“…In contrast, the waters from the Cueva del Agua spring (8) and the Belerda spring (10) are subsaturated in these clay minerals; therefore, the dissolution of these minerals might be possible. The samples from the Higueral spring (2), Church Huesa spring (3), Carboneras spring (5), and Candilejo spring (7) are close to equilibrium in relation to clays. PHREEQC did not calculate the SI for the samples from the Rosales spring (1), Vadillo 3 Caños spring (6) and Don Pedro spring (9) due to the very low content of Si and Al, which could suggest no precipitation and dissolution for these minerals.…”

“…Fault zones have the capacity to be hydraulic conduits connecting shallow and deep geological environments [1][2][3]. Mineral precipitations along fault zones are usually considered an indication of accentuated groundwater flow through faults, e.g., [4][5][6]. The crystallization of mineral phases in fault areas is controlled by the chemistry of circulating fluid, the characteristics of the fault rocks, and the physical factors present at the time of mineralization.…”

A hydrochemical and mineral study of groundwaters and damaged rocks from the Tíscar and Larva fault zones (Betic Cordillera, Iberian Peninsula) was carried out in order to (a) describe the physical and chemical properties of the groundwaters; (b) recognize significant locations with deep-origin fluids related to active tectonics; (c) and to describe the water–rock interaction and the neoformation of clay mineral processes and their importance in the seismicity of the faults. A sampling campaign was completed between November 2012 and November 2013, during which data were obtained from 23 different groundwater sites in the fault areas. Two main groups of waters were distinguished: (a) Ca2+-Mg2+-HCO3− facies characterized by poor conductivity and salinity; and (b) saline waters (up to 30 meq/L) rich in Ca2+-Mg2+-SO4-Cl− and with an elevated conductivity (frequently > 1000 μS/cm). In addition, a minor group of saline and warm waters (T > 16.5 °C) was found to be Na+-rich and show moderately high B values (>0.33 ppm), and which mig ht be hosted in aquifers deeper than the two main groups. This group of deep-origin waters is oversaturated in clay minerals and is in equilibrium for Ca-Mg carbonate minerals. X-ray diffraction and scanning and transmission electron microscopy data corroborate the crystallization forecast of authigenic smectite, which appears as thin films coating carbonate fragments. The origin of smectite is related to the fragile strain and thermal–fluid–mineral interactions in fault rocks. Smectite could lubricate carbonate rocks, which favor creep deformation versus seismic slip. This work provides locations where groundwater physico-chemical properties and composition suggest tectonic fault activity.

“…For example, the new lakes in the Taklamakan Desert and the abundant groundwater and lakes in the Badain Jaran Desert have been reported to be related to faults (Chen et al, 2012;Jin et al, 2018). Faults also distribute fresh groundwater in central Iran (Chitsazan & Manshadi, 2021). River water with depleted stable isotopes and high concentrations of major ions, such as 222 Rn, indicate that faults influence the flow paths of the groundwater discharged to the river (Tan et al, 2020).…”

In arid and semi‐arid areas, local precipitation is insufficient to fulfil the water requirements of the fragile local environment; hence, water is obtained from groundwater. The Hulun Lake Basin is located in the Mongolian Plateau, which is home to numerous lakes. In this study, we used remote sensing and isotopic tracing of naturally occurring isotopes (δ18O, δ2H, and 87Sr/86Sr) to identify and quantify the various water inputs into the basin. Based on the lake water balance calculation and precipitation and river inputs, a 5.4 × 108 m3/year groundwater recharge rate was determined. Groundwater and river water with depleted δ18O and δ2H were identified close to the faults near Hulun Lake. The groundwater recharge into Hulun Lake is aided by the faults. The δ18O and δ2H compositions of the groundwater, rivers, and lakes were consistent and more depleted than those of precipitation in the local mountains and plains. Therefore, the rivers and lakes are assumed to be primarily recharged by groundwater. The low strontium isotopes (87Sr/86Sr) in the samples suggest that the water was primarily recharged by basalt groundwater, which was identified under the Cenozoic strata instead of the sandstones, granites, and tuffs, which are the primary rocks in the study area. Moreover, the faults were widely distributed in the study area, allowing for groundwater upwelling from basalts. For the areas with volcanic rocks and faults, particularly in arid and semi‐arid areas, the basalt groundwater recharge through faults is critical for environmental sustainability. This research provides necessary information for future hydro‐ecosystem resource management in arid and semi‐arid areas.

“…Spatial/ temporal analysis of the karst subsurface river shows that hydrochemistry of karst water, especially in total dissolved solids (TDS) and pH, was affected by precipitation during the flow process [10]. On the other hand, the quality and origin of groundwater, including the transport mechanism, can support the conservation of existing water resources, such as springs, wells, and river water [11], and protect fresh groundwater [12]. The hydrochemistry in karst doline water has not been studied specifically, so this paper aims to complement the karst research, especially Gunungsewu.…”

The Panggang and the Wonosari-Baron Hydrogeological Subsystems are part of the Gunungsewu karst landscape in Gunungkidul Regency, Yogyakarta, Indonesia. This landscape has many dolines as one of the epikarst of the phenomenon. These dolines usually classified as solution dolines. This study aims to determine the presence or absence of groundwater flow in doline based on hydrochemical characteristics. Hydrochemical data were collected during the dry and rainy seasons, supplemented by water doline sampling on the ten selected dolines. Data were taken from the field and laboratory, both in physical (color, taste, odor, and turbidity) and chemical (pH, EC, and ionic content) properties of water. The hydrochemical analysis was performed using Stiff and Gibbs diagrams. The doline's water has Ca and Na-bicarbonate facies during the dry season but tends to change to Ca-bicarbonate facies in the rainy season. The water-rock interaction process and precipitation found strongly influence the hydrochemistry of dolines water. The hydrogeological system involves conduit-type groundwater flow. The groundwater is interpreted to contribute to the water doline based on its hydrochemistry, both locally and regionally.
