It consisted of a pair of mainshocks occurring within minutes of each other, affecting a vast region between the northern Vallo di Diano and the northern Agri Valley, two Quaternary intramontane basins separated by the Maddalena Range. The earthquakes were likely triggered by the cascading rupture of two adjacent, aligned normal faults, whose exact length and location are uncertain and debated, especially concerning the southern one. This study focuses on the northern normal fault, here named Caggiano fault system, which extends NW-SE for approximately 32 km across the Meso-Cenozoic carbonate of the Maddalena Range. After mapping the fault scarp using 1950s aerial photos and LiDAR-derived DTM, we conducted geological field survey of the entire fault traces, performing electrical resistivity tomography preparatory to paleoseismic trenching. Subsequently, we excavated trenches and pits, collecting numerous samples for radiocarbon dating. Results provide conclusive evidence of surface faulting to the post-Last Glacial Maximum-Holocene, indicating the Caggiano fault system as a reliable candidate for the 1857 earthquake, as well as earlier events, such as the one in 1561 and previously undocumented earthquakes in the Middle Age and Roman times. These findings represent a robust contribution to future seismic hazard assessments, which require reliable identification and seismogenic characterization of active fault systems.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"365 ","pages":"Article 109508"},"PeriodicalIF":3.2,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144535760","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}

Modern ecological studies of the past several decades inform the interpretation of stratigraphic records, and increasingly both modern surface-sample datasets and stratigraphic records are being added to publicly available databases like the Neotoma Paleoecology Database. In this paper, we broadly synthesize results of calibration studies during the past ∼35 years, and then use data from the Neotoma Paleoecology Database to examine morphospecies-environment relationships in calibration datasets from the northern hemisphere and directly compare subfossil and modern testate amoeba communities to assess the strength of modern analogues for subfossil samples in North American stratigraphic records. Results confirm the consistent and central importance of surface-moisture in controlling testate amoeba communities in peatlands, with similar community-moisture relationships across the Northern Hemisphere. However, many subfossil communities have few good modern analogues, likely due to a combination of factors including differential decomposition of taxa extending beyond the well-documented poor preservation of weakly idiosomic tests. Many subfossil samples contain high abundances and unusual combinations of taxa that are not well represented in modern datasets, and the causes and implications of subfossil communities with poor modern analogues deserve greater attention by the research community. The Neotoma Paleoecology Database is a valuable shared resource, and its continued development will enable the examination of research questions focused on understanding the variability and structure of modern and subfossil testate amoeba communities, as well as moisture reconstructions in both time and space.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"366 ","pages":"Article 109491"},"PeriodicalIF":3.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144517239","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}

As result, the relation between climate cooling and these sedimentary systems is still poorly understood. Severe climate cooling occurred during the Late Pleistocene MIS 5-MIS 4 transition, as captured within the shallow marine deposits of the Brown Bank Formation (Fm), which occurs between 0.1 m and 40 m below the present southern North Sea floor. To improve our understanding of the character and complexity of the depositional system, as well as the environmental response during the rapid climate cooling it portrays, we map the hitherto poorly constrained extent and architecture of the Brown Bank Fm within part of the Dutch sector of the North Sea. We document and map four seismic facies units (BB1-BB4) that are attributed to variations in tidal energy and pro-deltaic sediment supply. Pollen, diatom and mollusc assemblages reveal that the palaeoenvironment remained shallow marine throughout deposition and provide evidence for two cooling phases. The pollen assemblage also indicates that during this period forests changed to open woodlands in this period. Linking the palaeoenvironmental data and new luminescence ages of the four units with the Greenland NGRIP δ¹⁸O_ice chronology, suggests that deposition of the units occurred during a relatively short time. The new analyses from the Brown Bank Fm suggest that the North Sea became disconnected from the Atlantic Ocean at its southern outlet (the Dover Strait) around the start of MIS 5a (ca. 88 ka) and that the floor of the southern North Sea became completely exposed around 72 ka.</div></div>","PeriodicalId":20926,"journal":{"name":"Quaternary Science Reviews","volume":"365 ","pages":"Article 109442"},"PeriodicalIF":3.2,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144490334","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 new data constrain deglaciation by 10.0–9.5 ka. Combining our new data with previously unused sea-level indicators from penguin remains redefines understanding of RSL changes after deglaciation.

A reinterpretation of an existing marine core provides circumstantial evidence that RSL fell below 5 m ASL at c. 3.6–2.8 ka which would be coincident with a previously inferred retreat-readvance of the ice margin at this time. Overall, the timing of the Holocene sea-level high stand in the Windmill Islands is similar to other sites around East Antarctica.

While significant progress has been made in studying sediment provenance from rivers, oceans, and Loess deposits, lake sediment provenance studies remain relatively scarce particularly in eastern China, which constrains our ability to accurately interpret climate signals through sediment source analysis and basin evolution. This study systematically analyzed rare earth elements (REEs) in the long drill core LZK1502 from Chaohu Lake, eastern China. The objective was to identify the characteristics and influencing factors of REE variations since 35.7 ka BP (before present, where present = 1950 CE) and explore the relationship between sediment sources and environmental changes. The results show that REEs are enriched in light REEs and depleted in heavy REEs, with moderate to slight negative Ce and Eu anomalies. REE compositions are closely linked to grain size, chemical weathering, and environmental changes. Climatic conditions and geological factors indicate that environmental changes significantly influenced the sediment provenance of Chaohu Lake. During the last glacial period, when the climate was predominantly cold and dry, sediments were primarily derived from terrigenous clastic materials weathered from surrounding sedimentary rocks. In the Holocene, the dominant sediment source shifted to weathered clastic material from granite and volcanic rocks as the lake area expanded. During the significant expansion periods of Chaohu Lake, weathered volcanic material from the Lujiang-Zongyang volcanic basin became the primary source of sediments by long-distance transport. In contrast, during periods of moderate expansions, when the lake area contracted, medium-distance weathering products from granite in the Northern Huaiyang volcanic belt became the dominant source.
