First evidence for Holocene rainfall in the Tanezrouft hyperdesert and its margins

Fresh water lakelets existed between c. 10.2 and 5.5 ka B.P. along the margins of the Tanezrouft desert. Palaeosols have been observed on the plateau itself, above eolian formations nearby TL dated at 18-9 ka: they give evidence of a steppic vegetal cover of still unknown extension, even in this pre...

Zusammenfassung:Fresh water lakelets existed between c. 10.2 and 5.5 ka B.P. along the margins of the Tanezrouft desert. Palaeosols have been observed on the plateau itself, above eolian formations nearby TL dated at 18-9 ka: they give evidence of a steppic vegetal cover of still unknown extension, even in this present-day rainless desert.
