OSL and ESR studies of Aeolian quartz from the Upper Pleistocene loess sequence of Nussloch (Germany)
H Tissoux, H Valladas, P Voinchet, JL Reyss… - Quaternary …, 2010 - Elsevier
As part of a chronological study of the famous Upper Pleistocene Nussloch (Germany) loess
sequence, three samples were collected to check the applicability of palaeodosimetric
dating methods (OSL and ESR) to quartz grains. The ESR-multicentre method showed a
partial bleaching of the ESR centers in aeolian sands. This partial bleaching was also
observed by OSL. Laminated loess seemed to be sufficiently bleached but showed a large
scatter of the doses, which we ascribed to heterogeneous responses of the luminescent …
