Variations of paleointensity in the Paleogene

Behavior of the geomagnetic field intensity in the Paleogene from sedimentary rocks of the Russian Plate was investigated. It is revealed that in the beginning of the Paleogene alternating of paleointensity variations of little amplitude (about 0.5 Ho, where Ho is the value of modern geomagnetic field taken as 40 mkT) and bursts of large amplitude (up to 5 Ho) took place. At the end of the Paleogene paleointensity variations occur only with a little amplitude.
