Grain-size analysis of surface sediments, continental margin off NW Africa, supplement to: Holz, Christine; Stuut, Jan-Berend W; Henrich, Rüdiger (2004): Terrigenous sedimentation processes along the continental margin off NW-Africa: implications from grain-size analysis of surface sediments. Sedimentology, 51, 1145-1154

The terrigenous fraction of seabed sediments recovered along the north-west African continental margin illustrates spatial variability in grain size attributed to different transport mechanisms. Three subpopulations are determined from the grain-size analyses (n = 78) of the carbonate-free silt fraction applying an end-member modelling algorithm (G. J. Weltje, 1997). The two coarsest end-members are interpreted as representing aeolian dust, and the fine-grained end-member is related to fluvial supply. The end-member model thus allows aeolian fallout...
