To evaluate the viability of the shallowing-upward assumption, a review of mid- to late-Holocene coastal carbonate successions from many “classic” peritidal settings was undertaken. This assessment shows that the simple shallowing-upward assumption is largely unsupported by the aggregate of modern-systems observations. Tidal flats generally do not prograde directly into lagoons to create muddy shallowing-upward cycles, and lagoons are not observed to prograde over their own protective shoal barriers to create grainy shallowing-upward cycles. Instead, transgressive deposits comprise an important component of carbonate depositional successions, forming deepening-upward motifs, where cycle-base tidal-flat and lagoonal remnants are overlain by a ravinement surface, signifying the passing of a transgressing carbonate barrier, and then are overlain by open-platform deposits. Overlying this, regressive deposits, where present, are represented by lagoonal abandonment and grainy shoreface progradation capped by strandplains, with overlying accommodation only for thin, discontinuous, intertidal mud flats and their subtidal drainage channels in inter-ridge swales. These observations indicate that the construct of the parasequence is less useful than that of a high-order sequence containing transgressive and regressive components. The implications of these observations and interpretations are wide-ranging and have generated the need for updated sequence-stratigraphic models for coastal carbonates based on modern coastal systems, and with which the rock record can be compared. These models are meaningfully different from models currently in use with respect to predictions of large-scale subsurface connectivity.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"269 ","pages":"Article 105201"},"PeriodicalIF":10.8,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503850","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 governing rheological constitutive law of the flowing mixture plays a crucial role in assessing their mobility and consequences. Developing a generic constitutive law, capable of capturing the evolving nature of mixture properties across different flow regimes in a landslide hazard chain, requires the incorporation of several physical concepts and is an active research question. This technical review presents a comprehensive review of existing rheological laws by classifying them into classic, modern, and physics-based mixture laws. Firstly, a preliminary classification of particle-fluid mixtures is proposed, encompassing dilute, moderate, and high ranges of solid concentrations. Next, following the continuum mechanics, the various types of particle-fluid mixture representations, from single-phase to multi-phase conceptualizations are presented. With a focus on flow index classification, the classic laws that assume a fixed relation over a single flow regime are explored. By switching to different flow regimes, rather than flow indexes, the modern laws that aim to capture the rheological behavior of flowing mixtures across different flow regimes are reviewed. Finally, the physics-based mixture rheological laws which combine the existing classic and modern rheological laws for fluid and solid phases, and further include additional novel rheological laws for interphase interaction forces, are reviewed. This review enlightens the existing research trends on classic and modern rheological laws, describes their capabilities, and highlights missed concepts that are required for the development of a generic rheological law for landslide hazard chains. Enhanced understanding of the evolution of rheological behavior of flowing mixtures over various flow regimes in a landslide hazard chain improves further studies on hazard simulation and prediction, risk mitigation, and land use planning.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"269 ","pages":"Article 105204"},"PeriodicalIF":10.8,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503851","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}

Although South China Block (SCB) is renowned for reef proliferation in the eastern Palaeotethys, reef growth and their global implications remain under-explored. Using data from 353 references and 6731 thin sections, this study provides a comprehensive summary regarding reef ecosystems of SCB, plus comparison and integration with global records. Two main findings are outlined: (1) <strong>Reef growth</strong>. Three well-differentiated ecological associations and six high-resolution developing stages are recognised, and the mid-Givetian marked the peak of reef-building. The transition from epicontinental seas to rifting platforms reflects reef expansion from extensive open marine biostromes to barrier reef–lagoon communities. Reef growth was driven primarily by climate, temperature, and sea-level changes/tectonic activities, facilitating carbonate precipitation and extensive shallow-water habitats. (2) <strong>Global implications</strong>. Compared with major reef regions, the significance of SCB is noted in three aspects, including abundant fossil materials, unusual palaeogeographic location (eastern Palaeotethys), and exceptional reef pattern (broad inland sea to platforms and intra-platform basins). Based on the newly refined reef database, the global spatial distribution of Givetian reefs indicates SCB as a reef-building hotspot in eastern Palaeotethys. Moreover, the new temporal trajectory implies the reef peak occurred earlier in the Middle Devonian, supporting Givetian as an acme of Phanerozoic reef-building. Overall, this study highlights the underestimated role of SCB in understanding global Givetian reef expansion, Phanerozoic reef evolution, and the intricate interplay of local/global factors controlling reef growth.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"269 ","pages":"Article 105202"},"PeriodicalIF":10.8,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144503856","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}

