“…Ophiolitic rocks are fragments of oceanic crust and upper mantle which are widespread on the surface of continents along tectonic suture zones (e.g., Abbate et al, 1985;Boronina et al, 2005;Maury and Balaji, 2014;Segadelli et al, 2017b;Vacquand et al, 2018;Jeanpert et al, 2019). These rocks extend from the Alps to the Himalayas through, for instance, Cyprus, Syria and Oman, and are also present in various countries such as Cuba, USA, Papua-New Guinea, New Caledonia and Newfoundland (Abbate et al, 1985).…”

Ophiolitic formations play a critical role in the groundwater resource of numerous countries and areas. Previous studies show that the structural heterogeneities of these rocks, coming from the presence of both different lithological units and multi-scale discontinuities, result in complex hydrogeological features that are not well characterized yet. In particular, there is a need for understanding how these heterogeneities impact the hydrodynamic properties of ophiolitic aquifers and the highly variable chemical composition of the water. To this end, we conduct various kinds of pumping experiments between two boreholes 15 m apart in the ophiolitic formation of the Batin (BA1) site in the wadi Tayin massif of the Sultanate of Oman. Cross-borehole open pumping experiments, as well as multi-level pumping and monitoring hydraulic tests, are performed in conductive zones that were identified from temperature and flowmeter data, but also in low-permeability zones requiring

“…Island is a younger sequence of basement rocks that originated during the Oligocene to late Cretaceous geological ages (Maury and Balaji, 2014). The rocks are mostly granite and extensively weathered by tectonic processes that provide good potential for groundwater.…”

“…The electrical current is injected into the subsurface to measure the resistivity, providing depth of occurrence of groundwater and the thickness of the aquifer system, based on the contrast in resistivity values (Ali et al 2015;Devi et al 2001). The resistivity of natural water and sediment without clay layers varies in the range from 1 to over 1,000 Ohm.m depending on ionic concentrations and dissolved solids (Maury and Balaji 2014). Coker (2012) conducted successfully VES to delineate potential groundwater aquifers in Akobo area, Ibadan, South-Western Nigeria, revealing both weathered and fractured horizons of the productive water-bearing zones representing the groundwater potential aquifers.…”

Groundwater is the dominant source of water supply on Phuket island, Thailand. The water demand on Phuket has been increasing due to rapid urbanization and population growth. A scarcity of freshwater and over-extraction of groundwater may shortly become severe problems for Phuket. Geoelectrical data obtained by Vertical Electric Sounding (VES) were employed in this study to estimate the Dar Zarrouk parameters of the study area. Twenty-four VES stations were set up using Schlumberger configuration with a 1.0 m minimum spacing. The lithology layers from 24 unpublished borehole data indicating each subsurface layer were validated with the resistivity data obtained from VES. The geoelectric profiles gave a maximum of three layers with varying resistivities and thicknesses across each VES station. Two parameters (longitudinal conductance and transverse resistance) of the Dar Zarrouk model were calculated from VES data to generate the thematic maps in a GIS environment, thus the groundwater potential in Phuket Island was represented as a single map by using the weighted overlay technique in ArcGIS, based on both longitudinal conductance and transverse resistance. The groundwater potentials were classified into three potential levels (low, medium, and high). The results reveal that the highest groundwater potential areas are isolated and in specific locations, while the majority of area has medium level groundwater potential. Finally, the low potential zones are in the flank and the top parts of the study area.

“…It has been recognized that detachment faults often accompanying ocean core complexes at slow to ultraslow spreading Geochemistry, Geophysics, Geosystems 10.1002/2017GC007001 environments provide a pathway for hydrothermal fluids, hosting serpentinization processes (Escartin et al, 1997;Ildefonse et al, 2007;Kelley et al, 2005). To date, only a few terrestrial geophysical investigations have sought to characterize near-surface serpentinite processes and their relation to subsurface water-rock interactions (Abdalla et al, 2016;Dewandel et al, 2005;Maury & Balaji, 2013;Maury et al, 2016).…”

Geophysical remote sensing both on land and at sea has emerged as a powerful approach to characterize in situ water‐rock interaction processes in time and space. We conducted 2‐D Electrical Resistivity Tomography (ERT) surveys to investigate in situ hydrogeological architecture within the Jurassic age tectonic mélange portion of the Coast Range Ophiolite Microbial Observatory (CROMO) during wet and dry seasons, where water‐rock interactive processes are thought to facilitate a subsurface biosphere. Integrating survey tracks traversing two previously drilled wells, QV1,1 and CSW1,1 at the CROMO site with wireline and core data, and the Serpentine Valley site, we successfully documented changes in hydrogeologic properties in the CROMO formation, i.e., lateral and vertical distribution of conductive zones and their temporal behavior that are dependent upon seasonal hydrology. Based on the core‐log‐ERT integration, we propose a hydrogeological architectural model, in which the formation is composed of three distinct aquifer systems: perched serpentinite aquifer without seasonal dependency (shallow system), well‐cemented serpentine confining beds with seasonal dependency (intermediate system), serpentinite aquifer (deep system), and the ultramafic basement that acts as a quasi‐aquiclude (below the deep system). The stunning contrast between the seasonality in the surface water availability and groundwater storativity in the formation allowed us to locate zones where serpentinite weathering and possibly deeper serpentinization processes might have taken place. We based our findings primarily on lithological composition and the distribution of the conductive formation, our work highlights the link between serpentinite weathering processes and possible sources of water in time and space.
