“…It is worth mentioning that the material of palaeobotanical investigations confirms the assumption that sediments of Blake Event accumulated during the climate optimum (Baltrūnas et al, 2013). The fact that the end of the Blake Event coincides with the end of spread of Corylus and Quercus and the beginning of spread of Carpinus has been determined recently in Germany.…”

Abstract:The interglacial deposits in the South Lithuanian Snaigupėlė outcrop and borehole Snaigupėlė-705 are marked for different bedding conditions though the sections are in proximity of each other. In the borehole section, the interglacial deposits are thicker and bedding at a greater depth than the analogous deposits of the outcrop. In the Snaigupėlė outcrop, the highest compatibility of isochronic-correction dates, calculated using L/L (method of leaching) and TSD (method of total sample dissolution) models, was determined for combination of three samples. With the help of the f value (section of isochrones in the axis of ordinates), the contribution of the primary pollution with thorium was determined where, as based on corrected analytical data, isochronic-correction dating was performed:

“…Scholger and Terhorst (2013) identified the Blake Event in a Loess sequence in Wels-Aschet (Austria) based on VGP latitude values of around À10 e5 , clearly corresponding to not fully reversed orientations. Baltrunas et al (2013) published palaeomagnetic data of the Netiesos section in southern Lithuania. Their lacustrine sediments yielded palaeomagnetic data in which the ChRM directions during the Eemian show great variability and a combination of both excursional and normal ChRM directions.…”

a b s t r a c tA palaeomagnetic study of the Last Interglacial calcareous tufa sequence at the archaeological site of Caours (northern France) identified a geomagnetic excursion that we interpret as the Blake Event. Earlier palaeontological (molluscs, mammals) and geochemical proxy studies at this site allowed recognition of full interglacial conditions prevailing during the deposition of the tufa sequence. The tufa sequence and associated Palaeolithic levels have been dated to the Eemian interglacial by a set of TIMS U/Th measurements on calcitic concretions (average : 123 ± 3 ka). By previous correlations of the Blake Event with the Eemian sensu stricto (as defined in the Netherlands) pollenzones at Neumark Nord 2 (Germany) and Rutten (The Netherlands) it has been shown that the continental Eemian starts after the peak of Marine Isotope Stage (MIS) 5e. The identification of the Blake Event at Caours implies a post MIS 5e peak age for all four levels of the Palaeolithic occupation. In perspective of the time lag between the MIS 5e peak and the beginning of the Eemian identified in other studies, it is very likely that during the main occupation of Caours a significant barrier was in place between north western France and Great Britain, in the form of the English Channel. It is possible that the chronological position of the Last Interglacial environments in northwestern Europe in relation to sea-level change is a key factor behind the apparent absence of Last Interglacial Palaeolithic sites in Great Britain.

“…Zagwijn, 1961). This is due to a decrease in sedimentation rate as a result of a dry phase in and around the Neumark basin, to which small basins are sensitive (Sier et al, 2011;Bakels, 2012). The Rutten site was not, or less hydrologically sensitive to such dry phases because of its position in the lower Rhine delta.…”

a b s t r a c tMultidisciplinary analysis including paleomagnetic, sedimentologic, sea-level change, luminescence dating and palynologic research was performed on a 25 m long orientated core taken at Rutten, close to Eemian key localities in the Netherlands. The main goal of our research was to test a possible delayed onset of temperate conditions in this region compared to Southern Europe, occurring within the Last Interglacial. The sediments revealed the presence of the paleomagnetic Blake Event in ca. 10 m of lowerdeltaic floodbasin sediments that contain a pollen record covering the Eemian. The position of the Blake Event in relation to the pollen stratigraphy concurs with the earlier studied Neumark Nord 2 site. Paleomagnetic correlation to core MD95-2042 off SW Iberia indicates ca. 5 kyr diachroneity between the pollen-based onset of temperate interglacial conditions between northern and southern Europe. The onset of the Eemian in north-western and central Europe (ca. 121.0 ka) post-dates the Marine Isotope Stage 6/5e transition by ca. 10 kyr. In addition, the Rutten data provide evidence for a relatively long duration of the Blake Event of at least 8 kyr. The late onset of the temperate conditions that define the base of the Eemian, imply that NW Europe with the Eemian type area is not the most suited region to define the beginning of the Last Interglacial and Late Pleistocene for global chronostratigraphic use.
