A suite of quartz samples of different provenances, irradiation, thermal and depositional histories were analysed using spectroscopic ionoluminescence (IL) to investigate variations in emission spectra as a function of cumulative radiation dosing. Protons were selected for implantation to mimic the effect of natural radiation over geological timescales. All samples exhibited depletion in the UV-violet emission (3.2-3.4 eV) with increasing cumulative dose, whilst the red emission (1.8-1.9 eV) increased. A power-law relationship exists between the two emissions. It is inferred that the luminescence emission of quartz is indicative of its radiation history, and spectral analyses could be used to determine the utility of different quartz samples for optically stimulated luminescence dating (OSL) where the detection range is limited to 3.4-4.6 eV.

AbbreviationsIonoluminescence (IL), Ultra-violet (UV), Optically Stimulated Luminescence (OSL) IntroductionOSL is used as a radiation dosimeter method within Quaternary geochronology, archaeology and retrospective accident dosimetry. Of the materials used for OSL studies, quartz is usually preferred (Aitken, 1998;Huntley et al., 1985). In addition, quartz has a range of industrial applications, which has rendered it the focus of intense research both into its physical and chemical properties, and its emission spectroscopy (see Götze, 2009; Krbetschek et al., 1997 for reviews). Numerous OSL dating applications to sediments of different ages (e.g. Ballarini et al., 2003;Pawley et al., 2008), provenances (e.g. Preusser et al., 2006) and depositional environments (e.g. Thrasher et al., 2009;Wallinga, 2002) have been made. However, despite the development of the single-aliquot regenerative dose protocol (Murray and Wintle, 2000), it is currently not possible to date all quartz using OSL. This is often due to quartz's highly variable OSL quantum efficiency (QE). The controls over quartz OSL QE remain unclear but have been linked to geological provenance (Götze et al., 2004;Rink et al., 1993;Westaway, 2009), irradiation (Rink, 1994, transport and thermal histories (Pietsch et al., 2008;Preusser et al., 2006). However quartz with the same irradiation, source and depositional histories often exhibit highly variable emission intensities McFee and Tite, 1998).The light emitted by quartz most commonly comprises bands in the UV-blue and red/IR (Krbetschek et al., 1997). Risø readers, the most widely used OSL instrumentation, stimulate the quartz with diodes at 470±20 nm (2.6 eV) and measure the response through Hoya U340 filters . The transparency of these filters lies between 3.4 and 4.6 eV and only a part of the UV-blue emission band is monitored. The remainder of the emission (below 3.4 eV and above 4.6 eV) is unmeasured in conventional OSL but may contain significant dosimetry or geological provenance information.Ionoluminescence (IL, also known as ion beam lumin...

“…Optically stimulated luminescence dating works well when applied to aeolian, coastal marine and shallow-water fluvial sediments (e.g., Rittenour 2008) as well as for sediments from deepwater marine or fluvial deposits (Murray and Olley 2002). Within these sediment types, most quartz-bearing sand materials from a few years (Ballarini et al 2003) to more than 150 000 yr old can be dated (Lian and Roberts 2006). When applied to chronosequences, most dune sequences, beach ridge plains, fluvial terraces or glaciofluvial deposits younger than Â150 000 yr can be dated through OSL dating.…”

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.

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 .

This study analyzes the optically stimulated luminescence (OSL) characteristics of quartz grains from fluvial, eolian and shallow marine sands of northeastern and southeastern Brazil, with especial focus on the applicability of the single-aliquot regenerative dose (SAR) dating protocol. All analyzed Brazilian sediments presented relatively high OSL sensitivity and good behavior regarding their luminescence characteristics relevant for radiation dose estimation. However, some samples from the Lençóis Maranhenses region in northeastern Brazil showed inadequate OSL sensitivity correction, hampering the implementation of the SAR protocol and their ability to behave as a natural dosimeter. While the shallow marine and eolian samples showed a narrow and reliable dose distribution, the fluvial sample had a wide dose distribution, suggesting incomplete bleaching and natural doses estimates dependent on age models.
