“…The fault‐valve behavior, which describes the subsequent co‐seismic enhancement and inter‐seismic reduction of the permeability (Im et al., 2018; Sibson, 1981), is inadequate to explain the continuous activity of hydrothermal springs during long inter‐seismic periods. Evidence of thermal springs, fluids and associated deformation of isotherms in both fault compartments, indicate the occurrence of longitudinal and transverse hydrothermal circulations along reverse faults (Forster & Evans, 1991; Grasby & Hutcheon, 2001; Moretti et al., 2000; Rowe et al., 2009; Smeraglia et al., 2022). Accordingly, we propose that the Calientes and Incapuquio faults may have a permanent and efficient permeability, transversely as well as longitudinally, even during inter‐seismic periods.…”

This study provides a comprehensive characterization of various hydrothermal systems in Southern Peru ranging from the faulted Precordillera's steep topography up to the volcanic High Cordillera (>4,000 m asl). The objective is to investigate thermal anomalies that may potentially serve as new geothermal resources. Our integrated approach combines: (a) geochemistry from 14 hot springs sampled throughout the Tacna region, and (b) 3D numerical modeling of coupled groundwater and heat transfer considering topography and faults embedded in homogeneous permeability. Water and gas analysis indicates that the springs located near volcanoes discharge Na‐K‐Cl waters with high temperatures (>87°C), high Total Dissolved Solid concentrations (TDS >3,452 mg/L), and free gases dominated by CO2 (>90 vol%). Springs located along the regional faults in the Precordillera discharge Ca‐SO4 and Na‐K‐Cl waters with moderate temperatures (27–53°C), intermediate TDS concentrations (464–2,458 mg/L), radiocarbon ages between 1.4 and 7.9 kyr, and free gases dominated by N2 (>95 vol%). The Aruma springs, which are located at the transition between the High and the Precordillera, display intermediate characteristics. Numerical models accurately replicate the locations and temperatures of the fault‐related springs only for permeable faults (>10−14 m2), revealing the creation of 100‐km long thermal plumes along faults, locally rising up the 150°C‐isotherm to about ∼1,000 m below the surface. This approach clearly distinguishes the spring origins, which are volcanic in High Cordillera and tectonic in Precordillera. Moreover, we highlight that steep topographic gradient and permeable reverse faults in the Andean forearc may generate considerable thermal anomalies, opening perspectives for the geothermal exploration.

“…On the contrary, in the uplifted hinterland zones, fluid circulation occurred in an open‐system characterized by the downward infiltration of meteoric‐derived fluids through fault conduits, such as the NE‐SW‐striking strike‐slip faults (Figure 11b). Increasing dominance of meteoric‐derived fluids during increasing contractional deformation was observed in the Albanides fold‐and‐thrust belt (De Graaf et al., 2019; Vilasi et al., 2009), as well in other fold‐and‐thrust belts worldwide (Beaudoin et al., 2022; Fitz‐Diaz et al., 2011; Smeraglia et al., 2022). In the Albanides fold‐and‐thrust belt, faults associated with folding also recorded the mixing between meteoric fluids and evaporite‐derived deep fluids (Swennen et al., 2000).…”

“…In the past decades, several studies focused on fault‐fluid interactions through the structural, geochemical, and geochronological characterization of syn‐tectonic mineralization in specific fault zones pertaining to fold‐and‐thrust belts (Agosta & Kirschner, 2003; Agosta, 2008; Beaudoin et al., 2011; Dennis et al., 2019; Dewever et al., 2013; Huntington & Lechler, 2015; Lacombe & Beaudoin, 2024 for review; Lacroix et al., 2011; Lucca et al., 2019; Marchesini et al., 2022 Smeraglia et al., 2016, 2018). However, a few studies attempted to characterize the spatio‐temporal fluid paleo‐circulation along transects tens to hundreds of kilometers long (Callot et al., 2010; Crognier et al., 2018; Fitz‐Diaz et al., 2011; Kirschner & Kennedy, 2001; Knoop et al., 2002; Vandeginste et al., 2012), and rarely at scales covering entire fold‐and‐thrust belts (Beaudoin et al., 2014, 2022 for review; Cruset et al., 2023; Ghisetti et al., 2001; Smeraglia et al., 2022; Travé et al., 2007).…”

We combined field mapping, structural and microstructural analyses, stable‐clumped isotope geochemistry, and U‐Pb dating of calcite veins and syn‐tectonic slickenfibres, to assess the regional scale fault‐related fluid flow during the evolution of the External Hellenides fold‐and‐thrust belt. We show that fluid circulation during forebulge uplift was characterized by cold meteoric water‐derived fluids, from which calcite precipitated and sealed bed‐perpendicular joints likely formed during burial. Fluid circulation during foreland flexuring and early layer‐parallel shortening was characterized by warm fluids buffered by the carbonate host rock, which circulated through extensional faults and bed‐parallel veins. Mixing with meteoric‐derived fluids also occurred at this stage of tectonic evolution. Fluid circulation during the late stage of thrust wedge accretion and post‐orogenic extension at 1.6 ± 1 Ma was characterized by increasing dominance of cold meteoric water circulating in strike‐slip and normal faults. The ingress of external meteoric‐derived fluids was controlled by throughgoing fault conduits, while host rock‐buffered fluids were confined in isolated structures such as minor faults and veins. We developed a conceptual model of fault‐related fluid circulation, which invokes a transition from an open fluid system during forebulge uplift, to a semi‐closed fluid system during foreland flexuring and early layer‐parallel shortening, and to an open system during late thrust wedge accretion and post‐orogenic extension. This type of fluid circulation can have impact on fluid migration/leakage, including hydrocarbons, into or outside potential reservoirs in the highly prospective Hellenides‐Albanides fold‐and‐thrust belt, a renovated frontier for hydrocarbon exploration in the Mediterranean area.This article is protected by copyright.

“…Faults, which are commonly found in sedimentary basins, can serve as conduits, barriers, or combined barrier-conduit structures for fluid migration in the subsurface [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. The primary factors that influence their control based on fluid flow are their episodic seismic activity and sealing capacity during quiescence periods [18][19][20][21][22][23][24][25].…”

Faults play a pivotal role in controlling fluid migration and retention within sedimentary basins, particularly in the context of fault-bound hydrocarbon reservoirs. Assessing the stability and sealing capabilities of faults enhances our comprehension of these systems and aids in the identification of pathways for fluid migration. In this study, we focus on a series of fault-bound hydrocarbon accumulations located in the southern Wenchang A subbasin within the Pearl River Mouth Basin. We emphasize the significant influence of faults in governing the processes of hydrocarbon migration and accumulation. By leveraging 3D seismic data and well information, we have assessed the sealing potential of ten faults that either currently retain hydrocarbon columns or have the potential to do so. Our analysis reveals that even faults with a relatively low Shale Gouge Ratio (as low as 15%) can effectively support substantial column heights. Taking into account factors, such as the source rock maturity, fault activity, geometry, sealing potential, and the distribution of hydrocarbon accumulations, we have formulated a conceptual model for hydrocarbon migration and accumulation within the study area. This model underscores potential fluid traps within the rift basin, shedding light on the complex dynamics of hydrocarbon movement in this region.
