However, land use change also occurred throughout this period, and the relative importance of human activities is poorly constrained. Here we challenge a purely climatic explanation by showing that anthropogenic activities could have led to increasing dust emissions in late-Holocene West Africa. To characterize land use effects on dust, we developed a dust mobilization potential index that represents the intensity of land use and landscape modification based on archaeological evidence and contemporary observations of land use effects on dust mobilization. Our analysis reveals that the locus of human-induced dust emissions shifted over time, with initial increases in the southern Sahara and Sahel coinciding with early agricultural and pastoral intensification, followed by gradual southward expansion into more humid regions alongside the spread and diversification of farming and herding practices. Notably, human-induced dust emissions continued to increase even during periods of relative climate humidity, including 3500–2500 BP and the Medieval Climate Anomaly (1150–650 BP), a trend inconsistent with purely climatic forcing but consistent with a concurrent rise in in the intensity of human activities. Our results suggest that while large-scale climate change established the overarching aridification trend in Holocene West Africa, progressive land use amplified the landscape's sensitivity to erosion, leading to a dust response disproportionate to climatic forcing alone.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"257 ","pages":"Article 105175"},"PeriodicalIF":4.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145491997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we integrate geological records with climate simulations to establish quantitative relationships between bauxite and kaolinite occurrences and temperature-precipitation patterns over the Phanerozoic. Bauxites and kaolinites were mainly located in the tropics in the Paleozoic. They shifted to the subtropics for much of the Mesozoic and Cenozoic.

Compared with research on marine environment, studies on the terrestrial sulphur cycle and its relationship with key geological events, such as volcanic activity or hydrothermal fluids, are more limited. The Fengcheng Formation in the Mahu Sag of the Junggar Basin in northwestern China, which was deposited during the Carboniferous to early Permian in an alkaline lake, is an ideal research object for studying the relationship between the terrestrial sulphur cycle and geological events. Therefore, in this work, we established a link between volcanic activity and the alkaline lacustrine carbon–sulphur cycle during the Carboniferous–Permian Fengcheng Formation through petrologic, geochemical, and geophysical data from the MY1 Well in the Mahu Sag. The results revealed that (1) multiple volcanic episodes occurred during the deposition of the Fengcheng Formation, as evidenced by high mercury (Hg) concentrations, high Hg/S ratios, increased sulphate concentrations and large negative pyrite sulphur isotope (δ³⁴S_py) values (to −20.52 ‰); (2) long-term ferruginous bottom water conditions may have been conducive to the preservation of organic matter; however, sulphate from volcanic activity promoted bacterial sulphate reduction, resulting in intermittent alternating euxinic conditions, as evidenced by iron speciation, molybdenum concentrations, and framboid and euhedral pyrite morphologies, which may have resulted in some consumption of organic matter; and (3) after volcanic activity, most of the sulphate in the lake water was depleted, and the bottom water gradually closed and was continuously enriched with positive δ³⁴S_py. Therefore, volcanic activity appears to have been the key factor controlling the sulphur cycle and organic matter enrichment through increased sulphate fluctuations in the oldest alkaline lake during the deposition of the Fengcheng Formation. This study sheds new light on the sulphur cycle of ancient alkaline lakes and can serve as a reference for organic matter enrichment under different mechanisms in shale.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"257 ","pages":"Article 105254"},"PeriodicalIF":4.0,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145785311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantitative analysis of <em>n</em>-alkane carbon isotope values suggests an estimated average mean annual precipitation of ∼1200 mm/yr across these stages, with the minimum values recorded between late JBS II and early JBS III.
