  • The most widespread depositional landforms in many of the upland valleys of the British Isles which have undergone glaciation during the Last Glacial Maximum (LGM) are so-called solifluction sheets. This paper presents the first dates from
  • these landforms in the British Isles. The AA. used optical dating on deposits exposed at Linhope Burn in the Cheviot Hills of North East England. The results suggest that the bulk of sediment deposition at this site happened over a period spanning the Younger

  • The AA. compared the results of 4 independent reconstruction methods – optically stimulated luminescence (OSL) dating, caesium-137 (137Cs) dating, heavy metal analysis, and flood bed interpretation – applied at 3 embanked floodplain sites along
  • lower Rhine River distributaries in the Netherlands. Intercomparison of the results of the different dating methods revealed the potential errors associated with each method. Using the results the AA. indicate the optimal spatial range of application

  • Application date as a controlling factor of pesticide transfers to surface water during runoff events
