Abstract

The aim of this study is to obtain new information on the density structure of the European upper mantle by incorporating the state-ofthe-art global gravity data derived from the GOCE satellite gravity mission and recently released seismic model for the crustal structure, EUNAseis.The residual mantle gravity anomalies are derived from the GOCE data, from which gravitational effects of the deep mantle and the crust are removed. Our model of mantle density structure has lateral resolution of ca. 100 km, which allows to distinguish small-scale mantle anomalies and to link them to regional geodynamic processes. Given a relatively small range of expected density variations in thel ithospheric mantle, knowledge on the uncertainties associated within complete knowledge of density structure of the crust is of utmost importance for further progress in density heterogeneity studies.Therefore, we examine the propagation of crustal model uncertainties into determinations of lithospheric mantle density.
