Water-rock interaction (WRI) and prior calcite precipitation (PCP) are two mechanisms mostly used to interpret trace elements in speleothems. It is usually assumed that higher ratios of trace element to calcium (X/Ca) indicate enhanced WRI and/or PCP effects and in turn drier climates. In this study, the Mg/Ca, Sr/Ca, Ba/Ca, and ⁸⁷Sr/⁸⁶Sr ratios of stalagmite KY1 (collected from Kaiyuan Cave in Shandong Peninsula, coastal North China) were determined and the mechanisms dominating the X/Ca and ⁸⁷Sr/⁸⁶Sr ratios were investigated. The results indicate that 1) the soil layer overlying Kaiyuan Cave is an important source of trace elements in stalagmite KY1, contributing more than a half of Sr in stalagmite KY1; and 2) chemical weathering of the soil layer, instead of the two widely used mechanisms WRI and PCP, dominates the variations of the Mg/Ca, Sr/Ca, and Ba/Ca ratios in stalagmite KY1 during the last millennium. Before ∼1670 CE, chemical weathering of and trace element release from the soil layer were controlled naturally by climates. Warm-humid climates strengthened chemical weathering of the soil layer, releasing relatively more trace elements and eventually resulted in higher X/Ca ratios in stalagmite KY1. Cold-dry climates were responsible for lower X/Ca ratios. After ∼1670 CE, human activities played a key role on the X/Ca ratio variations in stalagmite KY1. Enhanced reclamation led possibly to deforestation, reduced residence time of groundwaters in the soil layer, weakened chemical weathering of the soil layer, resulting in lower X/Ca ratios in stalagmite KY1. This study underlines the importance of the soil layer to accurately interpret trace elements in speleothems.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"736 ","pages":"Article 109847"},"PeriodicalIF":1.9,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lake shore was a fluvial-lacustrine landscape shaped by seasonal and long-term transgressions and regressions. However, the basis for linking sedimentary environments to paleolandscapes and pre-Hispanic settlements dynamics is lacking. Thus, we focus in this study on reconstructing sedimentary environments using geochemical and sedimentary facies analyses to study the paleolandscape inhabited by agricultural societies in the Lake Texcoco region. To test this approach, we studied the interface between the San Bernardino and Chapingo Rivers with the lacustrine realm on the eastern shore of Lake Texcoco. We defined sedimentary facies by analyzing their macro and microscopic attributes, as well as using XRD, p-ED-XRF, TOC, C/N, and texture analyses to assess their chemical, mineralogical, and sedimentological characteristics. The combined results allow eleven facies to be assigned to three distinct environments, i.e., lacustrine, transitional fluvial-lacustrine, and fluvial settings. The stratigraphic sections showed a lake transgression with a minimum age of 1293–1242 cal yr BP (657–708 CE) and 1363-1294 cal yr BP (587–656 CE). The absence of archaeological sites in the lower plains during the Late Classic period supports the interpretations of the lake phase. At least two regression phases are interpreted. The first event occurred during the Epiclassic period with a minimum age of 1154–1051 cal yr BP (796–899 CE). The second event has a minimum age of 560–518 cal yr BP (1390–1432 CE), which is consistent with the rise of multiple settlements during the Late Postclassic period. This interpretation is further supported by the increase in settlements during the Postclassic period, probably related to an increase in the variety of natural resources available.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"735 ","pages":"Article 109840"},"PeriodicalIF":1.9,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144134676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relative scarcity of archaeological and chronological references in African rainforests further complicates their integration into a broader evolutionary framework. Since 2014, 11 archaeo-paleontological campaigns have been conducted in Equatorial Guinea to uncover evidence of early human settlements in West Central Africa. These surveys identified 449 Quaternary outcrops, 50 of which yielded Paleolithic stone tools. Technological analysis reveals recurring patterns in Equatorial Guinea, particularly the widespread use of centripetal flaking techniques, either bifacial or unifacial, for flake production. Other methods include blade production and bipolar-on-anvil flaking. Retouched tools are characterized by large cutting and heavy-duty tools, such as handaxes, cleavers, and wedges, alongside bifacial points. Retouched flakes, including scrapers and denticulates, are rare, but some backed elements were identified despite their scarcity. A clear distinction emerges between coastal and inland sites. Coastal sites show greater raw material diversity and Acheulean-like morphotypes, absent in inland regions. The origins of these differences remain uncertain but may reflect geological, functional, ecological, or population history factors. The assemblages share features with the Middle Stone Age (MSA), including bifacial points, prepared core technologies, and laminar knapping. Acheulean morphotypes and heavy-duty tools, typical of the final phases of Mode 2, coexist with MSA characteristics, aligning the industries with the Lupemban technocomplex. This technocomplex appears to aggregate Mode 2 morphotypes, such as handaxes and cleavers, and Mode 3 flake production techniques and morphotypes, potentially indicating a degree of cultural continuity over at least 250 ka. However, preliminary dating places these industries within the Upper Pleistocene, with geological evidence suggesting poor preservation of sedimentary records predating the last glacial cycle.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"736 ","pages":"Article 109849"},"PeriodicalIF":1.9,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144131003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate the dietary conditions of the early Yangshao ancestors in this area, analysis of plant micro-remains (starch grains and phytoliths) and organic acid residues was conducted on 34 pottery samples unearthed at the Chengyan Site in Lingbao City, western Henan Province, central China. The results revealed that the plant foods of the Chengyan people included Triticeae, Job's tears (<em>Coix lacryma-jobi</em>), rice (<em>Oryza sativa</em>), millet (<em>Setaria italica</em> and <em>Panicum miliaceum</em>), lotus root <em>(Nelumbo nucifera</em>), snake gourd root (<em>Trichosanthes kirilowii</em>), yam (<em>Dioscorea</em>), lily (<em>Lilium brownii</em>), legumes (Fabaceae), and acorn (<em>Quercus</em>), in which, some species served as raw materials for brewing fermented beverages. These findings demonstrate that botanical resource exploitation during this period in central China exhibited remarkable diversity, with foraging maintaining its significance as an essential subsistence strategy for early human populations in acquiring plant foods. The presence of rice at the Chengyan site indicates its spread to western Henan during the early Yangshao period, and a rice-millet mixed farming, dominated by foxtail millet and broomcorn millet, had developed in the area.

The stratigraphic record from the Punta de s'Avançada outcrop in North Mallorca provides valuable insights into the paleoenvironmental changes driven by Heinrich (HE) and Dansgaard-Oeschger (DO) events during the late Pleistocene. Detailed analysis of six distinct sedimentary units (U1-U6) reveals the significant impact of abrupt climatic shifts on sediment supply, depositional environments, and sea-level fluctuations. The cold, arid conditions during HE events, particularly H4 and H5, promoted extensive dune formation in Units U4 and U6, while the warmer, wetter conditions during DO events facilitated alluvial and colluvial deposition in Units U1 and U5. By integrating OSL dating with climatic oscillations, this study demonstrates the influence of millennial-scale HE and DO events on sedimentary processes in coastal landscapes of the western Mediterranean.
