Discussion
Dr. P. E. KENT, after presenting Mr. Falcon's paper, commented on the wide possibilities for fundamental research that were offered by the Zagros Mountains. The gravity profile that had been exhibited was the only one that had so far been measured ; a series of roads crossing the mountains in other places would provide particularly easy opportunities for further work, which could be carried into the thrust zone of the main ranges with great advantage. Along these lines ample geological control existed and any survey work could be linked to the fundamental triangulation of the mountain belt. Farther south scattered gravity measurements on the Zindaan range had indicated an absence of gravity gradient, providing another problem for investigation.
The very long sections available at several points in the mountain range, individually exposing sequences from older Palaeozoic up to the Pliocene, without stratigraphical breaks of any major significance, provided outstanding opportunities for palaeomagnetic studies, for the geological column could be sampled and its magnetism measured at essentially single localities.
On the physiographical side the problems arising from the development of the fold-mountains and the rise of the "geoflexure" that had been described in the paper were susceptible of detailed study from the abundant evidence of terraces, old erosion-levels and similar features. The area had the almost unique advantage that all the products of erosion from early Tertiary times onwards were discharged into a barred basin (the Persian Gulf from the Straits of Oman inwards), so that their volume could
