Using a 70-day-long dense deployment of 336 nodal-sensors in 2019, we develop an enhanced seismicity catalog and combine it with focal mechanism solutions, fluid-injection time series, seismic-reflection profiles, and geomechanical models to identify the distinct shallow and deep seismicity responses to HF.

Effective utilization of geothermal resources hinges on identifying or generating permeable reservoir zones and understanding how effective pressure variations affect fluid circulation and reservoir properties by poroelastic deformation. Hydrothermal alteration can modify the petrophysical properties of geothermal reservoir rocks, which may increase or decrease its productivity. Understanding these alteration effects is essential to predict and optimize long-term sustainable geothermal operations. Here, we investigate the impact of hydrothermal alteration on poroelastic and hydraulic properties of diverse lithologies in a series of deformation tests performed at several confining (0–80 MPa) and pore pressure (10–30 MPa) levels. Experimental results of hydrothermally altered dikes and phyllites obtained from the Blue Mountain geothermal field (Nevada, USA) are compared to thermally cracked La Peyratte granite (France) and correlated with petrophysical properties, mineral composition, and microstructures. Argillic alteration of dikes increases porosity and storage capacity but lowers thermal conductivity and increases pore compressibility. Conversely, silicate precipitation in phyllites increases stiffness and thermal conductivity but also reduces porosity and permeability. Experimentally determined effective pressure coefficients range from 0.1 to 0.9, differ for permeability and volumetric strain and decrease with increasing effective pressure. The presence of compliant microcracks and crack-like pores significantly increases the stress sensitivity of La Peyratte granite and silicified phyllites. This study demonstrates how thermal and chemical alteration impacts poromechanical and petrophysical characteristics of geothermal targets, which ultimately govern reservoir stability and subsidence, induced seismicity as well as fluid and heat extraction efficiency during geothermal operations.</p>","PeriodicalId":15864,"journal":{"name":"Journal of Geophysical Research: Solid Earth","volume":"130 4","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2024JB030541","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Troodos ophiolite offers an opportunity to discriminate between different serpentinization processes, incorporating rock magnetism, paleomagnetism and forward modeling of field magnetic data. Our results revealed distinct magnetic property zones: weakly magnetic mantle Artemis and Olympus zones, and a highly magnetic lower crust Cumulate zone. The Artemis and Olympus samples have magnetite concentrations &lt;1%, magnetic susceptibility &lt;0.01 SI and natural remanent magnetization (NRM) &lt;4 A/m, consistent with low-temperature serpentinization related to subduction or meteoric water. In contrast, the Cumulate zone rocks have magnetite content up to 8%, magnetic susceptibility up to 0.1 SI and NRM up to 12 A/m, interpreted as high-temperature serpentinite near a spreading ridge. This ridge-related serpentinization is supported by the paleomagnetic results. The Cumulate zone has a mean direction of <i>declination</i> = 280°, <i>inclination</i> = 69°, <i>α</i>₉₅ = 16°, comparable to the direction of the lower crust gabbro, which suggests serpentinization-associated chemical remagnetization during Cretaceous oceanic crust formation.

The objective was to examine the impact of deposition upslope of the barrier on interactions between debris flows and check dams by combining seismic and dynamic parameters. We found that a frequency domain feature-based method can successfully filter out noisy signals. Results showed that it is possible to distinguish the impact mechanism of a granular flow in the presence of deposition upslope of the barrier from the seismic signals' attributes, that is, the peak signal amplitude envelope before granular flow overflow and its ratio to the peak amplitude of the control test without the barrier. Furthermore, the presence of check dams and upslope deposits in the debris flow channel significantly reduces the sensitivity of seismic signals to flow velocity.

Upon subduction initiation, the maximum depth of slab-mantle decoupling (MDD) is relatively shallow (∼20 km depth), resulting in mantle flow and CPO development in the wedge corner. As subduction continues, the MDD deepens, the wedge corner cools and stagnates, and the olivine CPO becomes frozen-in. In the cool wedge corner, antigorite can form if water is available. In non-deforming mantle, antigorite CPO develops relative to the host olivine CPO through topotactic growth. We calculate splitting parameters of synthetic local S waves based on the model-predicted A- and B-type olivine CPOs and topotactically grown antigorite CPO that replaces A-type olivine CPO in the wedge corner. The fast direction is trench-normal for A-type olivine and antigorite CPOs and trench-parallel for B-type. When the delay times are long enough (&gt;0.1 s), we find them positively correlated with the thickness of the mantle wedge corner. In NE Japan, where the results of detailed analyses on the spatial variation of the SWS parameters are available, such correlation is not observationally reported.

An increase in normal stress increases frictional strength by ∼20% accompanied by many small slip events triggered by grain breakage.

Our results reveal the prevailing coexistence of both Si-OH and Mg/Ca-OH, with the latter arising from charge compensation by the more predominate Mg/Ca-OH₂ species. The incorporation of water constantly disrupts the silicate network by converting the bridging oxygens (BOs) to non-bridging oxygens (NBOs), generating more isolated, diffusible, yet stable silicate clusters (such as monomers or oligomers), with lower coordination numbers, longer species lifetimes and more stretched bond angles. The dissolution of water significantly facilitates the diffusivities of all species, while reducing the shear viscosity. The strong linear correlations between the diffusivities/viscosity and the degree of polymerization underscore the water-induced depolymerization as the primary mechanism driving the high mobility of supercritical fluids. The viscosity contrast between anhydrous and hydrous melts could cause the substantial differences in magma mobility and ascent rates, leading to the diverse radioactive isotope patterns between the melt-source and fluid-source arc lavas.
