Figure 2: Stratal slices through long-wavelength Euler-curvature attribute volumes with strikes of: (a) ±90 degrees, (b) -30 degrees, and (c) +30 degrees as indicated by the insets. In essence, Euler curvature is an azimuthally filtered version of the most-positive and most-negative principal curvatures, accentuating faults and flexures along any desired strike direction. The subtle lineaments seen in (c) may correspond to splay faults or relay ramps controlled by the major faults shown in (b).
