The author applies a perturbation method to determine tidal deformations on a rotating, spherically asymmetric, visco-elastic, laterally heterogeneous and anisotropic Earth. He shows that the deviations from tides on a nonrotating spherical Earth are on the order of one per cent. This applies to the effects of rotation, ellipsoidal shape of the Earth, visco-elasticity, lateral heterogeneity and anisotropy in the mantle, separately. With respect to the effects of rotation and ellipticity he finds significant quantitative discrepancies from what was accepted so far. With respect to lateral heterogeneities in the mantle he argues that visco-elastic dispersion is responsible for a considerable amplification of the heterogeneities when moving from seismic to tidal frequencies. On this basis, he suggests tidal tomography as a new rool for studying temperature induced mantle anomalies with modern space techniques.

The Author: Rongjiang Wang was born in 1955 in China. From 1978 to 1981 he studied physics in Anhui. From 1982 to 1983 he studied geodesy and geophysics in the Chinese Academy of Sciences. In 1984 he came to the University of Kiel, Germany, and graduated as Dr. rer. nat. in 1991.

Contents: Perturbation method - Effects of rotation and ellipticity on Earth tides - Visco-elastic relaxation and dispersion - Tidal tomography and mantle heterogeneity.
