THE KANI QADIR FOLD. 57 



recognizable anticlinal structure remains, most of the south-western 

 limb having been cut out by a large reversed fault along which the 

 north-eastern limb and perhaps a small portion of the crest have 

 been thrust up over more than a mile of strata. A narrow outcrop 

 of Fars beds, striking N.W. — S.E. is thus brought into contact with 

 the Upper or Conglomeratic stage of the Kurd series.

Fars series. — The Fars beds consist of a central core of limestone 

 which, assuming the fault to be a fold-fault, probably represents a 

 more or less fractured anticlinal crest. This core on the south-west 

 is bounded by the reversed fault ; on the north-east it is succeeded 

 by a band of clay and sometimes a little gypsum, and then usually 

 •by another thin limestone band. Above this come the red clays 

 and sandstones of the Kurd series. 



Kurd series. — In the Kurd series the three zones of the Lower 

 stage, described in the last report, can be dimly recognized at the 

 northern end of the area. Here a soft belt of cultivated ground 

 slopes down from the Fars outcrop to a north-westerly-flowing 

 stream, and consists mostly of clay whose superficial colour is more 

 brown than red owing to the silt spilt over it from the Conglomeratic 

 stage of the Jabal Nasaz ; this constitutes zone " a." North-east 

 of the stream sandstones become a little more frequent, and produce 

 gradually rising ground as far as a low watershed, but there is still 

 much red clay present. Beyond the watershed brown clays of 

 zone " c " become thicker and thicker until they practically mono- 

 polise the succession ; these brown clays are seen stretching for a 

 long distance north-eastwards. The more sandy phase separating 

 the clays of "a" and "c" represents zone "b." In the southern 

 portion of the area there is the same belt of cultivation, a similar 

 longitudinal stream — south-easterly in this case — and rising ground 

 beyond, but sandstone ridges, though short and inconstant, are 

 locally as plentiful in zone " a " as in zone " b," such as those pro- 

 ducing the hills immediately north-west of Kani Qadir ; no definite 

 line can be drawn between zones " b " and " c," the clay of the 

 latter being redder than usual. In all three zones clay greatly 

 predominates, and there is not so much of that regular system of 

 parallel ridges and valleys so typical of zone "b"; the clay has thin 

 sandy partings which indicate the dip very precisely. South-west
