Oman, Wadi Bani Kharus. Angular unconformity Proterozoic-Permian. The lower sedimentary sequence is mostly rigidly rotated to make the Proterozoic horizontal. The unconformity is unfolded to be horizontal, but most of the relief on the unconformity is due to outcrop erosion. Photo Kees Rutten

Oman, Wadi Bani Kharus: major angular unconformity between Proterozoic and Permian

Notes: the strain overlay below shows that the reconstruction causes very little strain except for the blue strain patches associated with unfolding the unconformity itself.

Strain overlay, colour scale 10% dilatation (light blue), 20% dilatation (dark blue).
