Abstract: This study offers a geophysical resistivity investigation of the Tiruvanmiyur region to look into structural features, groundwater potential, and subsurface lithology. Analysis of three MT profiles showed notable differences in resistivity values, which ranged from 17 Ωm to 122 Ωm and were suggestive of various geological formations. Moderate resistivity (22–53 Ωm) was found in Profile 1, indicating a shallow aquifer above a basement rock. The resistivity range (17–104 Ωm) was wider in Profile 2, suggesting a fragmented zone with possible groundwater movement that may have been impacted by faulting. A compact crystalline basement with low groundwater saturation was suggested by the mostly high resistivity (36–122 Ωm) seen in Profile 3. Due of Profile 2’s closeness to the coast, comparative investigation revealed a possible saline intrusion. The study emphasizes how groundwater distribution is impacted by structural discontinuities and lithological variations. The results offer vital information for structural geology, mineral exploration, and groundwater management in the coastal region of Tiruvanmiyur.
