- Аннотация: Abstract. According to the hypothesis of A.A. Barenbaum(Barenbaum, 2010), changes in the fluxes of cosmic matterto the Earth can determine the mode of changes in thepolarity of the geomagnetic field. We made an attempt tofind a relationship between the behavior of thegeomagnetic field and variations in the intensity of theinflux of cosmic dust onto the Earth’s surface. Thedynamics of the influx of cosmic matter and itscorrespondence to the regime of geomagnetic inversionswas studied on the deposits of the Upper Cretaceous ‒Lower Paleogene, in the coastal outcrop of the river Volga(Mount Syrt), at the point with coordinates (50°43.001° N,45°38, 408° E). We found that the time of formation ofsedimentary horizons with high concentrations of nativemetal particles coincided with short-term episodes ofgeomagnetic polarity disturbance. This confirms thepossibility of the existence of a correlation between theintensification of cosmic dust flows and short-term polaritychanges (excursions) of the geomagnetic field.
