Abstract Submarine volcanism represents ~80% of the volcanic activity on Earth and is an important source mantle-derived gases. These gases are basic importance for comprehension mantle characteristics in areas where subaerial missing or strongly modified by presence crustal/atmospheric components. Though, study submarine remains a challenge due to their hazardousness sea-depth. Here, we report 3 He/ 4 He measurements CO 2 –dominated discharged at 500 m below sea level from high-temperature...
Identifying the origin of noble gases in Earth's mantle can provide crucial constraints on source and timing volatile (C, N, H2O, gases, etc.) delivery to Earth. It remains unclear whether early Earth was able directly capture retain volatiles throughout accretion or it accreted anhydrously subsequently acquired through later additions chondritic material. Here, we report high-precision gas isotopic data from volcanic emanating from, around, Yellowstone caldera (Wyoming, United States). We...
The terrestrial carbon to nitrogen ratio is a key geochemical parameter that can provide information on the nature of Earth's precursors, accretion/differentiation processes our planet, as well volatile budget Earth. In principle, this be determined from analysis elements trapped in mantle-derived rocks like mid-ocean ridge basalts (MORB), corrected for fractional degassing during eruption. However, correction critical and previous attempts have adopted different approaches which led...
The Near Fault Observatories (NFOs) community is one of the European Plate Observing System (EPOS, http://www.epos-eu.org) Thematic Communities, today consisting six research infrastructures that operate in regions characterised by high seismic hazard originating from different tectonic regimes. Earthquakes respond to complex natural systems whose mechanical properties evolve over time. Thus, order understand multi-scale, physical/chemical processes responsible for faulting earthquakes occur...
This study is focused on fluids characterization and circulations through the crust of Irpinia region, an active seismic zone in Southern Italy, that has experienced several high-magnitude earthquakes, including a catastrophic one 1980 (M = 6.9 Ms). Using isotopic geochemistry carbon‑helium system free dissolved volatiles water, this aims to explore processes at depth can alter pristine chemistry these natural fluids. Gas-rock-water interactions their impact CO2 emissions composition are...
The Betic Cordillera, located in southeastern Spain, underwent a complex geodynamic history that contributed to the Messinian salinity crisis Mediterranean. Alboran margin is characterized by crustal thinning, linked slab retreat, tearing, and delamination processes during Miocene. These processes, combined with alkaline calc-alkaline volcanism exhumation of metamorphic domes, are thought drive dynamic fluid system. relative contributions magmatism, thinning tearing uplift Betics remain...
Mud volcanoes represent the largest expression of natural methane release into atmosphere; however, gas flux has never been investigated in detail. Methane output from vents and diffuse soil degassing is herewith reported for first time. Measurements were carried out at 5 mud volcano fields around Sicily (Italy). Each characterized by tens bubbling pools. In quiescent phase, emission single ranges between 0.01 6.8 kg/day. Diffuse leakage order 10 2 –10 4 mg m −2 d −1 . An exceptional 6 was...
[1] Molecular composition, CH4 isotopes and gas flux of all main terrestrial mud volcanoes other methane seeps in Italy are being assessed for the first time. Whereas 74% Italian reservoirs biogenic, about 80% release thermogenic gas. Dry-seep generally maintains reservoir C1/(C2 + C3) "Bernard" ratio while show molecular fractionation likely occurring during advective migration. Accordingly, a simple direct use parameter might be misleading when applied to as it could not always reflect...
Studies of submarine hydrothermal systems in Mediterranean Sea are limited to the southern Italian volcanism, while totally missing Aegean. Here we report on geochemistry high-temperature fluids (up 220°C) venting at 500 m b.s.l. from floor Kolumbo volcano (Hellenic Volcanic Arc, Greece), which is located 7 km northeast Santorini Island. Despite recent unrest Santorini, considered more active due a higher seismicity. Rizzo et al. (2016) investigated He-isotope composition gases collected...
Abstract In order to investigate the variability of helium degassing in continental regions, its release from rocks and emission into atmosphere, here we studied volatiles a seismically active region northern Italy (Mw MAX = 6) at Nirano-Regnano mud volcanic system. The emitted gases study area are CH 4 –dominated it is carrier for (He) transfer through crust. Carbon He isotopes unequivocally indicate that crustal-derived fluids dominate these systems. An high-resolution 3-dimensional...
Abstract Deep fluids play active roles during the preparatory phases of large earthquakes and, through their chemical signature, carry information about deep processes within seismogenic crust. Due to its inertness and isotopic helium (the lightest noble gas) is a useful tracer for investigating storage transfer crust, including those prior hazardous earthquakes. Here we analyse 12-year earthquake catalogue from Irpinia Fault Zone, Italy, compute 4 He outputs seismogenetic fault zones (from...
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...
A petrological and geochemical study was performed on 5 selected samples of peridotites from two different sites (Finero Balmuccia) outcropping in the Ivrea Verbano Zone, with aim to investigate processes occurring deep lithosphere possible interaction lower crust.The Finero area fall harzuburgite (FIN1, FIN3, FIN4) field whereas those Balmuccia are lherzolithes (BALM1) werlhites (BALM4), highlighting respectively presence a more fertile primordial mantle for sites.The rocks featured by...
The analysis of fault-related mineralization and, particularly, in the Fluid Inclusions (FIs) entrapped synkinematic minerals are key to assess origin and modalities fluid circulation through fault zones. results these analyses, compared with those focusing on present-day fluids, crucial better understanding processes regulating both paleo modern degassing from Earth’s interior seismicity crustal deformation. In particular, focus is role that deep fluids might have deformation over...
Central Italy is affected by a significant migration of deep CO2 through the crust. upraise gives rise to numerous gas emissions in western Tyrrhenian domain where extensional deformation has dismantled compressional structures, enabling fluid mature set normal faults. Conversely, thickened crust and abundant groundwater circulation carbonate aquifers Apennine “trap” migrating fluids. Here, eastern sector, dissolves large aquifers, while anomalies disappear easternmost...
Assessing leakage mechanisms that compromise reservoir integrity is essential for effective geo-resource management and mitigating environmental risks. Reservoir leakages can occur via both anthropogenic pathways, such as active inactive wells pipelines, natural including fractures fault zones. Additionally, fault-valve action temporarily disrupt sealing layers, allowing trapped fluids to migrate upward. Distinguishing between human-induced causes of valuable but often challenging. To...
Investigating the main geochemical characteristics of lower continental crust is essential to understand its formation and evolution, identifying crustal differentiation processes possible crust-mantle interactions. We performed bulk rock (major trace elements), noble gases isotopes (He, Ne, Ar), fluid inclusions (Raman spectroscopy) analyses on metamorphic rocks from Ivrea-Verbano Zone (Southern Italian Alps). Specifically, we studied various lithologies (metapelite, metagabbro, mafic...
Hydrocarbon leakage from reservoirs poses significant environmental and societal problems, including the potential contamination of drinking water agricultural soils. Distinguishing between natural anthropogenic is challenging but crucial for assessing human impacts on reservoir seal integrity developing effective mitigation strategies. To address this issue, study presents an innovative approach that combines traditional groundwater analyses with fluid inclusion investigation to evaluate...
