Description of anomalous magnetic field of the province of Central-Arctic Uplifts of Amerasian basin including Alfa Ridge, Mendeleev and Chukotka Uplifts has been given in the article. Its frequency-spectral characteristics have been studied. Existing view-points as to geological nature of anomalous magnnetic field of the main positive morpho-structures of Amerasian basin have been considered. Based on complex analysis of up-to date geologic-geophysical information the author comes to a conclusion that the province of Central-Arctic uplifts of Amerasian basin is a megablock of continental crust subjected to active manifestation of intraplate volcanism.
