Large-scale layering on the large lobe. a) Close-in view of the pitted terrain on the large lobe (Seth region). The red lines indicate some of the prominent lineaments, interpreted as surface expression of layering. b) A plane indicating the prevailing local orientation of the layers for the largest pit in the Seth region. c) A set of lineaments and high topographic reliefs on the opposite side of the large lobe. d) Same plane as in b) and two additional parallel planes. The orientation of these planes matches the lineaments and topographic reliefs, suggesting the latter are surface expressions of internal layering. We note that the local orientation of the plane may vary from place to place. For simplicity we assumed that the best fit plane does not change attitude within the large lobe. However, a similar conclusion applies for bending following the local convex shape, or along the y-axis in panel b).
