Distribution of polycyclic aromatic hydrocarbons in eolian and eolian-deluvial sediments from the North Iceland
This work considers results of a study of Holocene cover sediments in Iceland. They are largely composed of wind-transported palagonitized hyaloclastite particles and coeval horizons of acid and basic tephras. It is established that polyciclic aromatic hydrocarbons (PAH) are released from basaltic g...
