  • Title: Insights on the upper mantle beneath the Eastern Alps.
    Author: Bianchi I, Miller MS, Bokelmann G.
    Journal: Earth Planet Sci Lett; 2014 Oct 01; 403():199-209. PubMed ID: 25843967.
    Abstract:
    Analyses of Ps and Sp receiver functions from datasets collected by permanent and temporary seismic stations, image a seismic discontinuity, due to a negative velocity contrast across the entire Eastern Alps. The receiver functions show the presence of the discontinuity within the upper mantle with a resolution of tens of kilometers laterally. It is deeper (100-130 km) below the central portion of the Eastern Alps, and shallower (70-80 km) towards the Pannonian Basin and in the Central Alps. Comparison with previous studies renders it likely that the observed discontinuity coincides with the lithosphere-asthenosphere boundary (LAB) east of 15°E longitude, while it could be associated with a low velocity zone west of 15°E.
