Problems of magnetostratigraphy of Pleistocene loess-soil deposits of the South of Ukraine
Main principles of magnetostratigraphy, paleomagnetic method of measurement and its applying in Quaternary stratigraphy have been set forth. Results of Matuyama-Brunhes (M/B) boundary detection in loess-soil sediments of Ukraine and other territories given in the previous studies are presented. Atte...

Attention has been paid to contradictions in determination of M/B boundary position and episodes of inverse polarity within Brunhes chron according to the data of different authors. The situation is notably shown on Roxolany section in West Black Sea region as an example. One of the reasons there can be increase of magnetometric equipment precision and quality of measurements which exclude the bias effects nowadays. Another reason is the contradictions in stratigraphic partition of sections that are located even within the same loess province.
