Here, we present stable chromium (Cr) isotope data for mafic potassic lavas from the circum-Mediterranean to evaluate sediment redox impacts on the mantle. These lavas display elevated δ53Cr values relative to mid-ocean ridge basalts, indicating mantle metasomatism by melts derived from organic-rich, anoxic sediments. Western Mediterranean lavas show systematically higher δ53Cr values than their eastern counterparts. Crucially, at a given MgO content, western lavas also feature higher Cr concentrations. Because Cr (II) is more incompatible than Cr (III) during mantle melting, these elevated Cr abundances and higher δ53Cr directly demonstrate a more reduced mantle source in the west, driven by a greater mass fraction of subducted anoxic sediments. This mantle fO2 contrast provides an insightful regional redox context for the sparse porphyry mineralization in the west. Chromium isotopes provide a new proxy for tracing sediment recycling and regional porphyry mineralization in convergent margins.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"38 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149022030","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}

Active orogenic regions serve as hotspots of OCpetro oxidation because of high bedrock denudation rates and substantial OCpetro reserves within the crust. However, limited data and proxies have hindered a comprehensive understanding of the temporal evolution of OCpetro oxidation during orogeny. We semi-quantified the OCpetro oxidation intensity and flux in Taiwan, an active orogen in East Asia, since the late Miocene. Raman spectroscopy and organic carbon-nitrogen (including δ13C and ratio of C/N) were employed to analyze OCpetro in abyssal sediment deposited in the northern South China Sea. The OCpetro oxidation intensity was higher than 50% before 3 Ma, while it sharply declined from ∼50% to ∼20% over the past 3 m.y. Conversely, the OCpetro oxidation flux rose from 0.12 ± 0.03−0.19 ± 0.04 Mt/yr before 3 Ma to 0.23 ± 0.04−0.35 ± 0.07 Mt/yr after 3 Ma. The accelerated uplift of the Taiwan orogen increased erosion rates, which shortened the residence time of OCpetro in the weathering zone and increased the supply of OCpetro for oxidation. As a result, the OCpetro oxidation pattern in Taiwan transitioned from “less supply with high oxidation intensity” to “more supply with low oxidation intensity.” Combined with the flux of the biosphere-immobilized OC, Taiwan transformed from an OC source to a sink during the orogeny. Our study highlights the significant influence of orogenic activity on the preservation and oxidation of OC.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"9 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149022165","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}

Of the globally deposited locations that express the LJE, exceptionally high δ13Ccarb values (up to +28‰) in the Nash Fork Formation in Wyoming (United States) have been interpreted as evidence for extreme organic carbon burial and possible atmospheric O2 overshoot during the Great Oxidation Event (GOE; ca. 2.4 Ga). We present new high-resolution, phase-specific isotope data from shallow-water dolostones of the Nash Fork Formation. In the basal 22 m, δ13Ccarb values vary from 21.9‰ to 30.5‰ with no systematic stratigraphic trends, and exhibit texturally controlled heterogeneity of up to 5‰ at sub-decimeter scale. Up section, both the magnitude and spatial variability of δ13Ccarb values decrease, despite consistent shallow-water peritidal carbonate facies. These patterns are inconsistent with a well-mixed global carbon reservoir and instead indicate strong local controls on dissolved inorganic carbon composition. We interpret these extreme and heterogeneous δ13Ccarb values to reflect microbial carbon cycling dominated by methanogenesis during the LJE, rather than exceptionally high rates of global organic carbon burial. Subsequent dampening of both δ13Ccarb values and variability within similar facies may reflect a secular increase in the contribution of oxic respiration across the GOE.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"38 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149022166","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, geological evidence of high-temperature coseismic processes recorded in such fault rocks suggests that mechanisms capable of reducing the effectiveness of thermal pressurization have also operated. Here, we report coseismic dilatancy in foliated gouge from the Yangsan fault, a large strike-slip fault in southeastern Korea, and discuss its implications for thermal pressurization efficiency and fluid redistribution. Our observations include gouge injection structures (IV type) penetrating into the surrounding rock, foliation opening structures (F type) within the gouge, and calcite aggregates precipitated within these structures. The IV type is interpreted to record coseismic extension fracturing of the surrounding rock under fault-parallel dynamic tension, whereas the F type is inferred to reflect the opening of foliation driven by thermal pressurization. The formation of these structures may have caused a rapid drop in fluid pressure, potentially diminishing the effectiveness of thermal pressurization and promoting fluid redistribution. Our findings suggest that gouge foliation, while acting as a fluid flow barrier that promotes thermal pressurization, may simultaneously serve as a mechanically weak plane that, once opened during seismic slip, reduces its efficiency by providing a pathway for fluid flow. Notably, the postseismically precipitated calcite aggregates within these coseismic opening structures may represent promising targets for directly constraining the timing of past seismic slip using U-Pb or U-series dating.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"138 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148895334","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 results indicate that elevations of ∼3.2−4.7 km were already established along the Gangdese arc between ca. 77 Ma and 59 Ma, prior to the India−Eurasia collision.

Although climate models predict a humid low-latitude eastern Pangean margin, widespread red-bed records indicate extreme seasonal oxidation, creating a conspicuous “model-sediment” paradox. Located directly on this margin, the Xilinhot-Songliao block captures a “red-gray-red” sedimentary cycle that physically toggled between these conflicting arid and humid states. Here, we report ca. 315 Ma high-quality paleomagnetic data from the block to reconstruct its full drift trajectory (315−265 Ma). Integrated with geological proxies, the block is inferred to have maintained a close tectonic affinity with the Pangean margin initially (ca. 315 Ma), hosting megamonsoon-dominated red beds. Following the expansion of the Hegenshan Ocean to a N-S width of ∼2300 km by ca. 300 Ma, the block underwent “tectonic decoupling,” transitioning into a stable zonal climate depositing pure carbonates. Subsequent reattachment to the supercontinent (280−265 Ma) triggered a rapid reversion to arid megamonsoonal conditions. Occurring under a constant global icehouse, this “red-gray-red” oscillation demonstrates that tectonic distance to the supercontinent acted as the primary switch modulating land-sea thermal feedback.

While the central-southern segment exhibits well-developed oceanic spreading, the tectonic regime of the northern Red Sea remains uncertain, specifically whether it still undergoes continental extension or has already transitioned to oceanic spreading. Thick sediment cover in the northern segment conceals direct evidence of oceanic crust formation. To address this, we examined the spatiotemporal distribution characteristics of more than10,000 earthquakes from a standardized International Seismological Centre (ISC) catalog (1960−2024). We found that seismicity is focused in a narrow zone along the Red Sea axis, and that the activity is overwhelmingly dominated by earthquake swarm sequences focused at distinct zones along the spreading axis. This pattern is typical of other (ultra)slow oceanic spreading centers globally, contrasting with the wider main shock−aftershock behavior expected in continental rifts. Furthermore, the seismological characteristics, including the spatial distribution of earthquakes, the typical swarm activity, and the overall b values, are comparable between the northern and central-southern segments of the Red Sea. We further found that earthquake swarms repeatedly occur in spatial association with bathymetric deeps, confirming these are active volcanic centers. This observation is also valid in the northernmost deeps despite the lack of exposed basaltic crust. Our comprehensive seismic analysis strongly supports the conclusion that active oceanic spreading extends along the entire length of the Red Sea.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"31 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148415613","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}
