Unlike other beryl, it contains high U (tens to thousands of parts per million). This study provides U-Pb dates for red beryl crystallization from five localities in three ranges, yielding robust laser ablation−inductively coupled plasma−mass spectrometry (LA-ICP-MS) dates at higher precision than coeval sanidine K-Ar and zircon fission-track dates. U-Pb dates for specimens from the Ruby Violet Claim (20.96 ± 0.23 Ma) of the Wah Wah Mountains, Utah, Snowflake Claim (24.96 ± 0.3 Ma) of the Black Range, New Mexico, and Searle Canyon (6.69 ± 0.12 Ma) and Maynard’s Claim (6.87 ± 0.11 Ma) in the Thomas Range, Utah, are compatible with prior regional age constraints. However, red beryl dates from Wildhorse Spring, Utah (22.34 ± 0.20 Ma), are older than the expected age of ca. 6 Ma. These data reassign the red beryl−bearing layer to Spor Mountain volcanism, the host to the world’s largest Be deposit, indicating that a wider region should be explored for Be mineralization. Red beryl provides direct age limits on outgassing, capturing very late-stage volcanic processes not recorded by common geochronometers, which typically form within magma chambers or during eruptions. Our results show that if red beryl, a gem, or other unusual minerals have elevated U, they should be targeted as possible geochronometers.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"263 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209696","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}

Using numerical simulations of mantle convection with melting and dehydration-dependent rheology, we show that convective thinning drives decompression melting, generating contrasting density and viscosity, strain localization, and porosity gradients within the lithosphere. Subsequent deformation (with imbrication and tilting) and cooling freeze the lithosphere into a three-layer structure: a paleo-thermal boundary layer, a compositionally modified layer, and a thermal sublayer. These features explain observed geophysical properties and reproduce seismic velocity gradients across MLD interfaces, though matching the full contrasts likely requires additional fluids/melt retention. This mechanism operates across the full range of mantle temperatures, from Archean to present-day conditions, providing a unified explanation for the abundance of MLDs in cratons, decreasing prevalence with secular cooling, and persistent occurrence in modern lithosphere on Earth and other planets.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"4 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209699","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}

Aillikite δ41K ranges from −0.62‰ to −0.31‰ and correlates positively with εHf, indicating mixing between distinct mantle reservoirs rather than magmatic differentiation. The data can be reproduced by mixing a K-poor, high-δ41K carbonatitic melt with a K-rich, low-δ41K CLM metasome characterized by unradiogenic Hf. We infer a two-stage evolution in which CO2-rich melts formed in the asthenosphere from domains containing recycled carbonate-rich oceanic material and then acquired their potassic compositions and decoupled Nd-Hf isotope signatures during ascent through heterogeneous CLM. The Nd-Hf isotope decoupling in aillikites and kimberlites therefore records interaction between deep CO2-rich melts and ancient CLM domains.

We document active normal-sense faulting on Chirikof Island within the Semidi segment that lies between the contrasting plate-interface behavior and upper-plate deformation styles of the Kodiak and Shumagin segments. Geomorphic and geochronologic data indicate 4−9 m of cumulative slip and that fault-scarp development continued after ca. 6 ka, with evidence suggesting multiple episodes of fault reactivation. Bedrock structures and thermochronologic data indicate that this normal faulting represents a recent shift from prolonged shortening to extension in this part of the forearc. This deformation change coincides with the along-strike transition from persistent thrusting in the Kodiak segment to large-scale normal faulting in the Shumagin segment. We propose that variations in subducting-plate fabric orientation and inherited seafloor heterogeneities may influence plate-interface mechanics and the stress state of the upper plate, potentially contributing to the contrasting deformation styles.

We report Hm (U-Th)/He (HHe) and Gt (U-Th)/He (GHe) dates to and thermal inversions of karst bauxites from Provence (France).

HHe systematically yields older ages (85−22 Ma) than coexisting GHe (32−12 Ma), reflecting higher He retentivity. Hm (U-Th)/He thermal modeling, consistent with regional geology, reveals two thermal events: (1) heating to 90−120 °C until 60−45 Ma during Pyrenean compression, followed by cooling; and (2) reheating to 50−60 °C between 35 Ma and 15 Ma during the onset of the West European Rift, which partially reset HHe.

