Schematic illustration of the eigenvectors for two-dimensional (2-D) structures such as dykes and faults. a Basic model. In this figure, v 1 is the maximum eigenvectors of the gravity gradient tensor and points to the causative body. The angle α between the surface and the maximum eigenvector is the dip of the causative body. b Fault dip model. A basement consists of an assembly of high-density columns, and the angle, α, indicates the fault dip
