Advancing Geophysical Insights into Lithospheric Architecture and Tectonic Evolution
My expertise lies in applied geophysics, specializing in the use of gravity, magnetic, and geopotential data to explore lithospheric architecture and tectonic evolution. I focus on structural mapping and tectonic analysis of various geological environments, including continental margins, sedimentary basins, oceanic ridges, and shield regions. Developing and applying advanced gradient-based edge detection techniques is central to my work, significantly improving subsurface imaging accuracy. I also integrate potential field methods to study lithospheric thickness, thermal regimes, and deep crustal architecture, providing critical insights into tectonic processes and crustal dynamics across complex geological terrains.
Expanding beyond structural studies, my research includes geothermal reservoir exploration using gravity inversion and spectral analysis to estimate depths to heat-producing sources. I investigate seismic-induced mass redistribution, contributing to hazard assessments and renewable energy exploration. My multidisciplinary approach incorporates collaborations across geophysical disciplines, enabling integrated studies for groundwater potential and geodynamic interpretations. Overall, my work advances understanding of Earth’s subsurface processes, with valuable applications in resource exploration, tectonic reconstruction, and geodynamics.
Thesis Focus
My thesis on the Narmada-Tapti region addressed intricate tectonic events, magmatic intrusions, and plume activity obscured by Deccan volcanics. Through the development of the BHG edge detection filter and 3D density modeling, he identified pseudo-structural trends and critical crustal features, providing new insights into lithospheric thinning, plume-induced modifications, and seismicity.
