Sulfide minerals are semiconductors and can convert thermal to electrical energy. However, regardless of the high-temperature difference (up to 400 °C) between vent fluids and seawater, the significance of thermoelectric power generation by chimneys is poorly understood. We measured the electrical conductivity and thermoelectromotive force (TEMF) of typical sulfide minerals and each part of zoned chimney walls from seafloor hydrothermal vents to evaluate their thermoelectric conversion. Young and porous chimneys consist mainly of fine-grained sulfate and Zn sulfide, with extremely low electrical conductivity, resulting in no thermoelectric conversion. In contrast, mature chimneys with inner walls rich in Cu, Fe, and Pb sulfides are n-type semiconductors with a high thermoelectric conversion performance. Given a temperature difference of 200−300 °C between the vent fluids and ambient seawater, the TEMF of the mature chimneys approaches 10−210 mV, which is comparable to the redox potential between vent fluids and seawater (∼500 mV). This TEMF could play an essential role as a power source to overcome the overpotential required for the redox reactions at both sides of the chimney walls. Our findings suggest that seafloor chimneys are a unique self-organized thermoelectric conversion system that supplies substantial electrical energy to deep-sea ecosystems.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"21 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145947287","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}

They have been crucial in revealing past changes in annual precipitation (AP), and their presence in water-limited arid regions is used as direct evidence for past wetter climates.

A regionally specific AP-based minimum of 300−350 mm yr−1 has been applied but has not been widely tested and does not explicitly consider other important factors (temperature, evaporation, and topography). Here, we combine field observations of speleothem deposition with logistic regression (LR) and random forest (RF) statistical models to identify the climatic constraints controlling the modern distribution of active and inactive speleothems over a broad geographic region (SW Asia). Using a suite of climatological information related to precipitation, evaporation, temperature, and topography, LR shows that as AP increases, so does the probability of speleothem deposition. However, there is no clear threshold at which speleothem deposition is more likely. This shows a single parameter value cannot be used to determine speleothem deposition across the region. RF combines the effects of several climate metrics to predict areas of active speleothem deposition in SW Asia.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"35 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145947288","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}

Here we apply the thallium (Tl) isotope redox proxy to samples stratigraphically below the ca. 810-million-year-old (Ma) Bitter Springs Carbon Isotope Excursion and spanning the interval between the two Snowball Earth glaciations (ca. 662−650 Ma) to constrain the evolution of Neoproterozoic bottom water redox conditions. Thallium isotopes can be used to reconstruct the global extent of oxygenated oceanic bottom waters because the primary control on seawater Tl isotope compositions (ε205Tl) over million-year time scales is changes in the amount of 205Tl removal by Mn oxides on the seafloor. Samples spanning an ∼20-m.y. period preceding the Bitter Springs excursion from the Tonian Reefal Assemblage (n = 18/30) yield ε205Tlauth values lower than global oceanic inputs (ε205Tl ∼−2‱), with some samples approaching the modern seawater ε205Tl value of −6‱. These sustained low ε205Tlauth values require enhanced burial of Mn oxides elsewhere on the seafloor, which we interpret as evidence for the oxygenation of the deep ocean in the Tonian. In contrast, the majority of samples from the Cryogenian Hay Creek Group (n = 13/16) yield ε205Tlauth values similar to global oceanic inputs, suggesting that the deep ocean was not ventilated at this time. This indicates that Earth’s deep ocean was not gradually oxygenated throughout the Neoproterozoic, but rather experienced intervals of increased and decreased O2 concentrations.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"37 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145894959","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 scarcity of blueschist- and eclogite-facies metamorphism from the Archean rock record indicates either that subduction was not operative or that the evidence has somehow been destroyed. We report an eclogite-facies mineral association (phengite + kyanite + rutile) preserved, with quartz, as inclusions within garnet porphyroblasts in a putative metasedimentary rock from the Lewisian Gneiss Complex in northwest Scotland, part of the North Atlantic craton. In situ Lu−Hf dating of garnet constrains eclogite-facies metamorphism to the Mesoarchean to Neoarchean transition at 2.81 ± 0.04 Ga. Phase equilibrium modeling, Zr-in-rutile thermometry, and phengite barometry constrain pressures (P) to 1.5−2.5 GPa and temperatures (T) to 580−660 °C, corresponding to thermobaric ratios (T/P) between 230 °C/GPa and 440 °C/GPa, markedly cooler than recorded by metamorphic rocks of a similar age elsewhere. The low T/P ratios may provide an early record of the transition from some pre-plate tectonic regime to one with an increasing role for stable subduction, and which ultimately became plate tectonics. This transition reflects thickening and strengthening of the lithosphere, the inevitable long-term consequence of secular cooling of the mantle.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"22 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145894960","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}

