This study presents the first application of phytolith analysis in a multiproxy paleoenvironmental reconstruction in a coastal marine area in Brazil. It investigates the natural and anthropogenic influences on the evolution of Guanabara Bay (GB), one of the most urbanized regions in Southeastern Brazil. To achieve this, grain size, geochemical, mineralogical, and phytolith data were analyzed on a short piston core. The analysis revealed changes in the continental input of lithogenic materials and variations in the quantity and type of organic matter, linked to alterations in vegetation and sediment supply from the rivers over the last ∼2500 years. The general marine regression may have favored the sediment transfer from the rivers to GB, while the low hydrodynamic regime contributed to the accumulation and preservation of the sedimentary record. Sedimentological changes related to shifts in rainfall patterns and the degree of mineral weathering were observed. Three main phases of dryness have been identified. The earliest was recorded between ∼415 and 50 BC, during the Late Holocene Dry Period (or the Late Holocene Neoglacial Anomaly); the second one was registered between ∼800 and 1300 AD, during the Medieval Climate Anomaly; and the third one happened ∼ between 1550 and 1900 yrs AD, during the Little Ice Age (LIA). These three dryness events have been caused by shifts in the oceanic Intertropical Convergence Zone (ITCZ) and the South Atlantic Convergence Zone (SACZ). Although phytolith analysis has been conducted in a few marine environments, no previous studies have been conducted in Guanabara Bay or Brazilian marine systems. The multiproxy analysis, including phytoliths, enabled the identification of changes in primary vegetation types, changes in rainfall and sediment supply and anthropogenic impacts in Guanabara Bay.</div></div>","PeriodicalId":34142,"journal":{"name":"Quaternary Science Advances","volume":"19 ","pages":"Article 100285"},"PeriodicalIF":2.9,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Post-infrared infrared-stimulated luminescence dating shows that the entire sequence reaches back beyond 300 ka, and that the glaciofluvial-aeolian transition occurred during the penultimate glaciation at ∼160 ka.

The Cauvery Delta, the largest sediment deposit on Tamil Nadu's eastern coast, is chosen for the study. The study's methodology is structured into: (1) reconstructing a catalogue of significant flood events using documentary records; (2) mapping fluvial geomorphic landforms using satellite images; (3) spatially correlating the records obtained from documentary sources with landforms, and (4) identifying flood geomorphic landforms (FGL) and demarcating promising prospective locales for future chronological studies. It has been observed that the Cauvery River has experienced recurrent instances of flooding throughout the past 8000 years. The FGL mapped using digitally processed satellite images displayed 17 types of landforms. Subsequently, the FGL are precisely identified by spatially integrating documentary data with landforms. Braided bar, channel bar, lateral bar, channel islands, natural levees, paleochannels, older flood plains, point bars, oxbow lakes, and water bodies are the most promising FGL for paleoflood research.</div></div>","PeriodicalId":34142,"journal":{"name":"Quaternary Science Advances","volume":"18 ","pages":"Article 100281"},"PeriodicalIF":2.9,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143825530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The direct effects of the great shock and the following famine, exposure to coldness, and disease together killed more than 830,000 people, making the Huaxian earthquake the deadliest in history. Estimates of its magnitude vary widely, with intensity data leading to estimates of 8¼ to 8½, whereas geological estimates of slip and fault length suggest a range of 7.5–8.0, but with remaining uncertainty due to the lack of detailed measurements along the entire rupture zone. In this study, we use high-resolution digital elevation models (DEMs) derived from Pléiades stereo satellite imagery to map the surface ruptures and measure the fault scarps associated with the 1556 earthquake. We use the vertical offset measurements and the cumulative offset probability density (COPD) method to constrain the surface slip distribution of the 1556 event and to examine evidence for prior rupture. We find an average vertical displacement of 6.3 ± 0.7 m, consistent with a moment-magnitude (<em>M</em>_<em>w</em><em>)</em> of 7.3–7.9 that, although large, is much smaller than earlier estimates derived from seismic intensity data. Although the Huaxian earthquake is likely the largest known well-defined normal-faulting event in history, it aligns with the global pattern that normal-faulting earthquakes in continental interiors rarely exceed <em>M</em>_<em>w</em> 8.

Our findings highlight the central role of eccentricity in modulating the influence of high-latitude glacial climate variability on the northern Andes. During periods of high eccentricity (∼70–260 ka), we conclude that the region was shielded from northern high-latitude glacial ice-sheet dynamics by an intensified Walker circulation. After ∼70 ka, a weakening of this zonal circulation allowed high-latitude, millennial-scale glacial climate variability to penetrate deeper into the tropics, influencing the position of the ITCZ and the rainbelt. This shift in climate dynamics led to increased regional millennial-scale climate variability. A detrended correspondence analysis (DCA) on fossil pollen data highlights a contemporaneous compositional shift previously masked by glacial-interglacial vegetation changes. The observed ecological shift coincides temporally with predictions of elevated speciation rates in mechanistic simulations. Combined, these results suggest a long-lasting environmental impact from glacial millennial-scale climate dynamics, supporting the hypothesis that increased environmental dynamism during glacial periods may trigger the speciation pump in the Northern Andes more than glacial inceptions or terminations. These findings underscore the evolving nature of regional climate drivers and their complex interplay with ecology, offering new insights into the role of climate variability in shaping biodiversity in this hotspot.</div></div>","PeriodicalId":34142,"journal":{"name":"Quaternary Science Advances","volume":"18 ","pages":"Article 100278"},"PeriodicalIF":2.9,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
