The loess deposits in northern Iran are situated in the transitional zone between the European loess and Central Asian loess. However, the depositional dynamics and paleoenvironmental significance of the loess deposits in this region are not well understood, making it difficult to establish detailed correlations with loess deposits elsewhere, partly due to the lack of systematic and high-resolution chronological control. We used K-feldspar pIR₅₀IR₂₉₀ and MET-pIRIR₂₅₀ luminescence dating protocols to date fifty-two K-feldspar samples from the Toshan-19 section in the northern foothills of the Alborz Mountains, northern Iran. These chronological data, along with the climate proxies of magnetic susceptibility and redness, combined with a comparison with published loess records from various regions, indicate the following: (1) K-feldspar luminescence ages obtained using pIRIR and MET-pIRIR protocols are consistent, and their luminescence ages up to ∼200 ka are deemed dependable. The loess at Toshan was primarily deposited during 78–24 ka, corresponding to MIS 4–2, and the paleosols developed during 139–78, and 24–1.7 ka, corresponding respectively to MIS 5, and late MIS 2–MIS 1. (2) Drier conditions prevailed during the last glacial and wetter conditions dominated during the last interglacial. Moisture variations during the substages of MIS 5 in this region indicate cold-dry and warm-wet climatic characteristics. The reasons for increased moisture from late MIS 2 onwards in this region still require further investigation. (3) The loess-paleosol records indicate a consistent pattern of climate change over Eurasia on the scale of the last interglacial-glacial cycle. During the substages of MIS 5, warm-wet and cold-dry conditions in northern Iran were in-phase with those on the Chinese Loess Plateau, Europe, and southern Tajikistan; however, they were anti-phased or out-of-phase with those in Xinjiang.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"354 ","pages":"Article 109213"},"PeriodicalIF":3.2,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143395032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used principal component analysis to extract the past 50 years of ASM variation and summer precipitation tripolar spatial pattern from 10 δ¹⁸Oc records.

However, precipitation variation patterns and driving factors in southwestern China differ from those in eastern China, suggesting that the spatial distribution of precipitation in Chinese monsoon region is highly complex.

Determining the ecological and evolutionary history of megafaunal communities requires a detailed study of chronology, climate change, environment, and human impact. While some regions of North America are well-studied in this regard, others, such as Mexico, have been more neglected. This is despite the fact that, by the end of the Pleistocene, the region had witnessed the extinction of fourteen families (Chlamyphoridae, Megalonychidae, Mylodontidae, Felidae, Canidae, Ursidae, Tapiridae, Antilocapridae, Bovidae, Cervidae, Gomphotheriidae, Mammutidae, Toxodontidae, Macrauchenidae) and the regional extirpation of a further four (Equidae, Camelidae, Elephantidae and Megatheriidae). Moreover, this region is located at a biotic crossroads and has yielded some of the earliest dates for human occupation across the Americas. This makes Mexico an important study region to explore the effects of human presence and climate change on a variety of megafaunal species. However, research has been hindered by an uneven balance of research, preservation issues, lack of chronological control, and limited synthesis of the available data. In this paper, we provide a critical review of the available records of Late Pleistocene megafauna in Mexico and their relationship to human populations. We evaluate the quality of dates and stratigraphic contexts of recorded megafauna on a site-by-site basis while also exploring available information on human presence and impact on megafauna. We highlight that currently, the human impact on the decline of these populations is far from clear and that more multidisciplinary excavations of well-dated sites are needed. Nevertheless, we contend that current evidence suggests that human hunting of megafauna occurred across most of the Mexican territory in a variety of habitats, with some evidence in the south that these hunts were complemented by significant acquisition of small game, aquatic species and plant foods.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"353 ","pages":"Article 109200"},"PeriodicalIF":3.2,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143386984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In comparison with the loess sequence, the Red Clay sequence has lower dust accumulation rate, older depositional ages and was deposited in a warmer climate. These factors result in stronger degree of mineral oxidation, lower content of fine ferrimagnetic minerals and higher content of hematite. Therefore, magnetic parameters widely used in the loess sequence, such as magnetic susceptibility, may not be as effective in indicating past precipitation in the Red Clay sequence. It is notoriously well known that Red Clay lacks precessional cycles, the most obvious period dominating summer insolation. Here we explore the potential of “hard’’ isothermal remanent magnetization (HIRM), a parameter estimating hematite content, in recording past climatic changes in the Red Clay sequence. In contrast with the magnetic susceptibility record which only shows prominent 1 Myr and eccentricity cycles, the HIRM record shows all orbital and their harmonic cycles. Intriguingly, we also detected multiple millennial cycles from HIRM and found the amplitude variations of multiple millennial cycles are controlled by precession, obliquity, and their amplitude modulators. This work extends detecting of precession and multiple millennial cycles from the CLP deposits back to the late Miocene for the first time and revolutionize our thinking regarding how East Asian summer monsoons varied based on the CLP records for the late Miocene-Pliocene interval.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"353 ","pages":"Article 109223"},"PeriodicalIF":3.2,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143349209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Site chronological models reveal sharp fluctuations in the overall level of recorded Mesolithic activity. A spike in the intensity and diversity of activity coincided with the rapid expansion of hazel (<em>Corylus avellana</em>) at the start of the Boreal biozone, but a steep decline in dated activity in the later 9th millennium BCE may be an artefact of changes in lake level, rather than reflecting a response to vegetation change, climate deterioration or societal reconfiguration. Although the Duvensee radiocarbon results can be construed to support arguments that rapid climate change had a significant impact on human activity, known climate events occurred when the record of human occupation at Duvensee was already discontinuous. It is therefore difficult to infer (or exclude) environmental factors as triggers of changes in the archaeological record.

Here we present a well-dated, high-resolution, quantitative temperature reconstruction based on a branched glycerol dialkyl glycerol tetraether (brGDGT) proxy for the last ∼5000 years from a high-elevation peatland in southwestern China. Our record reveals a general warming trend during the mid-to-late Holocene.

To better understand the pattern of mid-to-late Holocene temperature changes from existing paleoclimate records in southwestern China, we further compiled and analyzed 19 high-quality quantitative paleotemperature records in this region and the nearby Tibetan Plateau. The results reveal that temperature records from high-elevation sites (&gt;3000 m above sea level) generally display an overall warming trend, whereas temperature records from low-elevation sites (&lt;3000 m above sea level) generally show an overall cooling trend. We speculate that the reconstructed temperature records from low-elevation areas might be affected by human activities. In addition, we analyzed 9 records from a sub-region of southwestern China with adequate temporal-resolution and chronological controls to evaluate multicentennial-scale fluctuations over the past millennium. We find that most records show pronounced shifts during the MWP and LIA.
