  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.
