TL;DR: In this article, an alternative method based on importance sampling through calibrated dates is proposed, which works with calibrated radiocarbon as well as other dates, and provides a simple, systematic, transparent, documented and customizable alternative.

TL;DR: In this paper, the authors investigate which combination of time intervals will produce the net signal most dominated by the fast component, while keeping an acceptable level of precision, and they find that the signal most dominant by fast component can be obtained when the background integral immediately follows the initial signal and is approximately 2.5 times its length.

TL;DR: In this paper, a 10 Be production-rate calibration derived from an early Holocene debris-flow deposit at about 1000m above sea level in the central Southern Alps, New Zealand, in the mid-latitude Southern Hemisphere was presented.

TL;DR: In this article, the authors conducted a comprehensive examination of the 14 C content of the most common small terrestrial gastropods in North America, including 247 AMS measurements of modern shell material from 46 different species.

TL;DR: In this paper, the use of simple luminescence intensities, depletion rates and signal ratios is introduced which act, together with field gamma spectrometry, as proxies for underlying luminecence age, sensitivity and dosimetry within stratified sequences.

TL;DR: In this paper, the luminescence characteristics of fine-grained quartz extracts are investigated to some extent, and indicate that the applied laboratory measurement procedure (SAR) is reliable.

TL;DR: Balco et al. as discussed by the authors used 3He measurements in olivine from a well-dated lava flow at Tabernacle Hill, Utah, USA, to calibrate the local 3He production rate.

TL;DR: In this article, the results of a U-Th dating project at Qesem Cave, a Middle Pleistocene, late Lower Paleolithic site in Israel, were presented.

TL;DR: In this article, the authors proposed a method for consistent calibration of marine 14C dates from Arctic Canada using regional reservoir offset values (ΔR) for eight oceanographically distinct regions.

TL;DR: In this paper, a thick Middle and Late Pleistocene loess-palaeosol sequence is exposed at the Stari Slankamen section in the Vojvodina region situated in the south-eastern part of the Pannonian basin, Serbia.

TL;DR: In this paper, the evolution of fluvial systems and the human settlements of this area during Lower and Middle Pleistocene were investigated using electron spin resonance (ESR) data.

TL;DR: In this article, it has been shown that the lake level 120 m higher than today occurred at around 12-k. Most of these previous ages were obtained using 14C dating or multiple-aliquot IRSL/OSL dating.

TL;DR: In this paper, the authors investigated a section comprising lacustrine and shoreline deposits, which was about 25 m above the present lake level, and collected seven samples for quartz optically stimulated luminescence (OSL) dating.

TL;DR: A geochronological framework for the sequential development of coastal barrier aeolianite complexes in the mouth region of the River Murray, Australia's largest river system is presented based on amino acid racemization and thermoluminescence dating as discussed by the authors.

TL;DR: In this paper, the age of 12 luminescence samples from a chronologically well-constrained site dating to 450 ka from the Thames terrace sequence, southern Britain, was measured using SAR in order to test the performance of the method close to its upper age limit.

TL;DR: In this paper, a previously undated tephra south of Las Tres Virgenes volcano yielded U-Th and (U-Th)/He zircon ages overlapping those of La Virgen tephras, which suggests that both units are identical.

TL;DR: In this paper, the authors investigated the residual OSL signals in modern fluvial sand and suspended-sediment samples from the middle reach of the Yellow River and found that the residual equivalent dose (D e ) is found to vary with grain size, mineralogy and the techniques used for the determination.

TL;DR: In this paper, optically stimulated luminescence (OSL) has been applied to fine grain quartz samples to constrain the pollen chronology of a long sedimentary core taken at Azzano Decimo in the Friulian foreland of northeastern Italy.

TL;DR: In this article, a 2.3-million-year-old speleothem was found in a cave in South Africa and was used to provide valuable chronological constraints for hominin fossil-bearing cave deposits.

TL;DR: In this article, the authors used a single-aliquot regeneration-dose protocol to date 10 samples collected from four sections in the Xiao Qaidam Lake, using the single-optically stimulated luminescence (SIL) method.

TL;DR: In this paper, the authors used optical stimulated luminescence (OSL) to date colluvial and alluvial sediments from a mesoscale catchment in northern Bavaria.

TL;DR: In this paper, the authors focus on the chronological relationship between alternating dune sand and silty water-lain sediments in the central part of the Khongoryn Els dune field in the Gobi Desert, Southern Mongolia.

TL;DR: In this paper, the Alleret maar (Massif Central, France) is part of the few Western European early middle Pleistocene lacustrine sequences, and the authors obtained three 40 Ar/39 Ar ages, which range from 683 −± −5 −ka (MSWD: 1.2, n ǫ=17) to 722 −±−6 −k (MS WD: 3.2, nǫ = 18).

TL;DR: Wang et al. as mentioned in this paper used recuperated OSL (ReOSL) of fine-grained quartz to date the Nihewan Formation and the loess-paleosol sequence evident in the Haojiatai Section.

TL;DR: In this paper, anomalous fading of the infrared stimulated luminescence (IRSL) signal from the polymineral fine-grain and K-feldspar fractions of aeolian sediments from Hungary has been studied.

TL;DR: In this paper, the results of quartz optical dating and 14 C dating of two sites (Boca do Rio and Martinhal) on the Algarve coast (southern Portugal) were presented.

TL;DR: Marine and Environmental Research Centre of Coimbra, Portugal; Centro de Geofisica de Evora, Brazil; Riso DTU, Portugal, as mentioned in this paper.

TL;DR: In this article, a preliminary investigation into the luminescence characteristics and behaviour of Australian quartz from various regions and depositional contexts across southeastern Australia is presented, finding that quartz from this region is generally well suited to the SAR protocol, although individual sample behaviour should nevertheless be assessed to confirm this.

TL;DR: In this article, the performance of the standardised growth curve (SGC) for quartz OSL has been evaluated in the Qaidam Basin of the Qinghai-Tibetan Plateau (QTP) in China.
