%X Rodríguez-Ramírez and Yáñez-Camacho (2008), Rodríguez-Vidal et al. (2009) and Rodríguez-Ramírez et al.(2009) have kept an ongoing discussion about the validity of radiocarbon ages in reconstructing Holocenepalaeogeographical models in the Gulf of Cadiz. The discussion considered the validity and correctness of the ΔRvalue to beused in the area to calibrate radiocarbon ages ofmarine samples. These papers suggest that theΔR valueproposed by Lario (1996) and Dabrio et al. (1999, 2000) is erroneous, and consequently, that all the evolutionarymodels based on radiocarbon ages from marine samples that have been proposed in this area since 1996 must berevised.However, the papers commentedhere use erroneously the R, regional R andΔR values.After reviewing thepublished data, it is apparent that the most reliable values of ΔR in the Gulf of Cadiz for middle-late Holocenesamples range between ΔR=35±85 yr and ΔR=95±15 yr. This means that the values used in Lario (1996) andDabrio et al. (1999, 2000) fall in this range, and also that the calibrated ages used by several authors adopting thesevalues are fully reliable. Calibrations using ΔR values inside this range do not yield significant differences in termsof geological age owing to the magnitude of errors resulting from the methods employed.
