Abstract

The Tatapani Geothermal Field (TGF), situated in Chhattisgarh, India, represents a significant geothermal prospect within the Son–Narmada– Tapti lineament zone. This study integrates geological and remote sensing analyses, along with subsurface data interpretation, to explore the geothermal potential of the area. Highresolution satellite data, including LANDSAT 8 and ALOS PALSAR, were used to generate Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) maps, which, when correlated with geological and structural features, revealed distinct geothermal anomalies. The presence of high heat flow values, magmatic intrusives, and neotectonic fault systems — particularly the Tatapani and Ramkola faults — were found to strongly influence geothermal manifestations. Structural lineaments derived from image analysis and slope mapping further validated the tectonic control on geothermal activity. The integrated approach highlights the role of deepseated faults, mafic intrusions, and crustal thinning in enhancing geothermal gradients, making Tatapani a promising candidate fo
