In such contexts, quartz can have unstable and weak signals, feldspar have less bleachable and fading signals and both require statistical modelling to extract the true burial age data. This paper presents a new approach using feldspars measured at multiple elevated temperatures (MET) and screened to select grains with plateau equivalent dose values which should be the well-bleached and unfaded grains upon which to base a true burial age. The MET plateau approach was tested on an aeolian site in Canada and two former UK glacial sites. When applied to the Canadian aeolian samples, it showed that the method successfully accepted mostly well-bleached grains whilst excluding grains with fading or that had poor luminescence characteristics. When applied to a well dated glacial sequence it yielded ages in good agreement with existing independent chronologies. A previously undated glacial site yielded stratigraphically consistent ages but these are thought likely to be slight age over-estimates due to extremely limited bleaching at deposition. In summary, the MET plateau approach improved avoidance of partially bleached grains, avoided corrections for residuals and/or fading and reduced the need for statistical models to interpret equivalent dose distributions. However, some glacial sediments may have had so limited bleaching that these may still not be easy to luminescence date. The MET plateau approach if adopted could allow re-evaluation of existing glacial chronologies and extend luminescence dating to more glacial sediments.</div></div>","PeriodicalId":54516,"journal":{"name":"Quaternary Geochronology","volume":"87 ","pages":"Article 101659"},"PeriodicalIF":1.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While luminescence dating is among the most commonly used approaches, incomplete resetting of the signal before sediment deposition makes its application to such deposits challenging. Single grain (SG) and cobble luminescence dating have been used to account for heterogeneous bleaching with different success, and are tested here in combination on glaciofluvial deposits from one site in the northern Alpine foreland. Previous chronological investigations indicate that deposition of the proglacial outwash occurred ca. 29 ka ago. SG feldspar results on sand lens and gravel sandy matrix samples underestimate the previous age estimates due to the occurrence of grains with low equivalent dose (D_e) values. When low D_e values are discarded, the estimated ages are in agreement with the independent constraints. Luminescence-depth profiles obtained from four cobbles show (1) no or only shallow bleaching, and (2) high variability between cores and surfaces of the same clast. Both aspects highlight the necessity of measuring numerous clasts and several cores in order to detect well-bleached clasts and profiles. The limited signal resetting can be explained by the proximity of the deposit to the glacial front. The intra-cobble variability is instead potentially related to heterogeneity in the cobbles’ lithology, implying differences in dosimetry, signal stability and light attenuation within the clasts. Electron microprobe analyses of feldspar in the clasts and comparison with the independent age constraints suggest that (1) the luminescence signal of the rock slices derive from both Na- and K-rich feldspars and (2) an average internal potassium content may be a good first order estimate for dose rate calculations.

To determine the impact date and impact-driven old carbon effects on radiocarbon cycles recorded in post-impact lake sediments, we performed radiocarbon (¹⁴C) dating of various organic fractions (humic acids, humins, charcoal, and organic plant fragments of various sizes) in post-impact lake sediments of the Hapcheon impact crater, Korea. Charcoal and plant fragments larger than 500 μm in the post-impact lake sediments of core 20CR09 constituted the oldest fraction (&gt;45,000 cal BP), indicating pre-impact ages. Compared to micro-organic fragments (10–100 μm) consisting of terrestrial plant tissues, pollen, and limited freshwater algae with a narrow age range of 39,300–42,300 cal BP, the 100–500-μm plant fragments showed a slightly older age range of 41,670–43,910 cal BP throughout the 33-m-long lake sediment core. This suggests significant influence of well-mixed syn-impact organic fragments transported from slope deposits consisting of impact breccias and fallback deposits. Humin ages in the lake sediment of core 20CR05 were similar to those of the micro-plant fragments in core 20CR09, indicating that the humin fraction is mainly allochthonous. Humic acids at a depth of ca. 71 m, corresponding to the lowermost post-impact lake sediments (Stage 1), were dated to ∼21,000 cal BP, showing strong influence of post-impact humic acids ages. Whereas those from mid-depth lake sediments (Stage 2) were dated to 35,000–43,000 cal BP. This age reversal indicates increased input of syn-impact allochthonous humic acids, supported by positive correlation with terrestrial mineral input. This study demonstrated significant syn-impact radiocarbon effects and resultant age reversals in post-impact early lake sediments. The syn-impact age may be estimated by comparing ages of different-sized plant fragments (e.g., 10–100, 100–500, and &gt;500 μm), humin, and humic acids. These findings suggest that climatic and environmental interpretations of these post-impact early lake sediments should be conducted only after testing various organic materials, if radiocarbon dating is applied. Lastly, compared to surrounding areas following natural climate changes, post-impact early lake environments in impact craters must be considered as anomalies with different ecosystems due to hydrothermal activity.</div></div>","PeriodicalId":54516,"journal":{"name":"Quaternary Geochronology","volume":"86 ","pages":"Article 101649"},"PeriodicalIF":1.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143167775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, detailed chronological studies are lacking. This study investigates the applicability of the MAR MET-pIRIR protocol to the Danba (DB) loess-paleosol sequence in the eastern TP, aiming to establish a chronological framework for this typical loess sequence. For TP loess samples with equivalent doses (D_e) below ∼950 Gy, multi-aliquot MET-pIRIR₂₅₀ and single-aliquot pIR₂₀₀IR₂₉₀ dating methods yield consistent results.

