“…The absence of plateaux above about 330°C, where they are expected for well-bleached samples, we take to indicate that the grains had less than 2 h of sunlight exposure at the time of deposition. Similar effects have been noted for polymineral fine grains (Berger et al , 1991Berger 1990).…”

“…In the case of young dune sands, use of the R-gamma partial-bleach method is usually necessary to isolate the component of the TL that is readily bleached (Huntley 1985;Berger 1988) because of possible limited sunlight exposure at about the time of deposition (Huntley et al 1983;Huntley 1985;Readhead 1988;Tejan-Kella et al 1990;Berger et al 1991). Although this method can be accurate, its precision for young samples can be low because of the analytical errors that arise from deriving the difference between two similar auantities which have intrinsic scatter of the order of a few p&cent.…”

In this paper we describe our efforts to determine the formation chronology of a sequence of dunes on Buctouche Spit, a Holocene deposit on the northeast coast of New Brunswick. Optical dating, using infrared stimulation of K-feldspar grains, yielded ages ranging from 5 f 30 a for an embryo dune to 765 + 45 a for the oldest dune. Thermoluminescence ages, although less precise, support the recent formation of the dunes. The ages exhibit the expected seriation from youngest to oldest and are consistent with historical evidence coupled with an assumed constant sediment aggradation rate. The age resolution obtained was very good and we conclude that the optical dating method used here shows great promise.Dans le prCsent article, nous dCcrivons les travaux r6alisCs pour la dCtermination chronologique des 6tapes du dCveloppement d'une sCquence de dunes sur la flbche littorale de Buctouche, un dCp6t holocbne sur la c6te nord-est du NouveauBrunswick.

“…Since we would date the fine-silt fraction of the sand, we were aware of the possibility of obtaining only a lower limit to the deposition age due to possible postdepositional incorporation of vertically translocated fine-silt grains. However, Berger et al (1991) obtained reasonable TL ages from fine-silt grains in aeolian sand at a coastal site.…”

Westland is a key region in New Zealand for Quaternary stratigraphy; however, the regional glacial chronology is largely unsupported by numerical ages because of the unreliability of radiocarbon dating in this high-rainfall region. Therefore, we tested the ability of thermoluminescence (TL) and infrared-stimulated luminescence (IRSL) to produce stratigraphically consistent age estimates in this area. At Blue Spur Road, we obtained a stratigraphically reasonable TL age of 47 ± 7 ka in the second buried E horizon and a perhaps underestimated 53 ± 16 ka in the lower part of the fourth buried Bs horizon. A marine sand underlying Waimea outwash gave an incorrect (underestimated) IRSL age of c. 44 ka. In Saltwater Forest we collected five samples from two loess profiles overlying glacial moraines. Only one TL age (36 ± 3 ka in the lower part of the first Bs horizon) is acceptable. The next lower sample (c. 1.2 m), stratigraphically probably younger than 125 ka, gave a reasonable IRSL age of 89 ± 15 ka. In trench M1/1, on an older moraine, two TL age estimates were stratigraphically reversed, with a third result (87 ± 30 ka in unit L4) being reasonable. In contrast, IRSL produced ages of 65 ± 16 ka (1.1 m) and 145 ± 36 ka (2.0 m) for the upper two samples, removing the TL-age reversal, although the age of the lower sample may be an overestimate. The third IRSL result (36 ± 5 ka, 2.7 m) is much too young, like the corresponding TL result. Thus, although TL is generally unreliable in the highly weathered loess-paleosol sequences of Westland, the IRSL technique offers more promise, perhaps because of IRSL's feldspar specificity and its far greater signal-zeroing efficiency.
