Аннотация:The behaviour of the geomagnetic field characteristics (mean values of the
paleointensity, amplitude of its variations and reversal frequency) during the last 170
million years was analyzed. It was found that the mean values of the paleointensity
were in direct relation to amplitude of its variations and in reverse relation to reversal
frequency. The most considerable changes of the Earth’s magnetic field
characteristics occurred in Early Cretaceous, Middle Paleogene and Neogene. The
analysis of conformity of the reconstructed characteristics behaviour of a geomagnetic
field to an aw- dynamo model was made.
