Abstract

The aim of this study is to obtain new information on the density structure of the mantle below the Eurasian continent. For this we develop a methodology for regional density determination by combining seismic velocity data with gravity data derived from different sources, i.e. land gravity data, geopotential models and the GOCE gravity gradients. We show how uncertainties in the conversion from P-wave velocity to density propagate into the gravity model and the density model of the upper mantle. A particular focus of the study is on the development of a  new regional density model for the Siberian craton and the West Siberian Basin, which will complement an on-going study of the regional crustal structure as well as the uppermantle by seismic tomography for the region.
