## 6 Conclusions  
The OSL signal from quartz grains included in the coastal alluvial deposits of the Mero River Basin in the Ria de A Coruna (NW Spain) has allowed the estimation of a depositional age between 120 ky and 51 ky. Therefore, they are Upper-Pleistocene sediments and not Plio-Quaternary or Holocene. The analysed OSL signal from multigrain aliquots is characterised by a low intensity which is most probably related to low luminescence sensitivity, although this intrinsic factor contributes less than 5% to the increase in overdispersion (_OD recovery_) according to the recovery tests. For samples coming from metasedimentary lithology and affected by high overdispersion values (_OD_ > 20%) with respect to the central dose, a negative trend is observed, from which an increase in the proportion of potassium in silt leads to an increase in _Dr-beta_ and a decrease in _OD_. Statistical analysis of the data reveals the presence of unimodal and symmetrical distributions, with a good fit to a normal distribution. Based on these results, the absence of incomplete bleaching is interpreted as an extrinsic factor contributing to an increase in _OD_, and the CAM central age model is used to calculate a reliable _De_. There is chronological coherence between the ages calculated for the alluvial deposits of the Lower Mero River, as well as the age of other alluvial and fluvial coastal deposits on the NW Iberian Atlantic coast. Based on this chronology, these sediments of continental origin, many of them located on the present-day shoreline, were deposited as the sea level fell during the Last Glacial episode when the Ria de Coruna was transformed into a fluvial valley over 100,000 years.
