122 WYNNE: TRANS-INDUS SALT REGION, KOHAT DISTRICT. 



side, but seen to take the ground nosing to the eastward and consecu- 

 tively enfolded by the sandstone and clay series, where the Kohat and 

 Bannu old road has been abandoned for a better line curving round the 

 end of the range close to the south bank of the Teeree (Tiri) Taui 

 river. 



The whole of this range from Manzulli to Banda, apparently in 

 Complex character of consequence of the large development of gypsum 

 and soft rocks within the limestone-crested ridges, 

 and the great pressure exerted upon them, presents some of the most 

 complex ground in the district. From the details given, it will be seen 

 that in many places it is difficult to conceive what forms eroded 

 or denuded portions of the sections may have taken. It will be also 

 evident that without the existence of the few sections in which the 

 rocks are normally superposed south of Teeree (Tiri), and the evidence 

 afforded by the anticlinal south of Banda, or similar sections elsewhere, 

 the task of reducing such a mass of contradictory confusion to anything 

 like proper order would be well nigh hopeless.

is little less complicated than the more extended range just described. 



The rocks are broken and displaced by faults, yet remnants of a 

 former ellipsoid structure are to be recognised in the narrow and frag- 

 mentary bauds of the nummulitic limestone along its southern or scarped 

 side.
