The Tursac Interstadial is a warm phase in the Vistula High Glacial . It falls in the period 27,000 to 25,500 BC. Chr.

designation

The Tursac Interstadial was named after its eponymous French type locality Tursac in the Dordogne department . The deposits in the Abri du Facteur , which Henri Delporte described in detail in 1968, serve as a reference profile .

Stratigraphy and Correlations

The temporal position of the Tursac interstadial (marked in red) in the period 20 to 40 ka BP. Oxygen isotopes according to GISP 2.

The Tursac Interstadial follows the Maisières Interstadial . The cold setback of the Heinrich event H3 switches between the two interstadials . This was followed by the ice advance of the Brandenburg phase , which in turn was replaced by the Laugerie-Interstadial .

The Tursac Interstadial is made up of the two Dansgaard-Oeschger events DO3 and DO4 ( Greenland Interstadial GI-3 and GI-4 ).

In archeology it corresponds to the two levels Noaillien (DO4) and Rayssien (DO3).

Dating

The Tursac interstadial can be traced back to the period 27,000 to 25,500 BC using the GISP-2 oxygen isotope curve. Be classified. For Leroi-Gourhan (1988) it covers the period 23,500 to 22,500 radiocarbon years BP , which is calibrated (with CalPal) 26,374 to 25,286 years BC. Corresponds to. Laville (1988) gives 24,000 to 23,000 radiocarbon years (26,884 to 25,629 BC),

Bosselin (1996), however, recommends an older age of 26,500 to 24,500 radiocarbon years (29,334 to 27,350 BC) and Wolfgang Weißmüller reckons with 26,000 to 24,200 radiocarbon years (29,013 to 27,018 BC).

The Noaillien was dated with 26,500 to 25,000 radiocarbon years (29,013 to 28,028 BC), the Rayssien with 25,500 to 24,500 radiocarbon years (28,410 to 27,350 BC).

Environmental parameters

Oxygen isotopes

The δ ¹⁸ O values of the GISP 2 ice cores show an increase of 6.7 ‰ SMOW (from −42.7 to −38 ‰) for DO4 and a slightly lower value for DO3 compared to the previous cold setback of the Heinrich event H3 from 4 ‰ SMOW (increase from −41.5 to −37.5 ‰ SMOW).

Temperatures

According to GISP 2, the increase in the δ ¹⁸ O values is reflected in a very significant increase in temperature . In the Greenland Ice Sheet, this was an annual average of 14 ° C for DO4 and 13 ° C for DO3.

Cultural development

Noailles graver

During the Tursac Interstadial, the Middle Gravettia (or Périgordien ) with the levels Noaillien and Rayssien prevailed . The Noailles burins and the Raysse burins are characteristic of the tools of this era . Among the small works of art worth mentioning is the appearance of Venus figurines , for example the Venus of Tursac found at the type locality .
