Analysis of Aeromagnetic Data Over Part of Bundelkhand Granite Complex for Geology and Structure

摘要

The interpretation of aeromagnetic data over Bundelkhand Granite Complex (BGC) in parts of Lalitpur District (U.P.), Sagar and Chhatarpur Districts (M.P.) has revealed the structural patterns such as the boundaries of various geological formations, magnetic body axes, depth extents of intrusives and thickness of various litho-units which may be of help in mineral exploration. The aeromagnetic features were found to correspond well with various geological formations like Bijawars, Vindhyans, Deccan Traps and BGC. The average depths of magnetic interfaces were estimated to be at 7.1 km, 1.9 km and 0.47 km from the observation plane (625 m above m.s.l.). The thickness of Deccan Traps was estimated to be of the order of 0.47 km from the plane of observation.
