The post-collisional Homrit Waggat ring pluton exposed in southeastern Egypt preserves a record of events in the magma plumbing system at mid-crustal depths (c. 11 km). The pluton consists of two successive granite rings: an inner syeno-granite ring (c. 630–626 Ma) and an outer alkali granite ring (c. 635 Ma). High-resolution aeromagnetic data for the total magnetic intensity were used to construct vertical cross-sections through the pluton to configure its subsurface geometry and internal structure. A reduction-to-pole filter was applied to the total magnetic intensity data to position the magnetic anomalies directly above their sources. Several derivation techniques were applied to the reduction-to-pole data, including the tilt derivation filter to highlight the subsurface structural contacts and faults, the analytical signal technique to delineate the concentric magnetic rings, and both 3D Euler deconvolution and 2D
