The coversands along the Peel Boundary Fault in the Netherlands were investigated by a luminescence dating approach combining Infrared Optically Stimulated Luminescence (IRSL) and Thermoluminescence (TL) methods. At the Neer trench, ten samples were collected and investigated in order to set up an independent chronological framework for the deposition history of the fluvio-aeolian and aeolian sediments and hence the timing of Late Weichselian and Holocene earthquake events. Five sedimentary units could be distinguished by this chronological approach. The oldest fluvio-aeolian unit yielded a mean deposition age of 35.9 +/- 0.4 ka and is designated to correlate with the Middle Weichselian. An IRSL age estimate of 20.1 +/- 2.9 ka was determined for the sediment that most likely represents the Older Coversands 1, and a mean luminescence age of 15.1 +/- 1.2 ka for deposits just below the Beuningen gravel bed. The aeolian sediment from above the Beuningen horizon yielded an IRSL age estimate of 9.4 +/- 1.0 ka. The youngest deposits from the colluvial wedge yielded <6.9 +/- 0.7 ka BP, and so an earthquake event was likely to occur during the Middle or Late Holocene, as evidenced by the luminescence age estimates.
