Receiver function study in northeast Tibet and adjacent boundaries
… of the Moho geometry and constraints on the lithosphere-asthenosphere boundaries (LAB). The average crustal thickness is about 50km for the northeastern corner of the Tibetan plateau. The deepest Moho is found along the Kunlun Fault zone in the northern Tibetan plateau. We also observed the …

Enhanced imaging of deep lithospheric and shallow near surface structures through innovations in seismic interferometry and array processing.
… from a sharp, negative velocity gradient at the Lithosphere-Asthenosphere Boundary (LAB) at approximately 90 km depth. The detection of this event in a relatively high-frequency band, combined with its positive polarity in autocorrelograms, indicates a steep velocity gradient at the LAB …

Seismic imaging of the lithosphere-asthenosphere boundary with a dense broadband array in central California
… the lateral extent of interruption of the lithosphere-asthenosphere boundary (LAB). The study area spans the location of two plausible origins for the anomaly, the Monterey microplate (Wang et al., 2013) and Sierra Nevada batholith (Ducea & Saleeby, 1998). Results include 918 binned …

Surface heat flow and lithospheric thermal structure of the northwestern Arabian Plate
… for modeling the thermal structure of the lithosphere. Changes in the qs over a distinct lithospheric unit are normally directly reflecting changes in the crustal composition and therewith the radiogenic heat budget (e.g., Rudnick et al., 1998; Förster and Förster, 2000; Mareschal and …

Seismic Imaging of the Global Asthenosphere using SS Precursors
The asthenosphere, a weak layer beneath the rigid lithosphere, plays a fundamental role in the operation of plate tectonics and mantle convection. While this layer is often characterized by low seismic velocity and high seismic attenuation, the global structure of the asthenosphere remains poorly …

The geothermal potential of Luxembourg
… and structures as well as borehole data available in Luxembourg and the adjoining regions. A Bouguer map is used to get insight in the depth, morphology and structures in the Variscan basement buried beneath the Trier–Luxembourg Basin. The geological section of the old Cessange borehole is …
