Final sections after three steps of cross section construction across the central Kabir Kuh anticline . (A) Field and map data are used to constrain the shallow structure of the fold; (B) the Samand and Kabir Kuh exploration oil wells are projected into the section to construct the fold at intermediate depths; (C) the deeper part of the anticline is constructed assuming a constant shortening value through the complete section.
Three-dimensional view of the Kabir Kuh geological map (modified from MacLeod, 1970), showing the position of the cross section together with the location of field views of Figure 10. Fm. = Formation.

Helicopter view of the north-eastern flank of the Kabir Kuh anticline along its southeastern segment. The 200-km (124-mi)-long Kabir Kuh anticline forms the southwestern drainage divide of the Pusht-e Kuh arc constraining the Seymareh River valley that flows toward the Dezful embayment.

North-eastern back-limb of the Kabir Kuh anticline at the Gurpi-Pabdeh level showing a general dip of about 17º to the northeast and a short but 60º-steep domain separated by two nearly parallel axial surfaces defining the box folding shape.

Helicopter view of the Chenareh anticline surpassed by the Saidmarreh landslide in the lower right corner of the picture. The Saidmarreh landslide is the biggest prehistoric landslide, triggered by the collapse of 15-km long segment of the north-eastern flank of the Kabir Kuh anticline about 10,000 year ago. The landslide has a volume of about 20 cubic kilometers, a depth of 300 m, a travel distance of 14 km and a width of 5 km. This means that about 50 billion tons of rock moved in this single event!
