This review synthesizes geochemical data from 56,450 volcanic rocks across 29 Cenozoic arcs and 1242 zircon analyses from 6 Mesozoic-Cenozoic arcs worldwide to clarify the roles of source and fractionation processes in shaping arc magma oxidation states, with a focus on distinctions between continental and oceanic arc settings. We assess oxygen fugacity using Fe³⁺/ΣFe ratios of volcanic rocks at varying MgO contents to evaluate the fractionation effects, while Ti, Ce, and initial U contents in zircons provide insights into oxygen fugacity trends in evolved magmas. High-MgO volcanic rocks (MgO &gt; 8 wt%) reflect the redox state of arc magma sources, whereas low-MgO rocks (MgO &lt; 8 wt%) and zircons reveal fractionation influences. Thermodynamic modeling with MELTS and Monte Carlo mass balance simulations of cumulates and residual melts further constrain the impact of crustal thickness, partial melting, and mineral fractionation on magma oxidation. Our findings indicate that primitive magmas (MgO &gt; 8 wt%) in continental arcs exhibit slightly more oxidized (average Fe³⁺/ΣFe = 0.33 ± 0.01, 1σ) than those in oceanic arcs (averaging 0.30 ± 0.01). Oxidation increases with differentiation, reaching Fe³⁺/ΣFe values of 0.55 ± 0.01 in continental arcs and 0.49 ± 0.01 in oceanic arcs at low MgO contents (&lt; 1 wt%). Zircon data confirm rising oxygen fugacity with decreasing temperature, with a steeper trend in continental arcs. Higher slab-derived fluxes, lower degrees of partial melting, and fractionation of minerals such as garnet and amphibole, driven by greater crustal thickness, enhance oxidation in continental arcs. This review emphasizes the critical role of magma differentiation on oxidation of arc magmas and provides a comprehensive framework for understanding arc magma oxidation, highlighting distinct processes in continental and oceanic arcs and identifying key avenues for future research.</div></div>","PeriodicalId":11483,"journal":{"name":"Earth-Science Reviews","volume":"271 ","pages":"Article 105287"},"PeriodicalIF":10.0,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145217920","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}

However, the controls on metallogenic assemblages in post-collisional porphyry deposits remain poorly constrained. The Jinshajiang-Ailaoshan metallogenic belt hosts a suite of Eocene-Oligocene post-collisional porphyry Cu, Au-Cu, and Au deposits, offering an ideal natural laboratory to elucidate the factors controlling the differential enrichment of metal assemblages in post-collisional porphyry mineralization systems. To identify the primary factors controlling the differential enrichment of metallogenic assemblages, over 2500 published whole-rock and mineral geochemical data from mineralization-related porphyries in post-collisional porphyry deposits of the Jinshajiang-Ailaoshan metallogenic belt were compiled and combined with geophysical and thermodynamic modeling results. The results indicate that the parental magmas of mineralization-related porphyries in the Jinshajiang-Ailaoshan metallogenic belt were generated by variable mixing proportions of juvenile lower-crust melts and underlying metasomatized subcontinental lithospheric mantle (SCLM) melts. Our results demonstrate that the degree of magma differentiation, oxygen fugacity, water contents, and crustal thickness progressively decrease as the metallogenic assemblage transitions from Cu to Au-Cu and finally to Au. Magma undergoes prolonged evolution in lower crustal reservoirs (2.19 kbar) beneath thick crust (60–63 km), exhibiting higher degrees of magma differentiation, oxygen fugacity (∆FMQ = 1.79–2.76), and water contents (3.89 wt% H&lt;sub&gt;2&lt;/sub&gt;O), thereby promoting the formation of post-collisional porphyry Cu deposits. However, higher pressure and water contents promote early sulfide saturation, which in turn causes Au depletion through the precipitation of sulfides. Additionally, high oxygen fugacity (∆FMQ &gt; ∼1.00) suppresses Au dissolution in the magma. In contrast, shallow magma reservoirs (&lt; 1.00 kbar) in thinner crust (33–36 km) undergo brief evolution and are characterized by lower degrees of magma differentiation, oxygen fugacity (∆FMQ = 0.78), and water contents (2.91 wt% H&lt;sub&gt;2&lt;/sub&gt;O). Meanwhile, lower pressures and water contents delayed sulfide saturation, favoring Au enrichment and creating conditions conducive to forming post-collisional porphyry Au deposits.

Adakitic and I-type rocks characterize the 266–240 Ma magmatic pulse, whereas 229–210 Ma, 209–185 Ma, and 184–163 Ma magmatic rocks exhibit three distinct suites of adakitic, I-type and A-type rocks.

The petrogenetic history of these rocks, integrated with temporal changes in crustal thickness and evidence from previous studies, suggests that the tectono-magmatic history of the Zhangguangcai Terrane was dominated by the westward subduction and ultimate closure of the Heilongjiang Ocean. Convergent plate interaction occurred from 266 to 210 Ma, leading to prolonged crustal growth and reworking. A magmatic lull at ca. 240–230 Ma is ascribed to low-angle (or flat-slab) subduction of the Heilongjiang oceanic plate. Closure (209–180 Ma) of the Heilongjiang Ocean and obduction of ocean fragments (180–163 Ma) culminated in the final amalgamation of the Jiamusi-Khanka Block with the Central Asian Orogenic Belt, and the tectonic exhumation and emplacement of blueschist in the Heilongjiang Accretionary Complex.

