MAJOR EARTH-FLEXURING IN THE ZAGROS MOUNTAINS OF SOUTH-WEST IRAN

Abstract

Geological evidence is given for the existence of a major flexure, trending NW.–SE., the amplitude of which is 40,000 feet in the Bakhtiari and Kuhgalu Mountains. decreasing to the north-west and south-west. The date of the major flexuring is discussed and is it concluded that it is to some extent contemporary with the folding of the foothill belt. Gravity profiles are given which provide supporting evidence for the flexuring.
