“…But very few applications of luminescence dating in relation to soil development have been published. Botha and Porat (2007) and Singh et al (2007) used infrared luminescence dating on feldspars to assess the soil development of South African coastal plain and Indian floodplain sediments, respectively. Blue-light quartz OSL and feldspar infrared luminescence dating were applied by Ufnar (2007) to date river terraces in Mississippi, United States, and assess the soil development rates.…”

M. 2010. Soil development rates from an optically stimulated luminescence-dated beach ridge sequence in Northern Jutland, Denmark. Can. J. Soil Sci. 90: 295Á307. Rates of podzolic soil development in sandy, temperate soils were quantified based on 14 soil pedons with five substrata from a beach ridge chronosequence near Jerup, Northern Denmark (578N). Soil pH, organic carbon (C) as well as extractable iron (Fe) and aluminium (Al) were measured. The age of each pedon and soil stratum was measured by optically stimulated luminescence (OSL) dating and used to estimate soil development rates. Soils were divided into five groups from Typic Haplorthods and Entic Alorthods with a mean OSL age of 29659294 yr to Typic Quartzipsamments with a mean OSL age of 22911 yr. Acidification rates during the first 200 yr were Â1.9 pH units per 100 yr in the A horizons and C-sequestration rates wereÂ25 g C m (2 yr(1 (excluding litter accumulation). After Â1500 yr, the mineral soil C stocks stabilised around 13.092.0 kg C m (2 . Translocation rates of Al into B horizons were Â0.3 kg Al m (2 per 1000 yr, while translocation rates for Fe were scattered. Our study illustrates the potential of OSL dating in chronosequence studies to quantify soil development rates.Key words: Soil development rates, chronosequence, OSL-dating, C-sequestration rates and translocation rates Nielsen, A. H., Elberling, B. et Pejrup, M. 2010. Taux de de´veloppement du sol dans une se´quence de ride de plage date´e par luminescence stimule´e optiquement dans le nord du Jutland, au Danemark. Can. J. Soil Sci. 90: 295Á307. Les auteurs ont quantifie´le taux de de´veloppement des podzols dans un sol tempe´re´sablonneux a`partir de 14 pe´dons incluant 5 sousstrates issues d'une chronose´quence pre`s de Jerup, dans le nord du Danemark (578N). Ils ont mesure´le pH du sol, la concentration de carbone organique (C) ainsi que la proportion de fer (Fe) et d'aluminium (Al) extractible. L'aˆge de chaque pe´don et strate a e´te´e´tabli par luminescence stimule´e optiquement (LSO) ce qui a permis d'estimer le taux de de´veloppement du sol. Les sols ont e´te´re´partis en cinq groupes, de l'haplorthod typique a`l'alorthod entique, dont la LSO moyenne est de 2 9659294 ans, aux quartzipsamments typiques, dont la LSO moyenne se chiffre a`22911 ans. Le taux d'acidification au cours des 200 premie`res anne´es e´tait deÂ1,9 unite´pH par sie`cle pour les horizons A, tandis que le taux de se´questration du C s'e´tablissait a`Â25 g par m 2 et par anne´e (sans la couverture de´tritique). Apre`s Â1500 ans, la re´serve de C du sol se stabilise autour de 13,092,0 kg par m 2 . La translocation de l'Al dans les horizons B se situe a`Â0,3 kg par m 2 par 1 000 ans alors que celle du Fe varie. L'e´tude re´ve`le le potentiel de la me´thode de datation par LSO dans l'e´tude des chronose´quences pour mesurer le taux de de´veloppement du sol.
