Magnetics can be very valuable in interpreting [[seismic data]] by plotting residual magnetic profiles along seismic sections. This technique is valuable in looking for (1) subtle stratigraphic changes that can occur along [[basement]] block boundaries and (2) subtle fault offsets or other structural and stratigraphic features. The locations of the basement weakness zones provide focal points for examining the seismic data more closely. | Magnetics can be very valuable in interpreting [[seismic data]] by plotting residual magnetic profiles along seismic sections.
