France) offers a unique paleoclimatic and paleomagnetic record of the last 130,000years. Several geomagnetic excursions are recorded implying rapid motions at the core/mantle interface. The data reveal a correlation between paleoclimate and the position
of the geomagnetic pole: during ice ages the pole was in the Siberian-Arctic region. There is a close correlation between paleomagnetic and paleogeoid changes implying a mutual origin in core/mantle changes. The astronomical variables in the Earth/Sun constellation
