The position of the Matuyama-Brunhes boundary in different sections of the northwestern Black Sea loess-soil formation is located in the different stratigraphic horizons, which causes a lot of discussion. New paleomagnetic studies of the 55-meter Quaternary key section on the Dniester estuary near the village of Roxolany determine the Matuyama–Brunhes boundary at a depth of 46.6 m between the Lubny and Martonosha soil horizons. This agrees with modern knowledge of Ukrainian scientists about Quaternary records in south Ukraine and is not consistent with the results, which identified this boundary at a depth of 34 m in loesses above the level of PK7. The primary component of the natural remanent magnetization and their polarity were identified both in loess and soil horizons due to the detailed measurements on modern equipments.
