The Lascaux-Interstadial is the second warm phase after the last ice age maximum . It happened in the period 19,000 to 18,000 BC. BC , in a broader sense also up to 16,000 BC Chr.

designation

The Lascaux-Interstadial was named after its eponymous type locality Lascaux near Montignac in the Dordogne department . However, the Laugerie-Haute and Les Jamblancs deposits near Bourniquel (both Dordogne) serve as reference profiles .

Stratigraphy and Correlations

The Lascaux-Interstadial (marked in red and orange) within a time frame of 10 to 30 ka BP. Oxygen isotopes according to GISP 2.

The Lascaux-Interstadial follows the intermediate cooling phase DV 3-4 (around 19,300 BC - recognizable as an ice wedge event in a wet soil horizon of Dolní Věstonice ) on the Laugerie-Interstadial . After the actual warm phase of the Lascaux-Interstadial in the narrower sense of the word, the warming trend continued, so that the Lascaux-Interstadial in the broader sense after a very brief cooling still up to 16,000 BC. Chr. Continued. Only then did the temperatures fall again in the direction of the cooling phase DV 6-7 (around 13,900 BC).

The Lascaux-Interstadial belongs to the marine isotope stage MIS 2 and falls into the Greenland-Stadial GS-2 ( GS-2b ).

It is situated between the previous Frankfurt phase and the subsequent Pomeranian phase of the Fennoscan Ice Sheet . The intermittent cold relapse around 18,200 BC. BC correlates with the LGM-2 of the last glacial maximum .

Dating

On the basis of the course of the δ ¹⁸ 0 values of the Greenland ice core GISP 2 , the Lascaux-Interstadial can approximate the time span 19,000 to 18,000 BC. Be assigned. Arlette Leroi-Gourhan (1988) gives 17,800 to 16,500 radiocarbon years BP for the interstadial , which is 19,326 to 17,865 years BC when calibrated (with CalPal). Corresponds to. The same period is advocated by Laville (1988). Bosselin and Djindjian (1988) recommend 18,000 to 16,200 radiocarbon years and 19,763 to 17,380 BC, respectively. Chr. Wolfgang Weißmüller sets the beginning of the Lascaux-Interstadial with 17,500 radiocarbon years or calibrated with 18,972 years BC. As already mentioned, the Lascaux-Interstadial can be traced back to around 16,000 BC in the broader sense. To expand.

characterization

Based on the GRIP data, the increase in the δ ¹⁸ 0 values from the low of the previous DV 3-4 stadial to the Lascaux interstadial was around 3 ‰ (from −42 to −39 ‰) SMOW . This corresponds to a temperature increase of 6 ° C in the Greenland ice . The values then sank again to −41 ‰ SMOW. By the end of the extended interstadial, they then rose again to -39 ‰. During the extended interstadial, the temperatures were up to 2 ° C higher than in the actual interstadial.

Volcanism

In the course of the Lascaux-Interstadial, the Eltville Tuff , an important stratigraphic correlation horizon , was deposited in loess sediments of the outgoing Vistula Late Glacial in Central Europe . It is around 19,000 to 18,000 years BC. Dated.

Cultural development

The Lascaux-Interstadial is culturally shaped by Badegoulien . The Older Badegoulien (formerly Magdalenian 0 ) had just come to an end and the Younger Badegoulien ( Magdalenian I ) was spreading. The extended Interstadial also saw the beginning of Magdalenian ( Magdalenian II ).
