Yunnan in southwest China has been poorly explored in archaeobotany, especially for periods before the Neolithic when gathering was still dominant in plant utilization. Here, we present an archaeobotanical assemblage consisting of fruit and seed remains from the regionally terminal Paleolithic (8740 ± 30 BP) Tangzigou site in western Yunnan. Our taxonomic identification shows that the archaeobotanical assemblage is poor in diversity with only four taxa, i.e., <em>Celtis</em> sp. (hackberry), <em>Prunus persica</em> (wild peach), <em>Vitis</em> sp. (wild grape) and <em>Choerospondias axillaris</em> (Nepal hog plum), which have served as potential food resources to ancient people of the site. However, the full picture of plant exploitation by the Tangzigou people cannot be gained only from the low abundance and diversity of plant remains at the site itself. Based on what is known of the practices of hunter-gatherers today, most fruits and seeds were probably eaten by Tangzigou people during the course of foraging trips, with only a small fraction being carried back to the site for processing and consumption. The fruit stone remains of <em>C. axillaris</em> have been processed with fire accidently or intentionally; the intentional fire-processing was probably for consumption of the seeds inside, which is compatible with the processing of animal foods with fire by the Tangzigou people. Our study brings to light the possible incorporation of plant food resources into the diet of the latest Paleolithic Tangzigou people who are suggested to have lived under a warm subtropical climate. It also enriches our knowledge of the historical use of wild plants by early Holocene humans in southwest China.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"748 ","pages":"Article 109980"},"PeriodicalIF":1.8,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057312","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}

A detailed structural and crystal-chemical study of clay minerals from biomorphoses and the host rock revealed a structural heterogeneity of the mixed-layer minerals. Using the X-ray diffraction pattern modeling method, it has been established that the clay material in the studied samples is represented by two authigenic mixed-layer (glauconite-nontronite) types with a contrasting relationship between the content of different layers and/or their alternation order, but identical structural and crystal-chemical characteristics of the crystallites. It is shown that such formations should be considered a single heterogeneous mixed-layer structure, with the relationship and/or alternation order of different layer types in crystals varying within certain limits. It has been established that the structural and crystal-chemical characteristics of mixed-layer minerals from brown biomorphoses and host rocks are almost indistinguishable, whereas these parameters are significantly different for green biomorphoses. It is assumed that the newly formed clay minerals from host rocks, like their brown analogs, were formed under similar physicochemical conditions. It is also obvious that during the formation of mixed-layer phases, brown biomorphoses were already deprived of the biogenic organic matter, while green biomorphoses retained it in sufficient quantity to change the environmental conditions within themselves in some places.</p>","PeriodicalId":18150,"journal":{"name":"Lithology and Mineral Resources","volume":"60 5","pages":"553 - 571"},"PeriodicalIF":0.9,"publicationDate":"2025-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145050867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifty-five samples representing phosphorite and associated rocks were collected from six outcrops. Three facies are identified: phosphorites, carbonates, and siliciclastics. The mineralogy of the samples was quantified via X-ray diffraction (XRD) as follows: fluorapatite, dolomite, calcite, pyrite, quartz, and smectite species. Atomic absorption spectrophotometry (AAS) permitted the quantification of the major oxides: SiO₂, Al₂O₃, MgO, Fe₂O₃, CaO, K₂O, Na₂O, P₂O₅, and SO₃ as well as F and loss of ignition (LOI). The statistical analysis of these geochemical data revealed three significant controlling factors during and after the deposition of the studied phosphorite and associated rocks. These factors represent the effects of the diagenesis of phosphorites, argillaceous marine rocks, and alumino-silicates in descending order of their relative strength.

Biostratigraphic data show that the age of sediments penetrated by oil wells from 2280 to 3544 m depth ranged from Early Oligocene to Late Oligocene and deposition took place in inner to middle neritic environments. For 7.8 million years, the rate at which sediments accumulated over the under-compacted Akata Formation shales varied between about 144.34 and 301.54 m/Ma. The high rate of sedimentation triggered the formation of a growth fault and the nucleation and growth of other synthetic faults. The growth faults are characterised by rollover anticline and drag folds consisting of footwall anticline and hanging-wall syncline. The footwall anticlines, like the rollover anticlines, offer drilling targets. Despite strata faulting and associated complexities, principles of sequence stratigraphy was used to successfully correlate well logs across the field in both the strike and dip directions. Four third-order depositional sequences, five genetic sequences, and system tracts were identified. Highstand Systems tract (HST) and Transgressive Systems tract (TST) are well preserved in the four depositional sequences, while LSTs are primarily found in Early Oligocene deeper sequences and in downdip wells, but all generally pinch-out in updip direction.

Boron concentration varies from 14 to 550 mg/L, and δ¹¹B values range from +8.3 to +54.7‰ (+21‰ on average). Low δ¹¹B values (~+14‰) were also obtained in two freshwater samples collected from aquifers of Neogene–Quaternary sediments. These data reflect the high heterogeneity of boron isotopic characteristics in waters of various genesis, which are discharged on the Earth’s surface within the Kerch and Taman peninsulas. It is shown that the increase of boron concentration in the mud volcanic waters is provided by the contribution of isotopically light (δ¹¹B ~ +10‰) boron. The inverse relationship between δ¹¹B and δ¹⁸O values in water was found. It indicates common mechanisms of ¹⁰B and ¹⁸O enrichment in the mud volcanic waters. These processes are temperature-dependent. They demonstrate a significant correlation of boron concentrations ([B]) and its isotopic composition (δ¹¹B) with T(Mg-Li)-temperatures in the range from ~40 to 130^oC. Thus, the chemical ([B]) and isotopic (δ¹¹B) variations observed in the studied mud volcanic waters reflect different depths of the formation of water salt composition and, respectively, the different temperature stages of catagenetic transformation of sedimentary strata. The revealed patterns are probably related to the smectite transformation into illite, which takes place in the clayey strata of the Maikop Group and is accompanied by the release of large volumes of dehydration waters with high δ¹⁸O values (up to +14‰).

However, ice-core sulphur records demonstrate that these events were minor as compared to eruptions of much larger magnitude in recent centuries, with severe implications for past society documented in historical records. Biological and chemical evidence of these events can be found in highly resolved varved sediment records. Such records can provide insight into the responses and resilience of lake ecosystems and surrounding catchments following widespread atmospheric perturbations brought about by large volcanic eruptions. In this study we analysed varved sediments spanning the period 1641–1931 CE from Lake Kassjön, a small boreal lake in northern Sweden. We aimed at assessing the potential impacts of the Icelandic eruption of Laki 1783–1784 and the Indonesian eruption of Tambora (1815), based on diatom analysis in combination with organic and inorganic geochemical analyses at sub-decadal resolution. To provide site-specific process understanding, we also assessed the impacts of an intensive ditching operation, which is known to have occurred in 1900–1902 CE. While no significant responses to the eruption of Tambora were identified, our findings indicate enhanced weathering of minerals in the catchment following the eruption of Laki and changes in nutrient dynamics reflected by multiple decades of succession in the diatom assemblage. In timing with Laki, we found an immediate and sustained increase in the concentrations of <em>Aulacoseira tenella</em>. Increased delivery of terrestrial organic matter to the lake and altered nutrient dynamics persisted for around half a century following the eruption of Laki, coinciding with elevated diatom productivity.
