In this study, we leverage seismic and gravity data from the Ganga Valley Basin, a significant sedimentary basin located in the Indian subcontinent adjacent to the Himalayas. Through a quantitative and qualitative interpretation of gravity and seismic data along the seismic line (AA'), we provide a comprehensive overview of the architecture and characteristics of the basin. Our analysis reveals that the residual gravity anomaly in the Ganga basin spans from -15 mGal to 24 mGal, indicative of the combined influence of thick sedimentary sequences in the basin. The residual anomaly profile identifies basement ridges, faults, and mega syncline structures in the seismic section (AA'). The gravity profile along the seismic section (AA’) unveils a gravity high of Precambrian sediments in the Gandak depression. These anomalies may stem from a dense, thick pile of sediment filling the basin.