Recent discoveries of new marine-sedimentary Mn deposits and the application of advanced analytical methods have led to fresh insights into marine-sedimentary Mn metallogenesis. Mn is a redox-sensitive element. However, Mn cycling, which encompasses transport, deposition, and mineralization, is not a straightforward redox chemical process. Over the past two decades, studies on the biogeochemical behaviors of Mn and geological case studies of sedimentary Mn deposits have highlighted the crucial role of microorganisms in Mn cycling, which exceeds that of inorganic reactions alone. Nevertheless, the specific geoenvironmental conditions that facilitate microbially mediated Mn metallogenesis and the interrelationships among these events remain unclear. In this study, we review significant marine-sedimentary Mn deposits throughout geological history and their metallogenic geoenvironmental contexts. Our findings suggest that, despite the extensive temporal gaps between sedimentary Mn deposits, they likely share a similar metallogenesis mechanism. Pre-accumulated Mn(II) is converted to Mn oxides through the activation of multicopper oxidase enzymes under obligatory oxic conditions. In deposition sites with sufficient organic matter, heterotrophic microbes subsequently reduce Mn oxides to Mn carbonates by coupling with organic matter decomposition under suboxic or anoxic conditions. We propose four essential geoenvironmental prerequisites for large-scale Mn metallogenesis: the Mn source, high availability of molecular oxygen in water, a redox-stratified restricted setting, and the exchange of anoxic with oxic water columns. These conditions fundamentally arise from the breakup and assembly of supercontinents throughout Earth's history. Rifting has created a series of restricted basins, where hydrothermal activity has provided a substantial source of Mn(II). Continental inputs from weathering-derived Mn, including lateritic crusts, may also play a crucial role in the genesis of large sedimentary Mn accumulations and should not be overlooked. The sustained increase in atmospheric and hydrospheric oxygen levels has primarily been driven by photosynthesis, mantle overturning, and the expansion of continental regions. The anoxic depths of redox-stratified restricted rift basins have served as effective reservoirs for pre-accumulated Mn(II) and have provided refuge for calm biomat formation by limiting debris input. The exchange of oxygenated surface water with anoxic, metal-rich water in deep basins, facilitated by currents or fluctuations in sea level, creates the oxic conditions required for the enzymatic processes that promote microbial Mn(II) oxidation.

Due to its specific formation conditions and its high instability in acidic environments, laumontite provides a key geological indicator for analysing sedimentary-diagenetic system and identifying high-quality reservoirs in middle-deep strata. This study offers a comprehensive review of the distribution, occurrence, chemical composition, genesis, controlling factors, and the impacts on hydrocarbon reservoirs of laumontite in the sedimentary rocks of typical non-marine basins in China, such as the Junggar Basin, the Ordos Basin, and the Sichuan Basin. Previous research indicates that laumontite commonly develops as a continuous or patchy cement, fracture filling, and replacement product within vertically stacked deltaic subaqueous distributary channels. Sandstones enriched in plagioclase or volcanic material are considered ideal host rocks for laumontite formation. During eodiagenesis (&lt;85 °C), laumontite extensively fills intergranular pores, with individual crystals typically exhibiting a long prismatic habit, and commonly occurring in association with clay minerals, quartz, and heulandite. During mesodiagenesis (85–175 °C), laumontite occurs as patchy intergranular fillings, with individual crystals progressively developing a short prismatic morphology, and is mainly associated with calcite, illite, quartz, and albite. Laumontite in sedimentary rocks is typically characterised by a low Si/Al ratio (2.00–2.20), and its chemical composition shows no systematic variation with temperature or occurrence. Formation mechanisms of laumontite include the albitisation of plagioclase, transformation of volcanic material, and alteration of early-formed zeolites. Incomplete transformation of plagioclase may result in a higher Si/Al ratio in laumontite. Fluid inclusion homogenisation temperature data indicates laumontite in sedimentary rocks primarily forms within a temperature range of 60–140 °C. The transformation of plagioclase and volcanic material to laumontite can proceed throughout this interval, while alteration of heulandite to laumontite generally requires temperatures above 90 °C. High pH, low pCO₂ and Ca-rich pore fluids are key factors controlling laumontite formation, while the presence of Na⁺ lowers the equilibrium temperature of laumontite-forming reactions. Although early-formed laumontite occupies primary pores, it also contributes to compaction resistance. Owing to its well-developed cleavage and large internal pore volume, laumontite dissolves more readily in acidic fluids than K-feldspar, albite, or other aluminosilicates. Its dissolution zone provides a favourable environment for hydrocarbon accumulation.
