Holocene sedimentary sequences lacking organic remnants or containing redeposited material pose a challenge for detailed chronological investigations, as radiocarbon dating is unsuitable. Optically stimulated luminescence (OSL) can be used instead, but high-resolution OSL costly. A more cost-effective and efficient approach involves the combination of low-resolution with portable (pOSL) profiling in 5–10 cm increments (e.g. Sanderson Murphy, 2010; Brill et al. 2016). This method...
Marine sediments occupy a significant portion of the Quaternary succession in West Siberian Arctic but, until recently, their ages and distributions have been strongly debated. Based on new geological, palaeontological geochronological data obtained within last decade, we hereby postulate following: (i) Two different Pleistocene interglacial marine formations are exposed across Arctic. The older Kheta formation, sandwiched between two Middle till beds, yields optically stimulated...
ABSTRACT The quarry of the Sverdlov (Etalon) Factory stands out as a unique site in northwest East European Plain since it exposes an almost complete Upper Pleistocene stratigraphic succession. Previous investigations have revealed sequence marine sediments deposited during whole Mikulino Interglacial [Eemian, Marine Isotope Stage (MIS)5e], but chronology Late deposits remains incomplete and requires further update. We present study Middle–Upper units exposed by using geological methods,...
We present a composite section of the Upper Quaternary sediment beds and preliminary reconstructions Late Pleistocene sedimentation environments in southeastern White Sea Region, obtained as result field analytical research on coast Kuloi Plateau, generalization published evidence geological survey reports, together with correlation existing continental marine palaeoarchives.The studies included lithostratigraphic descriptions sections, linking lithological boundaries to absolute heights,...
Across the northern East-European Plain, and especially in Mologa-Sheksna Lowland (MSL), short-term climate variability Late Glacial caused significant palaeohydrological alterations, which drove vegetation successions. The MSL is prominent for dense river lake network, have evolved through multiple water level sedimentation regime oscillations since Last Maximum. Extensive bogs inherit morphology of basins, had been filled with paleolakes several millennia until their ultimate drainage...
We present the first results of a detailed rock magnetic and paleomagnetic research Mga marine interglacial sediments Mikulino (Eemian) Interglacial (the Upper Pleistocene) in Etalon section (former Sverdlov Factory, Leningrad Region). The Blake geomagnetic excursion was determined upper part formation according to shallow inclination characteristic remanent magnetization (ChRM) component. Age obtained as 117 ± 7 ka applying optically stimulated luminescence (OSL) dating. are good agreement...
Field lithostratigraphic studies, microfaunistic and palynological analyses, as well optically stimulated luminescence (OSL) dating revealed for the first time that lower part of Quaternary sediment sequences exposed along Zimnii Coast White Sea accumulated in marine nearshore environments during Boreal transgression at beginning Last Interglacial thus form Upper Pleistocene Mikulinian Horizon. This is confirmed by lithology beds; species composition foraminifers, ostracods aquatic...