Many channels and moats worldwide share significant sedimentary and stratigraphic complexity along with time-scale variability. Prominent shifts in morphology translate to shifts in stacking pattern through both space and time. Contourite channels evolve from subtle depressions on a terrace, with a predominantly aggradational sedimentary stacking pattern, to narrow and deep moats in both aggradational and progradational configurations with incision and infill phases. Moreover, shifts in facies distribution reflects evolutionary changes within and along channels and moats. These variations depict a long-term transformation from weaker to stronger bottom currents, punctuated by millennial and sub-millennial periods of intermittent activity. These are driven by diverse oceanographic and tectonic processes that govern bottom current dynamics and sediment supply. We illustrate these concepts based on the Pliocene−Quaternary channels and moats along the northern middle slope of the Gulf of Cádiz (along the southwestern Iberian Peninsula). There, the margin paleo-morphology, in particular the presence of canyons, affects the evolution of channels and moats due to short-term intermittency and variations of the Mediterranean Outflow Water. Our study offers new perspectives on contourite depositional systems; in particular, our understanding of channels and moats and their potential role in CO2 storage—impacting the twenty-first−century energy transition.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"29 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145847130","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}

Yet, whether early-formed subsolidus garnet persists or breaks down when melting begins remains an open question. Here, we integrate 3-D X-ray tomography with high-resolution major- and trace-element mapping of centrally sectioned garnets across a metapelitic metamorphic sequence to track their response from the subsolidus-suprasolidus transition to melting temperatures up to ∼770 °C. Contrary to experimental and phase equilibrium predictions, garnet undergoes extensive dissolution at the onset of partial melting, losing &gt;40% of its volume. Melt percolation creates internal cavity networks within garnet, connecting crystal interiors to the reactive matrix, markedly shortening intracrystalline diffusion pathways at the melt-crystal interface. This process leads to the consumption of garnet and results in major- and trace-element redistribution at temperatures too low for intracrystalline diffusion in larger grains. Our findings reconcile the long-standing discrepancy between predicted progressive garnet growth above the solidus and the scarcity of melt inclusions in garnet rims in migmatites and granulites. As partial melting begins, subsolidus garnet reacts and becomes a permeable heavy rare earth elements and yttrium (HREE-Y) reservoir in the residual crust.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"8 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145847132","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}

Yet, the cumulative character of plutonic carbonatites and the rapid posteruptive alteration of volcanic carbonatites impede a direct determination of the melt compositions crystallizing these rocks. This study focused on sodium in carbonatite melts, a critical component for their genesis, magmatic evolution, and also for REE mobility, given that most carbonatite-hosted REE mineralizations are formed by alkali-rich fluids. Through experiments at subvolcanic conditions (100−200 MPa, 800−1000 °C), we determined the partition coefficient of Na between apatite and carbonatite melt, DNaapatite/carbonatite, which is rather uniformly 0.010 ± 0.003 at temperatures ≥800 °C. Applying our DNaapatite/carbonatite value to natural samples yields 8−22 wt% Na2O for the melts forming calcic carbonatites and 26−32 wt% Na2O for melts forming dolomite carbonatites. The latter are hence more evolved than calcic carbonatite melts, increasing their potential to shed alkali-rich fluids. A model accounting for calcite fractionation from calcite carbonatite melts prior to apatite saturation indicates primary Na2Omelt contents of 16−23 wt% at 900 °C and 9−11 wt% at 1100 °C, consistent with formation by liquid immiscibility from alkaline silicate magmas, but inconsistent with direct mantle derivation, in particular for dolomitic melts.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"56 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145807416","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}

While machine learning approaches have been increasingly applied to mineral prospectivity, many fail to explicitly incorporate key geological constraints, limiting their capacity to resolve the nonlinear and directionally dependent nature of mineralizing systems. Here we present a geologically constrained data-driven method that explicitly accounts for the spatial non-stationarity and anisotropy in ore-forming processes. In the benchmark case study from Canada, our method demonstrates a 7.4% improvement in recall performance compared with existing models. This robust performance is also observed in applications to the southern Cordillera region. Furthermore, the method elucidates regional ore-forming controls and quantifies spatial anisotropy in porphyry copper systems. Our findings demonstrate that incorporating geological constraints into data-driven models enhances both the accuracy and interpretability of mineral prospectivity assessments, offering a robust path forward in resource exploration.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"23 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145807827","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}

We address this by examining a ∼160-m-long section of the East Anatolian fault surface rupture of the Mw 7.8 2023 Kahramanmaraş strike-slip earthquake (Turkey). The rupture offsets meter-spaced ridges and furrows in a ploughed field, providing a unique opportunity for detailed displacement measurements, which were obtained from an orthophoto and a digital elevation model (DEM) built for this study. The surface rupture consists of ten primary segments separated by nine restraining stepovers and is associated with a 3-D strain field dominated by ∼3.5 m of left-lateral offset. Displacement patterns allow us to derive a new model for strike-slip fault growth in which deformation is asymmetric and controlled by the 3-D structure of the fault—specifically, by the position of the underlying fault relative to shallow fault segments. Initially, displacement is accommodated by contraction within restraining stepovers. With increasing displacement, fault segments located closer to the trace of the underlying fault consistently accumulate greater displacement. This asymmetry is facilitated by enhanced synthetic rotation within stepovers. With further displacement, the higher-displacement segment bounding a stepover becomes dominant, while the other one is bypassed and layer rotation ceases. These results not only improve fault growth models but could also inform seismic hazard models and impact industrial applications dealing with subsurface faulted reservoirs.","PeriodicalId":12642,"journal":{"name":"Geology","volume":"36 1","pages":""},"PeriodicalIF":5.8,"publicationDate":"2025-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145807417","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}
