Over the past three decades, these deposits have attracted considerable attention in Quaternary paleoclimate research. Nevertheless, our understanding of these high-altitude aeolian deposits is significantly less than that for similar deposits in the low-altitude regions of the Eurasian continent. To better comprehend this important archive, it is essential to integrate knowledge from various perspectives. However, there is a lack of consensus regarding their formation, distribution, chronology, provenance, and paleoclimatic history across different timescales. Here, based on our recent field investigations and new data, along with previously published data, we present the results of a systematic analysis of aeolian deposits on the southern TP. Our principal results and findings are: (1) We present up-to-date maps of the aeolian deposits, consisting of an overview map of the overall spatial distribution, and six high-resolution regional maps highlighting details of the depositional areas. Loess and sand dunes have accumulated within the six subdomains, following the global pattern of dust accumulation along rivers in arid and semi-arid regions. (2) Based on paleomagnetic and ESR dating, the oldest aeolian sediments were formed during the middle Pleistocene. The probability density of 220 OSL and AMS <sup>14</sup>C ages reveals that 98.7 % of the young sediments accumulated since the last interglacial, with the majority (66.4 %) forming during the Holocene. A comparison of age clusters with records of ice volume, temperature, precipitation, vegetation, and paleolakes revises previous hypotheses regarding the factors influencing dust deposition, emphasizing the dominant control of climate change. (3) The aeolian sediments are of local origin and their sources remained relatively stable over time. Quantitative analysis of 48 samples using geochemical fingerprinting showed that the aeolian sediments are a mixture of various clastic materials derived from upstream areas, with the predominant contribution from sand dunes (58.7 %). (4) We examined the climatic evolution of this region and its driving mechanisms during the middle to late Pleistocene and the Holocene. This analysis suggests that changes in cold and warm season insolation were the primary external drivers of moisture and dust activity on both orbital and sub-orbital scales. The winter mid-latitude Westerlies and the Indian summer monsoon, which are influenced by these seasonal insolation variations, regulated the moisture evolution, while the near-surface winds, primarily driven by cold season insolation and influenced by ice volume and oscillations in North Atlantic climate, played a significant role in modulat","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"261 ","pages":"Article 105035"},"PeriodicalIF":10.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143136871","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}

The Siberian Platform around the Precambrian–Cambrian transition shows a wide distribution of the marine carbonate facies and hence has high potential for studying the associated endobenthic ecosystem transformations. This study summarizes the results of paleoichnological studies in the terminal Ediacaran and Terreneuvian strata (∼550–521 Ma) in nine regions of the Siberian Platform periphery. The ichnoassemblages are grouped in three stratigraphic intervals (terminal Ediacaran, Fortunian Stage, Cambrian Stage 2) and attributed to sedimentary environments within the models of siliciclastic shelf and/or carbonate ramp. The evolution of the ichnoassemblage structure is evaluated applying the ecosystem engineering and ecospace occupation analyses. The study reveals that the terminal Ediacaran fossil record of the Siberian Platform lacks undisputed trace fossils. In the Terreneuvian, the general patterns of spatiotemporal development of endobenthic communities in the carbonate-associated marine environments generally coincided with those in the siliciclastic basins.

In China, however, most of the pre-Devonian shales are postmature, resulting in a gradual convergence in the chemical composition and structure of organic matter (OM). This convergence complicates OM identification under optical microscope, making it challenging to trace its genesis and evolution due to similar optical characteristics. Additionally, the absence of true vitrinite particles poses an additional challenge in the evaluation of thermal maturity of these shales, a challenge that has persisted for decades. This study compares detailed optical characteristics and genesis of selected OM types, namely, graptolite, vitrinite-like maceral (VLM), solid bitumen (SB) in the pre-Devonian shales to improve identification and differentiation between these macerals. The physicochemical evolution of OM is reviewed based on the naturally and artificially matured samples, with emphasis on the organic petrology and petroleum production in some of the most extensively studied pre-Devonian shales globally. VLM and graptolites exhibit higher reflectance and stronger anisotropy than co-occurring in-source SB, with their reflectance as indicators to evaluate OM maturity in these marine shales. VLM can be distinguished from SB by its elongate and syndepositional occurrence, and from graptolites by the characteristic biological structures of graptolite. The origin of VLM is hypothesized to be a product of early diagenetic anaerobic biodegradation of lamalginite and/or bituminite in the Precambrian shales, although its origin in the Cambrian shales remains unclear. On the other hand, in-source SB is derived from the transformation of liptinites or from the cracking of the residual petroleum, or a combination thereof. Graptolites are associated with high total organic carbon (TOC), S₁, S₂, and hydrogen index (HI) contents, with kerogen predominantly classified as Type II-III, indicating significant hydrocarbon generation potential. Notably, in-source SB plays a significant role in gas generation. In the early mature pre-Devonian shales, OM mainly consists of lamalginite and bituminite; whereas in-source SB becomes the dominant OM in the postmature pre-Devonian shales. Non-granular graptolites are commonly observed in the Ordovician-Silurian Wufeng–Longmaxi shales, contributing significantly to OM. A comparison of naturally and artificially matured samples suggests that low-maturity liptinites transform into SB as thermal maturity increases. This finding is essential for reconstructing the original composition and hydrocarbon potential of these economically significant marine shales.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"261 ","pages":"Article 105027"},"PeriodicalIF":10.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143136866","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}

