AbstractGravity and Magnetic methods are fundamental tools in mineral exploration, owing to their efficiency in detecting subsurface density and magnetic susceptibility variations commonly associated with mineralized bodies. In recent years, the integration of advanced data visualization techniques, particularly the use of heat maps, has significantly improved the interpretation of gravity and magnetic anomaly data. Heat maps provide a powerful means of visualizing spatial variations in geophysical parameters, enabling the clear identification of anomalous zones that may correspond to subsurface mineral deposits. These high-intensity zones often coincide with geological features such as fault lines and shear zones, which are known pathways for hydrothermal fluid migration and mineralization. Importantly, areas exhibiting steep geophysical gradients on heat maps frequently align with such structural controls, offering valuable insights into the tectonic setting and mineralization processes. This integrated geophysical approach not only enhances the targeting of mineral-rich zones but also reduces exploration risk, especially in geologically complex and poorly understood regions. The present study highlights three case studies from the part of South Rewa Basin, the Bastar Craton, and the Cuddapah Basin in India, where mineralized zones show a strong correlation with high-intensity regions on gravity and magnetic heat maps, affirming the effectiveness of this method in delineating prospective mineral targets.
