TL;DR: In this paper, the authors present a holistic tephra stratigraphy and chronology based on detailed analysis of major element chemistry generated from four lakes located on northeastern Vestfirðir.

TL;DR: In this article, optically stimulated luminescence (OSL) and cosmogenic radionuclide 10Be (CRN) were used to date terraces along the NE Pamir margin.

TL;DR: In this article, the authors compared different counting methods to count biogenic varves in Lake Żabinskie in northeastern Poland and found possible disadvantages in arbitrary assumptions and subjective decisions in the process of chronology building, procedures leading to age underestimation and problems with reliable and objective estimations of counting uncertainty.

TL;DR: The Shirasuka lowlands, located on the Enshu-nada coast of central Japan, record evidence for numerous extreme wave events as mentioned in this paper, and the applicability of using the luminescence signal from feldspars to date these young (

TL;DR: In this article, the authors study alluvium-filled horizontal epiphreatic passages in limestone karstic networks to increase the span of this dataset and reconstruct a more complete valley incision chronology.

TL;DR: In this article, an inverse modelling approach for fine-grained quartz OSL ages of loess deposits is proposed to generate a probability density function of the random uncertainty part and use this function to recalculate and improve stratigraphically related OSL dates.

TL;DR: The issue of comparability of measurements (and thus bias, accuracy and precision of measurement) from the diverse laboratories is one that has been the focus of considerable attention for some time, both within the 14C community and the wider user communities as discussed by the authors.

TL;DR: In this paper, high resolution 14C AMS ages from sequential layers in the late Quaternary Dilpur Formation in Indian Kashmir, reveal glacial and interglacial climatic changes archived in this more or less complete aeolian-palaeosol record.

TL;DR: In this article, a low-temperature post infrared infrared stimulated luminescence protocol (pIRIR150) was used to evaluate the potential of single grain feldspar luminecence dating applied to late Holocene cyclone and tsunami deposits, for which complete signal resetting can a priori not be guaranteed.

TL;DR: In this article, variations in the chronometers and individual site histories from six ombrotrophic peat bogs in central and northern Alberta were investigated and then integrated using OxCal's P_Sequence function to produce a single Bayesian age model.

TL;DR: In this paper, the Schmidt Hammer exposure dating (SHED) method is used to date glacial landforms in the UK using a set of N-type Schmidt Hammers.

TL;DR: In this article, a global standardised growth curve (gSGC) was constructed from the post-infrared infrared stimulated luminescence (pIRIR) signals emitted by individual grains.

TL;DR: Petchey et al. as discussed by the authors further developed a tri-isotope approach using 14C, δ13C, and δ18O to identify carbon source.

TL;DR: In this article, a more robust chronology of the Danube valley in Hungary, new cosmogenic nuclide- (10Be depth profiles, 26Al/10Be burial durations and burial depth profile) and luminescence-based (pIRIR290) terrace ages were acquired and compared to revised paleontological and published U/Th and magnetostratigraphic data.

TL;DR: In this paper, the single-aliquot regenerative-dose (SAR) multi-elevated-temperature post-IR IRSL (MET-pIRIR) dating protocol with a large number of samples from various backgrounds was performed on potassium feldspar.

TL;DR: In this article, a precisely 230Th-dated stalagmite oxygen isotope (δ18O) record from Dragon Cave,Shanxi Province, northern China, is proposed to reconstruct the millennial-scale changes of the East Asian Summer monsoon (EASM) during the period 53.2-1.3 ka BP (before 1950 AD).

TL;DR: In this paper, the authors show that when a Bayesian chronological model is used, which incorporates an Outlier Model specific to wood charcoal, the 14C dataset of Iceland's Viking Age settlement agrees well with ice core-dated tephrochronology and written sources.

TL;DR: In this article, negative magnetic polarity directions for these stratigraphic levels, a result consistent with previous studies that already identified the Matuyama-Brunhes boundary between TD7 and TD8 levels, were obtained, and the combination of ESR, luminescence, biostratigraphy, with new paleomagnetic results, supported a post-Jaramillo age for layer TD4 in Gran Dolina.

TL;DR: In this article, an alternative approach based on the combination of in situ-produced 36Cl based cosmic ray exposure dating, lichenometry and dendrochronology was tested on two lava flows (called Lava flow "A" and “B”) from Pico de Orizaba (Mexico), previously attributed to 16th and 17th century eruptions, respectively.

TL;DR: In this paper, the authors presented the tephrochronological findings from Crudale Meadow, Orkney, one of the most northerly former marl lakes in the British Isles.

TL;DR: In this paper, optically stimulated luminescence (OSL) on quartz, IR-RF on K-feldspar were applied in conjunction with multiple-centres electron spin resonance (ESR) dating on quartz.

TL;DR: In this article, the authors conducted inter-laboratory AMS 14C dating of bones of the Miesenheim IV elk (Rhineland, Germany), buried under Laacher See tephra dated to ca. 11,060 BP (13,000 cal BP).

TL;DR: Wang et al. as discussed by the authors applied coupled ESR/U-series dating method on Bailongdong hominin cave site in Hubei Province, central China, which is a key area to study early human migration between South and North China.

TL;DR: In this paper, the authors examined two samples from the site of MacCauley's Beach, NSW, Australia that were considered to be influenced by BM but not quantifiably demonstrated.

TL;DR: The inter and intra-crystalline fractions of the topshell Phorcus lineatus recovered from modern specimens and shells from archaeological sites in Northern Spain covering Neolithic, Mesolithic, and Upper Magdalenian periods were examined for amino acid composition and racemisation over time as discussed by the authors.
