However, eolian deposition is influenced not only by climatic changes in source regions, but also by the topography evolution along dust transportation pathways, a factor often overlooked. The Chinese Loess Plateau (CLP) is the largest dust accumulation region in East Asia, which is bounded by boomerang-shaped mountains. Here, we used apatite (U<img>Th)/He thermochronology and thermal modeling to reconstruct the uplift history of the West Qinling, an orogenic belt adjacent to the earliest (25–22 Ma) eolian red clays in the CLP. Our findings indicate that the West Qinling experienced tectonic uplift during the late Oligocene-early Miocene, coeval with the formation of the earliest eolian red clays in the CLP. Considering the tectonic activities surrounding the CLP and updated climatic records in Central Asia and Pacific Ocean, we propose that the appearance of the late Oligocene-early Miocene eolian red clays in the CLP likely reflects the formation of geomorphologic conditions conductive to dust accumulation and preservation. This phenomenon is not limited to East Asia, but is also commonly observed in other active orogenic belts. Thus, it ought to be cautious to assess the geological significance of the initial eolian deposition, particularly in active orogenic belts.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"253 ","pages":"Article 104956"},"PeriodicalIF":4.0,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510704","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}

Our data reveal non-conservative mixing dynamics in surface bay water, showing measurable Sr removal (7.7–69.8 %) and ⁸⁷Sr/⁸⁶Sr enrichment (+0.000001–0.000334) relative to theoretical mixing models.

Carbonate weathering dominates this flux, accounting for &gt;99.9 % of the total Sr input. FSGD delivers 2.0–2.1 times more Sr to the bay than riverine inputs, thereby establishing its role as the dominant terrestrial source of Sr. This predominance is likely driven by tropical climate-enhanced weathering and the region's carbonate-dominated sedimentary environment. Building upon this study, we upscale our findings to a global dimension, estimating that tropical continental islands supply 26–47 % of global FSGD-derived Sr fluxes to the ocean—a previously underquantified yet geochemically critical source that reshapes contemporary understanding of marine Sr mass balance.</div></div>","PeriodicalId":55089,"journal":{"name":"Global and Planetary Change","volume":"253 ","pages":"Article 104955"},"PeriodicalIF":4.0,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510705","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}

We address this debate through integrated geochronological and geochemical investigations of Middle-Late Permian granitoids (252–260 Ma) from the Bainaimiao Arc Belt, a critical component of the North China Collage System. Zircon U<img>Pb data resolve two distinct magmatic phases: (1) 258–260 Ma calc-alkaline granites exhibiting arc-like signatures (enriched LILEs, depleted HFSEs), and (2) 252–254 Ma highly fractionated alkaline granites with elevated SiO₂ (∼66.49–77.71 wt%), total alkalis (Na₂O + K₂O = ∼6.88–9.55), and diagnostic trace element ratios (Nb/Ta = ∼4.4–16.8; Zr/Hf = ∼13.5–39.2).

This study explores its effects on terrestrial ecosystems at high latitudes for the first time, specifically focusing on the Junggar Basin in northwest China, located at approximately 60°N. By utilizing organic geochemical analyses of fine-grained sedimentary rocks from the Lower Jurassic Sangonghe Formation, we mapped the presence of higher-plant-derived hydrocarbons to reconstruct vegetation shifts before, during, and after the N-CIE interval. Our findings reveal an initial dominance of ferns, with a shift toward gymnosperms such as conifers and cycads during the event, and a subsequent return to fern dominance, as recorded by anomalies in di- and tri-cyclic aromatic hydrocarbon fractions. This suggests significant ecological adaptations and potential recovery or further adaptation following the N-CIE. Our findings underscore the sensitivity of high-latitude terrestrial ecosystems to dramatic climatic events like the T-OAE, emphasizing their importance in understanding past environmental changes and improving predictions of future ecological responses.

Meanwhile, SSTs in the KCE and northern CC regions decreased considerably, implying southward displacement of the northern boundary of the NPSG. The post-iNHG enhancement and southward shift of the NPSG may have resulted from a more La Niña-like state in the equatorial Pacific and atmospheric circulation reorganization associated with high-latitude cooling in the Northern Hemisphere, as suggested by the North Pacific zonal and meridional SST gradients.

Here, we present a comprehensive analysis of proxy archives for island erosion and weathering, terrestrial matter supply, surface ocean productivity, downward export of biogenic material, and bottom-water redox, all closely linked to orbital variations of iron fertilization, along the continental slope offshore of northern Papua New Guinea since 275 kyr. Our findings reveal a prominent precession cycle across these integrated records, aligning with changes in January–March insolation at 5°S. The observed temporal coupling indicates that heightened precipitation and erosion in northern Papua New Guinea stimulated nutrient input, thereby enhancing surface ocean fertilization, biologic production, and particulate carbon burial in the western equatorial Pacific during periods of high January–March insolation at 5°S. This caused the area to be a significant atmospheric CO₂ sink during La Niña-like conditions.
