(a) Morphotectonics of sites 3a and 3b along the southern part of the northern segment of the Kazerun fault on a 15-m resolution ASTER image (See Fig. 2 for location) (coordinate system is in WGS 1984 UTM zone 39N). Fault traces are in black. The studied fan-terraces are in white. Differential GPS survey route is shown in black dotted line. Dots and letters refer to ³⁶Cl samples (Table 1). (b) West looking view of the anticline developed above the southern fault at site 3a. (c) Differential GPS topographic profile of the fan-terrace surface showing fault scarps at site 3a (located on Fig. 7a).
