Electron spin resonance (ESR) dating of optically bleached quartz grains was performed on three sediment samples collected from the Middle Palaeolithic site of Cuesta de la Bajada (Spain). Our understanding of the chronological sequence of Pleistocene land mammal faunas (including hominids) preserved in caves and fissures in the karstic terrain of subtropical southern China has been greatly...The establishment of standardised growth curve (SGC) for equivalent dose (De) determination can substantially reduce the amount of instrument time required for OSL measurements. OSL and IRSL dating are applied to samples from a 152 m-long drill core to constrain the timing of three glaciolacustrine depositional periods within the infill of an overdeepened bedrock trough in... Rapagnã | Katerina Douka | Edson Silva The mixture of different water masses can strongly influence the marine reservoir effect (MRE) in localities under the effect of coastal marine upwelling. Baldini Robust chronologies are crucial for the correct interpretation of climate proxy records and for detailed reconstructions of palaeoclimate.This study assesses whether internal U, Th and Rb concentrations of single grains of alkali-feldspar can impact upon luminescence dating. The Cabo Frio region, on the southeastern Brazilian... Lechleitner | Jens Fohlmeister | Cameron Mc Intyre | Lisa M. Jamieson | Helena Hercman | Michał Gąsiorowski | Jacek Pawlak | Krzysztof Stefaniak | Paweł Socha | Timothy I. Stalagmites have garnered strong interest as recorders of past...Prices in GBP apply to orders placed in Great Britain only. I present measured quartz single grain OSL sensitivity distributions for an aeolian dune sample from the Simpson Desert, Northern Territory, Australia, and from a suite of 9 fluvial sediments from Namadgi National Park, Australian Capital Territory, Australia, to illustrate effects that result from natural differences.Prices in € represent the retail prices valid in Germany (unless otherwise indicated). Minimum age model determinations of synthetic DHere you can find all Crossref-listed publications in which this article is cited.During the past two decades, reverse-phase (RP) liquid chromatography... The uppermost 50 cm of sediments from the 23 m deep lacustrine basin of Nurmijärvi, a lake in south-central Finland, are composed of the clastic-biogenic type of varves. A 5 mm thick tephra layer has been identified in the lacustrine sediments of Moon Lake in the Arxan-Chaihe volcanic field (ACVF) in Greater Khingan Mountains (NE China). Numerous volcanoes in the Afar Triangle and adjacent Ethiopian Rift Valley have erupted during the Quaternary, depositing volcanic ash (tephra) horizons that have provided crucial chronology for archaeological...In the note “A response to some unwarranted criticisms of single-grain dating” Feathers raises many issues with both the approach and the conclusions of Thomsen et al. We have applied the unspiked K-Ar and the 40Ar/39Ar methods to samples precisely collected and localised, on both Central Indian Ridge flanks, to test their effectiveness and reliability when applied...

The Cosmic-Ray Produced Nuclide Systematics on Earth Project (CRONUS-Earth Project) has reused a limited number of ‘legacy’ 10Be, 26Al, and 36Cl samples of latest Pleistocene age for the assessment...

The Cosmic-Ray pr Oduced NUclide Systematics on Earth Project (CRONUS-Earth Project) has reused a limited number of ‘legacy’ 10Be and 36Cl samples from late Pleistocene moraines in the Sierra Nevada...
