This study evaluates the reliability of multigrain and single-grain K-feldspar post-infrared infrared stimulated luminescence (IRSL) (pIRIR) dating applied to palaeoshoreline sediments at Khyargas Nuur, western Mongolia. It specifically focuses on assessing the extent of pIRIR signal bleaching and proposes an improved methodology for dating shoreline sediments where quartz is unsuitable for luminescence dating. Multigrain pIRIR signals measured at 150°C (pIRIR<sub>150</sub>) and 225°C (pIRIR<sub>225</sub>) were used to date Holocene and older samples, respectively. Single-grain pIRIR dating was conducted for the first time in the region to assess bleaching conditions and refine age estimates. Our comprehensive methodological approach was essential for constructing a robust lake level chronology. Single-grain measurements, combined with the application of the minimum age model (MAM), allowed us to identify and correct for incomplete bleaching in several samples. Notably, many of the multigrain aliquots showed no clear signs of poor bleaching in their equivalent dose (<i>D</i><sub>e</sub>) distributions, which would have resulted in significant age overestimation if single-grain data had not been available. Without this approach, the chronology of lake level fluctuations could have been significantly misinterpreted. By addressing this issue, we confidently date the highest lake level at ~129 m above modern lake (a.m.l) to marine isotope stage (MIS) 5 (~89 ka) and a subsequent highstand (~118 m a.m.l) to the Late Glacial (~14 ka). Following this highstand, lake levels declined rapidly (~25 m/ka), reaching ~20 m a.m.l through the Late Glacial to early Holocene transition. During the late Holocene, the palaeolake experienced a gradual regression to ~7 m a.m.l before reaching its current elevation of 1029 m above sea level (a.s.l).</p>","PeriodicalId":16929,"journal":{"name":"Journal of Quaternary Science","volume":"40 6","pages":"1043-1055"},"PeriodicalIF":2.2,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/jqs.3731","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144853708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This cyclicity has been observed to exert a discernible influence on both marine and terrestrial environments (EPICA community members, &lt;span&gt;2004&lt;/span&gt;; Lisiecki and Raymo, &lt;span&gt;2005&lt;/span&gt;). While the marine realm provides quasi-continuous sediment records back into the Tertiary, terrestrial environmental archives are more complex, often fragmentary, and commonly provide evidence of one interglacial only (Hughes et al., &lt;span&gt;2020&lt;/span&gt;). Sequences comprising multiple interglacials in superposition are uncommon, with notable examples including crater lake (de Beaulieu et al., &lt;span&gt;2001&lt;/span&gt;; Rohrmüller et al., &lt;span&gt;2017&lt;/span&gt;; Stebich et al., &lt;span&gt;2020&lt;/span&gt;) and tectonic lake records (Donders et al., &lt;span&gt;2021&lt;/span&gt;). Moreover, the majority of Central European records was analysed with a purely palaeobotanical (pollen) approach and their chronologies are typically based on wiggle matching (cyclostratigraphy), employing the global marine stable isotope stack (LR04) as a reference (Lisiecki and Raymo, &lt;span&gt;2005&lt;/span&gt;). Despite the prevailing consensus that pollen records offer primary regional, rather than local, signals, there is the possibility that they may be incomplete or influenced by site-specific conditions. This potential limitation renders interregional correlation a challenging endeavour. The presence of regional variations in vegetation patterns, in conjunction with the absence of independent dating methodologies, further complicates stratigraphic classifications. These factors give rise to debates and controversial discussions surrounding the nature of Middle Pleistocene environmental variability.&lt;/p&gt;&lt;p&gt;This assertion is particularly pertinent in the context of the discourse surrounding the palynologically defined Holsteinian interglacial in Central Europe. The initial correlation of this interglacial was with marine isotope stage (MIS) 7 (Caspers et al., &lt;span&gt;1995&lt;/span&gt;). However, subsequent studies moved it further back in time, to MIS 9 (Geyh and Müller, &lt;span&gt;2005&lt;/span&gt;; Litt et al., &lt;span&gt;2007&lt;/span&gt;), and finally to MIS 11 (Nitychoruk et al., &lt;span&gt;2006&lt;/span&gt;; Koutsodendris et al., &lt;span&gt;2013&lt;/span&gt;; Lauer et al., &lt;span&gt;2020&lt;/span&gt;; Fernández Arias et al., &lt;span&gt;2023&lt;/span&gt;; Schläfli et al., &lt;span&gt;2023&lt;/span&gt;). However, the temporal position of glacial advances in Central Europe and especially of intervening interglacials (cf., Van Beirendonck and Verbruggen, &lt;span&gt;2025a&lt;/span&gt;) remains a scientific controversy. Furthermore, direct numerical dating of the Holsteinian is yet limited to a very few case studies. Thus, ‘the lesson being that simple, one-to-one, uncritical correlations with terrestrial, and in particular with the marine isotope sequences, hold many potentially serious pitfalls for the unwary’.
