Abstract
The first results of radiocarbon dating of the Gothenburg and Mono Lake paleomagnetic excursions identified in a sedimentary section of bottom sediments of Baunt Lake (Northern Transbaikalia) are presented. The exact geochronological positions of these excursions are 13.2 and 25.8 ka, respectively. The estimated time of existence of the paleomagnetic events of ~100 and 500 years for the Gothenburg and Mono Lake excursions, respectively, can serve as geochronological markers for understanding the real time over which such global changes in the Earth’s magnetic field can occur.
