Figure 5: Simple 2D geophysical models illustrating the four main types of aeromagnetic signatures associated with intrasedimentary normal faults in the central Rio Grande rift. Model concepts can also be applied to other layered geology, such as volcanic flows. Profiles are computed for the reduced-to-pole magnetic anomaly (bold blue lines) and the horizontal gradient magnitude of the reduced-to-pole anomaly (HGM-RTP—solid gray lines). Magnetic susceptibilities are color coded and labeled.
