1 janv. 6500 av. J.-C. - Brexit

Description:

c.6500 BC - England becomes separated from European continent by rising water levels.
- there was isostatic uplifting of land as a result of melting ice in eastern part Denmark (pressure of land ice disappeared;
- North sea land becomes submerged by water and sediment
- non preservation of Mesolithic site
-> in Dutch delta c.15 m below sediments or in the North sea:
-> Waterlogged condition = good preservation organic material

> the environmental consequences of global warming (tundra becomes deciduous forest; drowning of land; new ecological niche; formation of North Sea;
- c. 6500 BC, England becomes separated from European continent by rising water levels; - there was isostatic uplifting of land as a result of melting ice in eastern part Denmark (pressure of land ice disappeared;
- around North Sea (England-Netherlands): land became submerged by water and sediment;
- consequences of these developments for the (non)preservation of Mesolithic sites: in Dutch delta: Mesolithic sites may be 15 m below sediments or in the North Sea and because of waterlogged conditions very good preservation of organic remains; in higher parts of eastern/southern Netherlands outside the delta, however, there was no such a sedimentation and usually only flint and stone artefacts survive;
