Significance Human evolution through the Middle to Late Pleistocene in East Asia has been seen as reflecting diverse groups and discontinuities vs. a continuity of form an evolving population. New (∼300,000 y old) human remains from Hualongdong (HLD), China, provide further evidence for regional variation biology Asian archaic humans. The HLD 6 skull is notable its low wide neurocranial vault pronounced brow ridge, but less projecting face modest chin. Along with isolated teeth, provides...
Based on stable hydrogen and oxygen isotope data (δ18O, δD) meteorological observation for complete hydrological annual precipitation from 2016 to 2017 in the monsoon marginal region of northern China (Fengxiang Ningwu), isotopic characteristics sources water vapor these two regions combined were studied. The results showed that δ18O δD values wet season (June through September) higher than dry (October May following year) Fengxiang Ningwu. intercept slope meteoric line somewhat low,...
The response of trees to climate is crucial for the health assessment and protection forests in alpine regions. Based on samples Pinus tabuliformis Abies fargesii, two typical evergreen coniferous species with distinct elevation differences vertical vegetation zones Qinling Mountains, we have developed tree-ring width chronologies southern slope central Mountains China. correlation analysis results showed that radial growth P. A. fargesii responded different climatic factors. Water stress...
The Qinling Mountains in central China are rich polymetallic mineralizations (e.g., Pb-Zn-Au deposits), and historic mining has resulted large amounts of heavy metals being released into the environment. Thus, it is important to evaluate ecological risk triggered by at this location. In work, a gold mine was investigated as case study better understand health risks present Mountains. To address issue, total 84 soil samples 23 surface water were collected from district. Major trace elements...
Abstract Understanding regional hydroclimate and its driving mechanisms is important for accurate projections of hydrology variations in the future. This study provides a record over past 5.7 ka based on speleothem climatic proxies from Jiuxian cave, central China. Our suggests that coupling between sea surface temperatures (SST) Indo‐Pacific warm pool (IPWP) positioning Western Pacific Subtropical High (WPSH) modulate both spatial heterogeneity hydrological conditions millennial‐centennial...
Abstract As a highly volatile heavy metal, Hg is transported over long distances in the atmosphere and enters global ecosystems via Hg(II) wet deposition Hg(0) dry deposition. The Chinese Loess Plateau develops loess‐paleosol sequences (eolian deposits) reflecting glacial‐interglacial cycles. Here, we investigate concentration isotopic composition of covering three cycles (spanning 350–80 ka). Paleosol layers display higher THg, Δ 199 Hg, 200 values than loess layers, meaning enhanced during...
Abstract Earth's climate system has experienced substantial millennial‐scale oscillations characterized by abrupt changes superimposed on orbital‐scale changes. However, the dynamic connection between millennial and orbital timescales remains elusive. Here, we provide a summer monsoon precipitation δ 18 O record spanning from ∼8 to ∼60.5 ka based oxygen isotopic composition of microcodium loess deposits Chinese Loess Plateau. This shows distinct precessional variations (23 ka) punctuated...
Abstract The 4.2 ka event is widely presumed to be a globally widespread aridity and has been linked several episodes of societal changes across the globe. Whether this climate impacted cultural development in south-central China remains uncertain due lack regional paleorainfall records. We present here stalagmite stable carbon isotope trace element–based reconstruction hydroclimatic conditions from China. Our data reveal sub–millennial scale (~5.6 4.3 ka) drying trend region followed by...
Abstract Trace elements in a speleothem have been considered to be effective proxies characterize hydroclimatic changes. In this study, we present trace element records of the penultimate glacial‐interglacial transition from 138 125.8 ka BP Shangxiaofeng cave northeastern China. We used two analytical methods, namely, inductively coupled plasma optical emission spectrometry (ICP‐OES) and Avaatech high‐resolution X‐ray fluorescence (XRF) core scanner. Both methods showed good consistency for...
The reconstruction of Asian summer monsoon (ASM) changes during the last glacial period is great significance for better understanding dynamics. phase relationship between Indian (ISM) and East (EASM) subsystems on different timescales still unclear. comparative analysis speleothem records in ISM region, EASM central China helps to clarify EASM. Based well-dated isotope stalagmite DDH-B15 from Didonghe (DDH) Cave Hanzhong, Shaanxi, we reconstructed ASM past 34–13 thousand years before...
Abstract The complexity of processes affecting soil organic carbon (SOC) turnover on spatio‐temporal scales often hinders the extrapolation results from specific sites to larger scales. This study presents Holocene speleothem U‐Th ages paired with 14 C carbonate and dissolved (DOC) through three caves located a north‐south transect China. deviations DOC show clearly spatial variability, they are positively correlated mean modern SOC time, suggesting that can be used infer turnover. We...
Speleothem δ13C in monsoonal China differs from speleothem δ18O, which is widely used as a climatic proxy for several complex control reasons. Nevertheless, records have the potential to reveal implications of hydroclimatic changes. This study reports record Didonghe (DDH) Cave central spanning 34 13 kyr BP. After we investigated factors that influence δ13C, found showed DDH can prompt directional shifts via local changes, such vegetation types, biomass, and rock–water interaction processes,...
Abstract. Paleoclimate proxies reveal a significant precessional impact on the low-latitude hydrological cycle. Classical theory suggests that precession modulates inter-hemisphere summer insolation difference, and hence controls meridional displacement of Inter-Tropical Convergence Zone. Accordingly, precipitation variations are expected to be in-phase (for Northern Hemisphere) or anti-phase Southern with Hemisphere insolation. However, increasing number proxies, particularly those...
