NEW DATA ABOUT MATUYAMA-BRUNHES BOUNDARY IN ROXOLANY SECTION
From new palaeomagnetic data of 55-meter key section of Quaternary loess-soil sediments on the Dniester estuary near Roxsolany village the position of Matuyama-Brunhes boundary have been determined. Earlier this section had been studied by different research groups [Третяк, 1983; Третяк и др., 1987;...

Geological journal| Резюме: | From new palaeomagnetic data of 55-meter key section of Quaternary loess-soil sediments on the Dniester estuary near Roxsolany village the position of Matuyama-Brunhes boundary have been determined. Earlier this section had been studied by different research groups [Третяк, 1983; Третяк и др., 1987; Третяк и др., 1989; Tsatskin et al., 1998; Tsatskin et al., 2001; Dodonov et al., 2006; Gendler et al., 2006] and the position and ages of individual soil horizons caused much discussion. The primary component of natural remanent magnetization and their polarity was identifying both in loess and soil horizons due to detail measurements on the modern equipments. Position of Matuyama-Brunhes boundary has been identified at a depth of 46.6 m between Martonosha and Lubny soil horizons. This is agree 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 РК7. |