Using MAR MET-pIRIR protocol with the global standard growth curve method, we have established a new absolute chronological framework for the DB loess-paleosol sequence, indicating that loess deposition in the TP began at least ∼230 ka ago.

Six tephra layers were identified in six replicate short peat cores at Bankhead Moss, a raised bog in Fife, eastern lowland Scotland. Geochemical and stratigraphic correlations indicate that the tephras originate from Icelandic and Alaskan sources. We make firm correlations to Askja 1875 and WRAe, a broad correlation to Mount Churchill with the possibility of Lena tephra being inferred from its estimated timing, and uncertain correlations of three tephra layers of Icelandic origin, considering the mixed nature of these three tephra layers under the potential influence from post-depositional reworking and multiple volcanic sources, e.g. Hekla, Öræfajökull and Katla. This is the first secure record of the Askja 1875 tephra in the British Isles, which significantly extends its known spatial distribution and suggests a more complex dispersal pattern of this tephra than previously thought. Persistent presence of shards throughout parts of the peat sequences may reflect post-depositional movement of tephra shards within the peat, reworking from surrounding landscape, and/or sparse fallout from other eruptions. Our records indicate that any single peat core from this site gives a good approximation of the overall tephrostratigraphy, but there is considerable spatial variation in tephra concentrations between cores. Age-depth models for the six cores based on cryptotephras, spheroidal carbonaceous particle (SCP) counts, and radiocarbon dates likewise vary between cores, showing a pattern consistent with peat accumulation in a domed raised bog.

To investigate this phenomenon, a series of samples were analyzed from two sections at Ximachi in Heqing County, China, which have strong Ti–H signals. The sample ages were obtained using the electron spin resonance (ESR) multiple-centers approach, and the reliability of the ages was validated by comparison with optically simulated luminescence (OSL) ages and between different paramagnetic centers. The ESR data demonstrate that the Ti–H centers can provide accurate dose estimates up to 750–950 Gy, with varying degrees of underestimation at high doses. Combined with previously published Ti–H data, it is evident that the upper threshold of the accurate data obtained from Ti–H centers depends on the sample, and may be positively correlated with the Ti–H/(Ti–Li + Ti–H) ratio (option C/D). According to the provenance significance of the Ti–H/(Ti–Li + Ti–H) ratio, we propose that the Ximachi samples have high Ti–H/(Ti–Li + Ti–H) ratios and then equivalent dose saturation values of Ti–H centers, which may be related to the thermal history of the analyzed quartz grains.</div></div>","PeriodicalId":54516,"journal":{"name":"Quaternary Geochronology","volume":"85 ","pages":"Article 101635"},"PeriodicalIF":1.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a previous study, infinite infrared stimulated luminescence (IRSL) ages have been determined for the lower part of the core using a multi-grain approach. Applying single-grain feldspar luminescence dating allows to identify the unsaturated signals, previously masked by multi-grain signal averaging. Identification of the normally distributed leading edge in equivalent dose (D_e) distributions allows for the dismissal of low value D_e (LOVED) grains that appear to reflect underestimating outliers. Measurement of eleven samples distributed along the entire length of the core yielded two distinct age clusters, for which fading corrected IRSL₅₀ and uncorrected pIRIR₂₂₅ ages agree within uncertainties. Whereas the younger age cluster at the top of the sequence is attributed to Marine Isotope Stage (MIS) 3, the older age cluster is assigned to MIS 6. It is shown that single grain pIRIR measurements will allow to resolve the infill chronology of overdeepened structures in the Alps, at least for the last ca. 200 ka.
