Normal & Reverse Polarity in Seismic



When a minimum phase wavelet  in normal polarity ('a' in picture) strikes a contrast impedance medium then it could be marked in near trough for increasing impedance medium in earth.

When a zero phase wavelet in normal polarity ('b' in picture) strikes a contrast impedance medium then it could be marked in centre of trough for increasing impedance medium in earth.
