Understanding the interactions between surface and deep Earth processes is important for research in many diverse scientific areas including climate, environment, energy, georesources biosphere. The TOPO-EUROPE initiative of International Lithosphere Program serves as a pan-European platform integrated sciences, synergizing observational studies structure fluxes on all spatial temporal scales with modelling processes. This review provides survey developments our quantitative understanding coupled surface-deep achieved through TOPO-EUROPE. most notable innovations include (1) process-based connection upper mantle dynamics absolute plate motion frames; (2) models sediment source-to-sink dynamics, demonstrating importance mass transfer from mountains to basins basin basin; (3) demonstration key role polyphase evolution sedimentary basins, impact pre-rift pre-orogenic structures, subsequent lithosphere landscape dynamics; (4) improved conceptual back-arc extension tectonic inversion onset subduction; (5) explain strength Europe's lithosphere; (6) concepts governing interplay thermal stress-induced intraplate deformation; (7) constraints record vertical motions high-resolution data sets obtained geo-thermochronology topographic evolution; (8) recognition quantifications forcing by erosional and/or glacial-interglacial regional magmatism, major implications carbon cycle geological timescales emerging field biogeodynamics; (9) insights coupling domain geothermal energy exploration. Concerning future agenda TOPO-EUROPE, we also discuss rich potential further advances, multidisciplinary community building across frontiers, biosphere, climate energy. These will focus obtaining better insight into initiation subduction systems, plumes continental rifting (super)continent break-up, deformation reactivation cratons; interaction geodynamic, processes, such glaciation, sea level change processes; sensitivity, tipping points, spatio-temporal tectonics well rock melting outgassing affecting interactions; biogeodynamics, that – life Earth; tightening societal challenges regarding renewable georesources, change, natural geohazards, novel process-understanding system.

Ultrahigh-precision noble gas isotope analyses reveal pervasive subsurface fractionation in hydrothermal systems

Science Advances, Год журнала: 2023, Номер 9(15)

Опубликована: Апрель 14, 2023

Mantle-derived noble gases in volcanic are powerful tracers of terrestrial volatile evolution, as they contain mixtures both primordial (from Earth’s accretion) and secondary (e.g., radiogenic) isotope signals that characterize the composition deep Earth. However, emitted through subaerial hydrothermal systems also contributions from shallow reservoirs (groundwater, crust, atmosphere). Deconvolving source is critical for robust interpretations mantle-derived signals. Here, we use a novel dynamic mass spectrometry technique to measure argon, krypton, xenon isotopes gas with ultrahigh precision. Data Iceland, Germany, United States (Yellowstone, Salton Sea), Costa Rica, Chile show subsurface fractionation within globally pervasive previously unrecognized process causing substantial nonradiogenic Ar-Kr-Xe variations. Quantitatively accounting this vital accurately interpreting nitrogen) signals, profound implications our understanding evolution.

Deep magma degassing and volatile fluxes through volcanic hydrothermal systems: Insights from the Askja and Kverkfjöll volcanoes, Iceland

Mantle volatiles are transported to Earth's crust and surface by basaltic volcanism. During subaerial eruptions, vast amounts of carbon, sulfur halogens can be released the atmosphere during a short time-interval, with impacts ranging in scale from local environment global climate. By contrast, passive volatile release at originating magmatic intrusions is characterized much lower flux, yet may outsize eruptive quantities over long timescales. Volcanic hydrothermal systems (VHSs) act as conduits for such degassing used gauge contribution intrusive magmatism cycles. Here, we present new compositional isotopic (δD δ18O-H2O, 3He/4He, δ13C-CO2, Δ33S-δ34S-H2S SO4) data thermal waters fumarole gases Askja Kverkfjöll volcanoes central Iceland. We use together magma modelling mass balance calculations constrain sources VHSs assess role volcanic emission budgets The CO2/ΣS (10−30), 3He/4He (8.3–10.5 RA; relative air), δ13C-CO2 (−4.1 −0.2 ‰) (−0.031 0.003 ‰ −1.5 +3.6‰) values high-gas flux fumaroles (CO2 > 10 mmol/mol) consistent an origin CO2 S Kverkfjöll. demonstrate that deep (0.5–5 kbar, equivalent ∼2–18 km crustal depth) decompression Iceland results fluxes 330–5060 6–210 kt/yr, respectively, which sufficient account estimated Icelandic (3365–6730 kt/yr), but not VHS (220–440 kt/yr). Secondary, crystallization-driven maturing leaching rocks suggested additional S.

These suggest bulk supplied intrusive, magmatism, largely vented fields.

Noble Gas Isotopes and Nitrogen Isotopologues Reveal Deep Sources and Subsurface Fractionation in Yellowstone Gases

Nitrogen plays a critical role in maintaining Earth's hospitable surface environment over geological time. Despite our atmosphere being dominated by nitrogen, understanding of how nitrogen was delivered to Earth and subsequent planetary processes modified budget through time is currently lacking. Here, we report measurements isotopologues N2 (Δ30), along with ultrahigh precision Ar, Kr, Xe isotopes, hydrothermal gas samples from Yellowstone National Park. We show that δ15N variations are correlated nonradiogenic isotope ratios, indicating groundwater-derived noble gases fractionated the same process as they diffuse rising column magmatic CO2. Notably, similar correlation exists regardless degree atmospheric contamination, suggesting mantle source (i.e., ∼0‰). Two component mixing models between Δ30 demonstrate N2/36Ar (5.3 ± 0.7 × 105) 36Ar/130Xe (1611 212) lower greater than MORB source, respectively, contrary previous findings, plume has not been more efficiently overprinted addition N2- Xe-rich recycled material. Conversely, suggest similarity chondritic meteorites indicates deep reflect composition material initially formed Earth.
