Due to the slow uplift of the crust since the Neogene and extensive river downcutting that made these caves accessible, the sediments in these karst caves preserve a plethora of Quaternary vertebrate fossils (including hominins) and occasionally stone artifacts. These remains provide important clues for studying the paleontology, archaeology and paleoenvironment in the region. However, in these caves it is difficult to understand how these fossils were deposited. In fact, it is often extremely difficult to determine the provenance and transport history of homogeneous clastic sediments, which may carry these fossils and artifacts into these caves, because they often do not have distinct sedimentological features. Here we present a provenance analysis of the Pleistocene clastic sediments from Chuifeng, Mohui, Ganxian and Luna Caves, four caves that may be considered representative of the basin, and compared with the sediment samples from the local fluvial terraces and the surface of limestone hills in Bubing Basin, Guangxi, southern China, utilizing their major and trace element composition as a provenance marker. The major, trace element ratios, and rare earth element distribution data all indicate that the clastic sediments of these four cave sites are directly derived from the weathered residual sediments found on the limestone hills where these caves are located. In all cases, the cave deposits are clearly different from the clastic sediments from the four local fluvial terraces in the basin. Our results provide a new set of data that complement and further expands the common view that these clastic sediments and encased mammal fossils are transported into these cave sites by fluvial action. The clastic sediments on these limestone hills are primarily transported into the caves through cave entrances and/or pipeline or fractures in the hills by sheet flow. As such, it is likely that biological agents (e.g., porcupine and/or carnivore/hominin transport) and not fluvial activity may have played an even greater role in the accumulation of vertebrate fossils in cave sites than traditionally thought. This study should have broader implications in investigations into the relationship between clastic sediments and fossils in cave sites across time and space.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"714 ","pages":"Article 109580"},"PeriodicalIF":1.9,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759038","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}

It is of Neolithic Age and dates from approximately 7000 to 5000 years ago. A large number of animal skeleton fossils have been unearthed at the site, many of which, especially those belonging to species of Cervidae (possibly Sika, <em>Cervis nippon</em>), are characterized by the presence of black residue on the surface. There are three types of residue, one is black film-like coating, which is suggestive of exposure to fire, one is also black, but crystalline in nature, while the other is grey-white, particulate deposit. With the aim of exploring the nature of these residues and their possible origins, we applied a number of analytical techniques, including Raman Spectroscopy (RS), Fourier Transform Infrared Spectroscopy (FTIR), Energy dispersive spectroscopy (EDS) and Electron Microscopy (EM) on six bone fossils belonging to different parts of Cervidae skeleton unearthed from Luotuodun to evaluate the possible influence of fire and/or depositional processes in their formation. The black film-like coating, widespread on the surface of these bones, is highly reflective and appears white under the Raman microscope. The RS peak indicates that the film-like substance is rich in carbonaceous (graphitic carbon) components, suggesting that the bones have been exposed to combustion. FTIR measurements on these bones show that the structure of hydroxyapatite carbonate (Ca₁₀(PO₄)_6−x(CO₃)_x(OH)₂) has changed, consistent with their exposure to very high temperatures (500–600 °C), and implying that they were burnt, either for cooking or ritual behavior by ancient humans. In the case of the crystallized black particles, these are primarily confined to localities on the surface of bone fractures. EDS results, as confirmed by the RS analysis, show that the black crystals are comprised of an iron-rich, phosphatic mineral, compatible with vivianite (Fe₃(PO₄)₂·(H₂O)₈). The substantial vivianite content is consistent with the fossil bones being submerged and deposited in waterlogged soils. The results of EDS show that the composition of the grey-white particle is hydroxyapatite carbonate (Ca₁₀(PO₄)_6−x(CO₃)_x(OH)₂). Non-destructive geochemical analysis of the surface residues of these Luotuodan bones provides valuable evidence for reconstructing the taphonomy of the Cervidae bones, and reveals that they were utilized by ancient humans during the Luotuodun culture period in SE China.</div></div>","PeriodicalId":49644,"journal":{"name":"Quaternary International","volume":"713 ","pages":"Article 109574"},"PeriodicalIF":1.9,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142759443","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}