Despite the abundance and antiquity of submarine basalts, the fossil record of this deep igneous habitat is sparse and controversial. Here we report the presence of filamentous microstructures in drill-core samples (drill depth 610 m) of vesicular submarine basalts intercalated with the 2.46 Ga Kuruman Iron Formation, in Griqualand West, South Africa. A network of sinuous and uniformly thick filaments, which are lined by fine-grained Fe-rich phyllosilicates, is preserved in calcite- and stilpnomelane-cemented vesicles near the top of the flow. Based on their uniform size, regular shape, and similarity to putative microfossils in younger vesicular basalts, the filaments are interpreted to be relicts of cavity-dwelling (cryptoendolithic) microbes that were mineralized by Fe-silicate clays and encased in calcite cement shortly after basalt eruption. Our results suggest that ancient basaltic lavas were rapidly colonized by microbes in a thermally and geochemically active environment that today is occupied by chemoautotrophs and heterotrophs. The findings confirm submarine lavas as a habitat for early life, and extend the antiquity of basalt-hosted cryptoendoliths, hinting at a lengthy fossil record for the deep igneous biosphere.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"37 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091301","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}

Alkaline lakes are among the few modern environments hydrochemically conducive to low-temperature dolomite formation. However, the nucleation and growth of dolomite under alkaline conditions, and how these processes are related to alkaline water chemistry, remain poorly understood. We report extensive dolomites recently observed in the lower Permian Fengcheng Formation of the Junggar Basin (northwest China); well-preserved ancient alkaline deposits. High-resolution, in situ secondary ion mass spectrometry (SIMS)−based carbon and oxygen isotope analyses reveal systematic zonation in dolomite crystals: δ18OVPDB (VPDB—Vienna Peedee belemnite) decreases from the core (3.30‰) to the intermediate (0.35‰) rim (−11.12‰), whereas δ13CVPDB increases from the core (0.89‰) to the intermediate (4.74‰) rim (6.81‰). The positive δ18O values of the core zone, together with its finely preserved nucleus and radial cathodoluminescence (CL) textures, suggest syndepositional nucleation under intensive evaporative conditions. The opposing core-to-rim trends in δ13C and δ18O of the studied dolomites capture the progressive evolution of the dolomites, with increasing formation temperatures and intensifying methanogenesis, from initial nucleation in the evaporative water column through growth near the sediment−water interface to final overgrowth in the burial methanogenesis zone. Our results suggest that alkaline lake conditions can promote the direct nucleation of dolomite via an inorganic pathway, providing important constraints on the role of alkaline environments in resolving the long-standing “dolomite problem” in abiotic systems.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"6 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091302","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 exact relationship between microbial processes, iron deposition, and stromatolite growth remains murky. Here we show that stromatolites in 1.88 Ga iron formations (Sokoman Formation) from the Labrador Trough, Canada, comprise laminae of dusty chert interbedded with dusty chert clasts and sand-sized Fe-silicate grains. High-resolution transmission electron microscopy and analysis show that the dust particles comprise nanometer-sized crystals of greenalite and apatite. The presence of clasts of dusty chert that closely resemble surrounding laminated chert suggests that they are rip-up clasts, indicating penecontemporaneous silica cementation of greenalite-rich muds. Our observations suggest that the stromatolites grew during tranquil conditions by microbial trapping and binding of suspended nanoparticles accompanied by in situ silica precipitation. Our results also provide potential insights into the origin of granular iron formations, suggesting a link between the deposition of greenalite nanoparticles and the production of Fe-silicate grains by accretion on muddy substrates or erosion of silica-cemented greenalite muds. We speculate that greenalite nanoparticles were not only a major primary phase in banded iron formations (e.g., Hamersley Group, Western Australia) but also an important building block of granular iron formations, representing a key ingredient in the formation of sand-sized grains during sedimentary reworking in high-energy, shallow-water environments.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"9 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091303","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, halogen compositions and budgets of cratonic roots remain poorly constrained. We present halogen (F, Cl, Br, I) data of intraplate alkaline rocks from Aillik Bay, Labrador, eastern Canada, that originate from melting of an evolving cratonic root during three distinct time periods: Mesoproterozoic lamproites, Neoproterozoic ultramafic lamprophyres including aillikites and carbonatites, and Cretaceous nephelinites. Compared to mid-ocean ridge basalts (MORBs), lamproites and lamprophyres show higher F (1200−6040 ppm) and Br/Cl ratios (3.3−30.0 × 10−3), which are inconsistent with a degassing signature and instead reflect enrichment of F and Br in their mantle sources. In contrast, nephelinites have high F (1470−2430 ppm) but MORB-like Br/Cl ratios (1.3−2.4 × 10−3), consistent with Br loss during fluid exsolution. These results agree with published halogen data for carbonatites, kimberlites, inclusions in diamonds and cratonic peridotites, showing that cratonic roots worldwide are enriched in F and Br. Our estimates indicate that the cratonic root hosts ∼3.7 ± 0.8 × 1017 kg F (1sd), 1.3 ± 0.4 × 1016 kg Cl (1sd), and 1.9 ± 0.9 × 1014 kg Br (1sd), whose rapid release (generally &lt;5 m.y.) through large igneous province magmatism during mantle plume-cratonic root interaction may have triggered severe ozone depletion and environmental crises.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"92 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149091304","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}
