The chemical composition of sediments from the Reykjanes
Ridge is controlled by allochthonous and autochthonous processes. The
surface sediments are characterized by relatively high contents of calciumoxide
and strontium. Calcium and strontium dominate in the carbonate
phase due to the high content of biogenic carbonate. A high percentage
of iron and manganese are bound to oxides and hydroxides. An indication
of hydrothermal activity was not observed. A considerable portion of adsorbed
barium is transported in clay minerals. The higher amounts of
aluminium in glacial sequences indicate an enhanced input of terrigenous
material; the increase of stable bonding elemen~s points toward the large
influence of detrital minerals. The distinct differences in the bonding
characteristics of elements in these marine sediments in comparison to
fluvial and coastal - deposits could be due to the different environmental