This method enhances the complexity and richness of environmental reconstructions by integrating various proxies, such as testate amoebae, pollen, plant macrofossils, charcoal, and stable isotopes. While synthesising these records can be challenging, due both to their complexity and varying journal guidelines for publication, it remains essential for a more precise understanding of past ecosystems. Multi-proxy studies are invaluable for cross-referencing local to extra-local data with proxies from nearby areas, thus validating palaeoclimatic records and minimising speculative conclusions. The approach reveals significant human impacts on ecosystems, particularly peatlands, serving as natural archives for historical environmental and anthropogenic activities. Integrating diverse methodologies from ecology, palaeoecology, archaeology, and history with high-resolution palaeoecological data offers profound insights into settlement patterns, economic development, and historical demography. Despite the challenges of handling extensive datasets, advanced statistical methods enable meaningful interpretations while maintaining the integrity of the data. Historical records enrich the understanding of human and climatic impacts upon a range of peatland ecosystems. By reconstructing long-term changes in food webs through peat records, researchers can gain a deeper understanding of past ecosystem structures and functions, thereby paving the way for future ecological advances.

Duvernay shales typically contain vertical and sub-vertical calcite veins with light oil inclusions. The compositions and homogenization temperatures of these inclusions indicate that the trapped fluids are more liquid-rich than the produced fluids and were likely trapped under variable overpressures during fracturing.

However, our understanding of the isotopic fractionations in a long record remains elusive, particularly as biocarbonates frequently precipitate out of thermodynamics-based isotopic equilibrium with ambient waters. The knowledge gap arises from the different roles of metabolic and kinetic effects in disequilibrium fractionations, in addition to the impacts of various surface processes in the lake catchment on the input and output of isotopic flux of a lake basin.

The recent discovery of Eocene monsoon-arid climate signatures has reignited debates regarding the spatiotemporal origins and drivers of this system. To resolve these discrepancies, we undertake a synthesis of multi-proxy paleoclimate records from 71 key Eocene sites across China to systematically reevaluate the spatiotemporal evolution of climate patterns in southern, central, and northern China. Our analysis delineates three distinct climatic phases: (1) During the early Eocene, a zonal broad arid-semiarid belt extended across central-southern China (20–40°N), flanked by two humid zones in Hainan Island-southern Tibet (&lt;20°N) and northern China (&gt;40°N), respectively; (2) Subsequently, by the middle Eocene, a humid monsoonal climate advanced northward in southern China (&lt;25°N), while central China remained persistently arid and northern China maintained its humid conditions; (3) During the late Eocene, the humid monsoonal climate in southern China expanded further northward (26–28°N), the eastern part of central China experienced intermittent humid intervals, the western part of central China (northwest China) underwent pronounced aridification, and northern China witnessed a southward expansion of its humid zone into the Bohai Bay Basin. A pivotal climatic reorganization occurred at 41 Ma, characterized by the synchronous intensification of the Asian monsoon in southern China and aridification of the Asian interior, marking the inception of the Asian monsoon-arid system. This study reconciles long-standing inconsistencies by demonstrating that middle–late Eocene humidification in southern China was primarily driven by the intensification of the East Asian (EAM) and South Asian (SAM) monsoons, rather than primarily by latitudinal migrations of the Intertropical Convergence Zone (ITCZ). Central China was predominantly under the influence of subtropical high pressure throughout the Eocene, with episodic monsoonal incursions limited to the late Eocene. Conversely, the hydroclimate of northeast China was predominantly governed by westerlies transporting moisture from the proto-Paratethys Sea, rather than by the EAM. We propose that the evolution of Eocene climate patterns was driven by the combined effects of Tibetan Plateau uplift, the retreat of the proto-Paratethys Sea (a key driver of the climatic shift at 41 Ma), and global cooling.

Two distinct pathways are identified: dissolved CO₂ injection, which produces uniform reaction fronts via bulk transport, and supercritical CO₂ injection, where thin-film interfacial reactions dominate. Fluid chemistry evolution is strongly temperature-dependent, with systematic trends in pH, Ca, Mg, and Fe concentrations, controlling carbonate and clay precipitation. Porosity and permeability changes reflect a dynamic balance between dissolution-driven pore enlargement and precipitation-induced clogging, with field trials generally showing minimal alteration while laboratory studies reveal contrasting outcomes. Reactive transport models highlight the importance of mineralogical heterogeneity, feedbacks, and chemo-mechanical coupling in governing long-term reservoir behaviour.

We find that storm and tsunami deposits each comprise three differing groups. Using these groups, we infer the processes involved in tsunamis, including the formation of a sediment gravity flow as the tsunami flows into the lake; the progression of a dense, cohesionless flow head, or the displacement of the shallow lake water by the tsunami wave. In contrast, storm deposits are inferred to be formed by bedload under an overwash regime or in a dilute flow under full inundation of the coastal lake or lagoon. From these processes, we show that the composition of tsunami deposits is dependent on the environmental setting of the lake or lagoon whereas, for storms, the event size is a greater factor. Our findings show that in most cases, storm events are inherently unable to generate the tsunami deposits found in coastal lakes and lagoons. This insight enables the establishment of recognition criteria and a framework that can be applied to candidate deposits to differentiate unequivocally between the two event types.