This review synthesizes data from fifty-two global cases of CRR where surface deformation affected rivers and identifies the key physical and environmental parameters that control riverine flood hazard in earthquakes. We identify four primary CRR classes, ranging from channel-confined ponding to overbank flooding and avulsion, wherein a river shifts into an enduring new course within the floodplain. CRR susceptibility governs the likelihood, spatial extent, and longevity of CRR, and links back to the characteristics of the surface deformation, river planform, and host environmental setting. Dip-slip fault ruptures, with a large vertical separation at the surface capable of damming river channels, are the primary driver of CRR. Multi-meter dip-slip offsets are also linked to fault-block tilting, which reduce or reverse the gradients of overlying channels. These tilted fault blocks can induce coseismic flooding or avulsion away from the principal fault, with cases documented up c. 10 km upstream from the fault-river intersection. Lateral offsets can amplify or modulate CRR but are generally less effective than vertical offsets at causing them. Two-thirds of CRR cases occurred in single-thread rivers, the majority of which are meandering systems occupying intermontane or lowland basins. Liquefaction-prone substrates in these floodplains exacerbate CRR impacts through ground deformation that disrupts river channel profiles and the local water table. Overbank flooding, lake formation, and prolonged surface flooding are common outcomes near meandering channels and may occur away from the principal fault. Confined braided rivers with high width-to-depth ratios are more resistant to overbank flow and avulsion. In unconfined settings, erodible substrates, and low lateral bank stability amplify the potential for channel scour and rapid avulsion. Braided floodplains often host dense networks of paleochannels within their floodplain, and in any environment, paleochannels enhance the potential for, and geographic extent of flooding and avulsion. High discharge conditions elevate the potential for overbank flow and avulsion, and the hazard posed by CRR may be higher in regions where the climate is perennially or seasonally wet. The risk posed by CRR during earthquakes is heightened in areas where population expansion and land reclamation in flood and liquefaction-prone zones is commonplace. A method to assess CRR risk in advance is required, and a probabilistic framework incorporating uncertainties in fault behaviour, recurrence intervals, and flood-rating curves may offer a way to evaluate absolute hazard in areas where faults and rivers intersect.

These nodules are primarily formed through the biomineralization process driven by favorable redox reactions and microbial activity. The formation of FMNs in the soil is governed by complex geochemical interactions and influenced by both biotic and abiotic factors, such as temperature, pH, organic matter, redox potential (Eh), wet/dry cycles, and nucleation sites. FMNs typically vary in size, ranging from a few microns to several centimeters, and exhibit diverse shapes, from spherical to irregular. These nodules play a crucial role in nutrient cycling and the adsorption of heavy metals, including phosphorus, lead, copper, zinc, cobalt, and nickel, thereby improving soil quality and preventing metal leaching into aquatic environments. The ion exchange during redox reactions, complexation, occlusion, and adsorption are the key mechanisms through which heavy metals can become immobilized in soil FMNs. The formation of FMNs involves Mn-oxidizing bacteria, such as <em>Bacillus, Pedomicrobium, Erythrobacter, Pseudomonas putida, Geobacter,</em> and <em>Leptothrix discophora,</em> which use specific functional genes such as <em>mnxG, moxA, mopA, CumA, ombB, omaB, OmcB,</em> and <em>mofA</em> to facilitate manganese oxidation. This process reacts with geological material, resulting in the precipitation of metal leachates and the development of metal oxide coatings that serve as nucleation sites for FMNs. Such microbial activities are not only essential for FMNs formation but also for trapping heavy metals in soil, highlighting their importance in soil biogeochemical cycling and ecological functions. However, further research is needed to unravel the complex biogeochemical interactions that influence FMNs growth and composition, as well as to understand the stabilization and release dynamics of nutrients and heavy metals, and the roles of microbial communities and functional genes involved in these processes, particularly in relation to soil fertility and plant nutrition.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"261 ","pages":"Article 105029"},"PeriodicalIF":10.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874281","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}
