“…Les palynozones ainsi définies ont été corrélées à celles d'autres séries sédimentaires d'Europe, ainsi qu'avec les stades isotopiques marins OIS (Tzedakis et al, 2001 ;Reille et al, 1998 ;Guiter et al, 2003). Ces données chronostratigraphiques ont permis d'attribuer un âge aux différentes chronozones retenus pour le Pléistocène supérieur et l'Holocène de la séquence sédimentaire du Lac du Bouchet (tab.…”

“…However, the correlation of these deposits with the marine isotope record remains uncertain because climatic similarities between different interglacial stages as well as local environmental factors make it impossible to correlate patterns of vegetation development with any one particular interglacial stage (Tzedakis et al, 2001). In addition where absolute age estimates exist, different deposits with Hoxnian pollen affinities have been dated to both MIS 9 and MIS 11 (Bowen et al, 1989;Rowe et al, 1997;Grün and Schwarcz, 2000;Geyh and Müller, 2005).…”

The lowland region of north Norfolk contains some of the best preserved evidence for glacial deposition during the Middle Pleistocene in northwest Europe.Despite the importance of these deposits, there is limited chronological control and it is debated whether they belong to a single glaciation, equated to the Anglian glaciation (Marine Isotope Stage 12), or represent deposition over a number of Middle Pleistocene cold stages. In order to develop an improved chronology for glaciation in this region, we obtained 18 samples for optical stimulated luminescence (OSL) dating from glacial outwash facies. Samples of coarse-grained quartz sand were measured using the SAR (single aliquot regenerative-dose) protocol. The low radioactive isotope concentrations in sediments of this region enable the traditionally accepted age limit of luminescence dating to be extended. The form of the dose response curves, pre-heat plateaux tests, and dose recovery experiments also indicate that laboratory doses can be reliably measured in these samples. Age overestimation due to partial bleaching is thought to be insignificant. The OSL ages suggest that the glacial sediments studied were deposited during MIS 12 rather than in different post MIS 12 stages.

“…This general pattern of triplicate warm phases interrupted by two terrestrial cold periods (PAS Vb, PAZ Va2) is characteristic in both marine and ice core records (MIS 7e, 7c, and 7a after Lisiecki and Raymo, 2004) as well as for the continental pollen sequences in southern Europe correlated and synchronized by Tzedakis et al (2001).…”

“…Based on long continental records in southern Europe (compiled by Tzedakis et al, 1997Tzedakis et al, , 2001) and in the eastern Mediterranean area Stockhecke et al, 2014a), it was shown that there is a broad correspondence between warm climatic intervals, especially periods of low ice volume as defined by the marine isotope stage (MIS; Lisiecki and Raymo, 2004), and terrestrial temperate intervals (forested periods). In the continental semiarid Lake Van area, it is difficult to use only the expansion of trees as a criterion for the lower boundary of a warm stage.…”

Abstract.A new detailed pollen and oxygen isotope record of the penultimate interglacial-glacial cycle, corresponding to the marine isotope stage (MIS) 7-6, has been generated from the Ahlat Ridge (AR) sediment core at Lake Van, Turkey. The presented Lake Van pollen record (ca. 250.2-128.8 ka) displays the highest temporal resolution in this region with a mean sampling interval of ∼ 540 years.The integration of all available proxies shows three temperate intervals of high effective soil moisture availability. This is evidenced by the predominance of steppe-forested landscapes (oak steppe-forest) similar to the present interglacial vegetation in this sensitive semiarid region between the Black Sea, the Caspian Sea, and the Mediterranean Sea.The wettest and warmest stage, as indicated by highest temperate tree percentages, can be broadly correlated with MIS 7c, while the amplitude of the tree population maximum during the oldest penultimate interglacial (MIS 7e) appears to be reduced due to warm but drier climatic conditions. The detailed comparison of the penultimate interglacial complex (MIS 7) to the last interglacial (Eemian, MIS 5e) and the current interglacial (Holocene, MIS 1) provides a vivid illustration of possible differences in the successive climatic cycles. Intervening periods of treeless vegetation can be correlated with MIS 7d and 7a, in which open landscapes favor local erosion and detrital sedimentation. The predominance of steppe elements (e.g., Artemisia, Chenopodiaceae) during MIS 7d indicates very dry and cold climatic conditions. In contrast, the occurrence of higher temperate tree percentages (mainly deciduous Quercus) throughout MIS 7b points to relatively humid and mild conditions, which is in agreement with other pollen sequences in southern Europe.Despite the general dominance of dry and cold desertsteppe vegetation during the penultimate glacial (broadly equivalent to MIS 6), this period can be divided into two parts: an early stage (ca. 193-157 ka) with higher oscillations in tree percentages and a later stage (ca. 157-131 ka) with lower tree percentages and subdued oscillations. This subdivision of the penultimate glacial is also seen in other pollen records from southern Europe (e.g., MD01-2444 and I-284;Margari et al., 2010;Roucoux et al., 2011). The occurring vegetation pattern is analogous to the division of MIS 3 and MIS 2 during the last glacial in the same sediment sequence. Furthermore, we are able to identify the MIS 6e event (ca. 179-159 ka) as described in marine pollen records, which reveals clear climate variability due to rapid alternation in the vegetation cover.In comparison with long European pollen archives, speleothem isotope records from the Near East, and global climate parameters (e.g., insolation, atmospheric CO 2 content), the new high-resolution Lake Van record presents an improved insight into regional vegetation dynamics and climate variability in the eastern Mediterranean region.
