Although previous studies have shown that the paleoenvironment and geological processes contributed to the organic matter accumulation (OMA) and carbon isotope excursions (CIEs) during the late Ordovician–early Silurian, the dominated controlling factor for the OMA and the origins of CIEs still remains unclear due to complex interaction between var...

Studying the evolution history of the southwest summer monsoon (SSM) throughout geological time, particularly during its strongest period in the Holocene, can improve our understanding of its variation and driving mechanisms, and even help predict future climate changes, due to its significant social and economic implications. Here, we reconstructe...

The links between chemical weathering on a continental scale and climate have long been a central issue in Earth science. However, the limited knowledge of the interconnections between weathering and climate impedes our understanding of its role in the evolution of the Earth's climate. The Tibetan Plateau is the world's highest and largest plateau...

The climate reconstruction of the Tibetan Plateau, which was called the Third Pole Environment, has been a research hotspot in recent years. However, there are few studies on C3 and C4 plants evolution and it is area of active debate on whether there are C4 plants exist on the Tibetan Plateau. In this study, the paleoclimate of the Hurleg Lake on t...

利用气相色谱－质谱（ ＧＣＭＳ） 联用技术对我国大兴安岭北部霍拉盆地湖泊沉积物进行了有机分子地球化学分析， 检测出了丰富的正构烷烃。 本研究主要讨论了正构烷烃的分布特征及其长链正构烷烃的单体碳同位素组 成， 结合ＡＭＳ１４Ｃ 年代数据， 重建中国东北大兴安岭地区末次冰盛期以来的古植被及古气候变化。 正构烷烃分布 特 征 表 明 ， 末 次 冰 盛 期 以 来 ， 霍 拉 盆 地 湖 沼 沉 积 物 长 链 正 构 烷 烃 呈 现 明 显 的 奇 碳 优 势 ， 主 峰 碳 主 要 为 ｎＣ３１ ， 指 示 有机质主要来源于陆生高等植物， 且草本植物输入占优势， 木本植物输入丰富。 陆生高等植物来源的长链正构烷 烃 单 体 稳 定 碳 同 位 素 的 记 录 显 示 ， 末 次 冰 盛 期...

The Ediacaran–Cambrian period witnessed episodic extinctions, oxygenation of seawaters, Cambrian explosions, and tectonic events. However, compared with the various high-resolution geochemical records of the early–middle Ediacaran and Cambrian, the available geochemical record of the latest Ediacaran (551–542 Ma) is scarce (especially the strontium...

Since the Cenozoic, the earth entered a period of relatively active tectonic movement, which led to significant environmental and climatic shifts, including inland drought in Asia, global cooling, and the formation of the Asian monsoon. The Asian aridification has a far-reaching impact on the human living environment, and so do the climate changes...

To reveal the heat source and its formation mechanism of the northern Yadong-Gulu rift (YGR), we analyzed the helium isotope, carbon isotope (δ¹³CCO2), and CO2/³He and CH4/³He ratios of hot spring gases for tracing the source of volatiles and discussing their geological significance. The results show the following: helium is mainly derived from the...

The Eocene is the initial stage of the Cenozoic global cooling. Compared with the abundant marine records, the continental records of Eocene are scarce. Throughout the Eocene, a series of continuous deposition of gypsum and volcanic tuff-bearing red clastic sediments have developed in the Nangqian Basin (NB). In this work, representative sediments...

Thick and continuous deposits in the Linxia Basin, located in the landing area of westerlies and monsoons, offer a good opportunity for understanding the climatic evolution and tectonic activities. However, detailed paleoclimate reconstruction based on lipid biomarkers was rare, which limited our further knowledge, even though there were some relev...

The biosphere experienced episodic perturbations during the Neoproterozoic–early Cambrian, accompanied by major fluctuations of the carbon cycle. However, compared to the Ediacaran–early Cambrian, geochemical records of the Cambrian Toyonian Stage (Longwangmiao), which contains the significant Redlichiid–Olenellid Extinction Carbon Isotope Excursio...

Hydroclimate evolution history and changes in the Tibetan Plateau play significant roles in depicting paleoclimate and evaluating climatic conditions in the coming future. However, the interaction of the westerlies and the Asian monsoon complicates our understanding of the mechanism of climate variation over the Tibetan Plateau. In this study, we a...

An accurate chronological framework is vital if we are to use lacustrine sediments on the Tibetan Plateau (TP) for paleoclimate reconstruction. Radiocarbon (¹⁴C) dating is the most frequently used method for dating late Quaternary lacustrine sediments. However, it is often affected by potential reservoir effects. Owing to the complex hydrogeology a...

Alternating conditions from cold to warm periods since the Late Glacial provided a significant contrast for future hydroclimatic variation, as did the corresponding variation in vegetation. To predict the potential variability in C3/C4 biomass under future warmer climatic conditions, we determined the current spatiotemporal distribution of C3 and C...

Studies on long‐chain n‐alkan‐2‐ones from lake sediments remain sparse. In this study, we present an n‐alkan‐2‐one record from Qionghai Lake, southwest China, to assess the paleoclimate significance of variations in their compositions. A homologous series of n‐alkan‐2‐ones ranging from C21 to C35 were identified, with maximum concentrations of the...

The organic-rich shale of the Upper Carboniferous-Lower Permian transition period in the eastern margin of the Ordos Basin, China, was formed in a marine-continental facies sedimentary environment. With a high content of total organic carbon (TOC) and a large cumulative thickness, it is considered a good source rock for shale gas development. The s...

Black shale deposited in the transitional period from the Late Ordovician to Early Silurian is the most important source rock and shale gas reservoir in the Yangtze region of South China. However, the source of these sediments is still controversial. In this paper, the changes in total organic carbon (TOC), total sulfur (TS), organic carbon isotope...

The Indian summer monsoon (ISM) significantly influences the climate of southwestern China; however, continuous quantitative temperature reconstructions since the Last Glacial Maximum are rare, which limits our understanding of ISM evolution. In this study, we analyzed the branched glycerol dialkyl glycerol tetraethers (brGDGTs) from a lacustrine s...
