steeply dipping slab. We analyze both radialand transverse-component RFs in bin-averaged epicentral and backazimuthal sweeps, in order to detect Ps moveou...
متن کاملSeismic Structure of the Crust and Upper Mantle in the Southwestern United States Using Teleseismic Receiver Functions
This dissertation describes the development of receiver function processing methods to create images of the seismic structure of the crust and upper mantle from teleseismic earthquake arrivals. These methods include receiver function estimation and prestack migration techniques which reduce deconvolution instability and produce regularized, multi-phase receiver function images. The receiver fun...
متن کاملLithospheric structure of the Pilbara Craton, Capricorn Orogen and northern Yilgarn Craton, Western Australia, from teleseismic receiver functions
The upper lithospheric structure from the Pilbara Craton, across the Capricorn Orogen, to the northern Yilgarn Craton is determined from high-fidelity broadband seismic data. Three-component temporary stations were deployed in a line running southwards from Marble Bar, Western Australia, at approximately 118 E longitude. They were in position between July and October 2000. Receiver functions ar...
متن کاملCrustal structure and upper mantle stratigraphy of the Arabian shield
[1] Analysis of receiver functions from an eight-station network on the Saudi Arabian shield indicates that the Moho depths vary between 35–38 km. The crust appears to be rather felsic in nature as evidenced by Poisson’s ratios of 0.25–0.27. A prominent negative phase following the Moho conversion is suggestive of a zone of velocity inversion. Indication of mantle stratification is observed ben...
متن کاملthe crustal structure beneath the northwest of the zagros (kermanshah region) from teleseismic receiver functions
in this study, we used teleseismic data which was recorded by 5 stations (dhr, ghg, kom, lin and vis) of the kermanshah seismic network from 2003 to 2007 with mb?5.5 and epicentral distances from 30° to 95°. the crustal structure beneath these stations was determined by the modeling of the p receiver functions. the main phases, which were observed in our final p receiver functions, are moho con...
