Kogan, M.G., Fairhead, J.D., Balmino, G. and Makedonskii, E.L. (1994). Tectonic fabric and lithospheric strength of northern Eurasia based on gravity data. Geophysical Research Letters 21: doi: 10.1029/94GL02550. issn: 0094-8276.

The isostatic gravity anomalies over the whole former USSR (FSU) from land gravimetry are presented here for the first time at a spatial resolution adequate to study the tectonic fabric and the lithospheric rigidity. The short wavelength gravity anomalies improve the delineation of the regional tectonic units of the FSU, originally identified from the geological and aeromagnetic data. A study of the coherence between the Bouguer gravity anomaly and topography of East European and Siberian Cratons allowed us to estimate the elastic plate thickness Te of 78 to 109 km. Relying on the current knowledge of the thermal state of Archean lithosphere, we inferred from Te the thermal plate thickness Tp of 200--250 km. ¿ American Geophysical Union 1994
