Tilt map [arctg (vertical derivative/horizontal derivative)] of the Magnetic anomalies reduced to the pole. The black 0 line indicates the structure boundaries when the structures are subvertical. The width of the − 45° to + 45° belt provides information on the depth of the roof under the flight level. The recalculated depths below the surface are indicated in white. The depths values in yellow were obtained on the reduction to the pole using the Vacquier method (1951)
