Zusammenfassung:The study area is primarily composed of volcanic rock and plain quaternary sediment. Extrusive and intrusive rocks are the two varieties of igneous rock that have been found. In the examined location, igneous intrusive rock, specifically biotite granite, makes up most of the rock formation. Grey to white colour, biotite granite has a phaneritic, coarse- grained texture. On the other hand, andesite, an igneous extrusive rock, makes up the minor rock formation. The study aims to identify the potential groundwater resources of the study area. Groundwater viability is examined using the Electrical Resistivity Imaging (ERI) method. Each of the survey lines extends over a length of 200 meters, incorporating 41 takeouts positioned at 5m spacing, and adopts the Schlumberger array electrode configuration. Both surface water and groundwater are essential resources in Kelantan for daily life; nevertheless, ongoing groundwater exploitation causes depletion. This potential is defined by low resistivity materials that can store large amounts of groundwater. As biotite granite is inherently unsuitable for groundwater collection between grains, possible fracture zones are highlighted as likely sites for groundwater presence. The 2D pseudosection results for all three survey lines emphasize a substantial accumulation of groundwater in a spatially expansive zone. This is because the resistivity value for all the survey lines is below 100 Ωm.
