“…IRSL dating was performed at the Leibniz Institute for Applied Geophysics, Hanover, Germany. The dates obtained by Sycheva et al [49] from the infill of buried balka were systematically older than the dates reported in this study (see Figure 15B). The main cause for this could be the difference in the methods used in these two laboratories and different minerals taken for dating.…”

“…The main cause for this could be the difference in the methods used in these two laboratories and different minerals taken for dating. Presumably, some IRSL dates reported in [49] are systematically older than those in Table 2 due to the much longer time needed for the zeroing of feldspars compared to the quartz used in OSL dating. However, according to both groups of dates, the three lower meters of the sedimentary fill in the main erosion feature were deposited quite rapidly.…”

“…Episodes of rapid sedimentation were followed by phases of stabilization of the sides and bottom of the balka. Four paleosoils-Kukuyevo, Streletsk, Aleksandrovsk (local terms suggested by Sycheva [45,49] and Bryansk paleosoil-are found above the main Salynsk paleosoil of the Mezin SC. The main deposition phase took place between the formation of the Salynsk and Kukuyevo paleosoils.…”

“…Recently, Sycheva et al [49] reported four more luminescence (IRSL) dates from the wall of the Aleksandrovsky quarry (generalized positions of the samples is shown in Figure 15B). IRSL dating was performed at the Leibniz Institute for Applied Geophysics, Hanover, Germany.…”

Networks of dry valleys (or balkas) and hollows in the upper reaches of fluvial basins in extraglacial areas in the Penultimate Glaciation (Marine Isotope Stage 6—MIS 6) regions of the East European Plain demonstrate clear incision/aggradation rhythms corresponding to global glacial/interglacial climate cycles. The first phase of each incision/aggradation rhythm began after the global glacial maximum and was characterized by a cool and humid climate, permafrost and sparse vegetation, when high surface runoff and active linear erosion formed a dense network of gullies. The second phase occurred at the glacial–interglacial transition and the subsequent interglacial period with its warm and humid climate and dense vegetation. This phase was distinguished by the partial filling of fluvial forms with slopewash deposits, the transformation of gullies into dry valleys (balkas) and the subsequent stabilization of fluvial forms marked by the formation of mature soils on the sides and bottoms of balkas. The third phase of the rapid accumulation of balkas developed during the cold and dry part of the next glacial epoch, resulting in the balkas becoming shallow hollows filled in with sediments. The last full incision/aggradation rhythm occurred in the late MIS 6 to mid-MIS 2. The erosion network formed during the late MIS 6 was almost completely filled by mid-MIS 2, and its manifestation in the modern topography is limited to a network of shallow hollows in the upper parts of the fluvial systems. The modern (incomplete) incision/aggradation rhythm began in the late MIS 2 and caused the formation of the modern erosion landscape in the upper reaches of fluvial systems. This rhythm is now in the stabilization phase, and the main accumulation phase of this rhythm is still far in the future.

“…51 000 and 42 000 years BP (Taratunina et al, 2021). Likewise, at the Alexandrovsky Quarry in the Central Russian Plain, the Alexandrov Paleosol is bracketed by OSL dates between 53 000 and 43 000 years BP (Sycheva et al, 2020). In some localities in the upper Volga region unnamed soil horizons have also been bracketed to times between the Mezin Pedocomplex and the Bryansk Paleosol (Sedov et al, 2016) Furthermore, pollen and phytoliths, as well as the traces of a root system show that it is probably a steppe or woodland steppe soil.…”
