sediment traps on Lanzarote (Canary Islands) as a key for the
interpretation of a palaeoclimate archive off NW Africa (2009) -
On Lanzarote (Canary Islands) Late Quaternary Saharan dust and
volcanic material were trapped in Miocence to Pliocene valleys
dammed by volcanic lava flows. These trapped sediments are
potentially interesting as they can be natural archives useful
to reconstruct the terrestrial palaeoclimate history of the NW
African margin. Nevertheless, slope wash processes altered the
primarily eolian deposits, making climatic interpretation not
straightforward. Geomorphological mapping, GIS calculations and
sedimentological investigations were used to unravel these
processes influencing the temporal resolution of the
palaeoclimatic archive, demonstrating that they average the
palaeoclimatic signal by some ka. Thus, despite the colluvial
geomorphic environment, the valley fillings can be used for
palaeoclimatic interpretation of events wit
