224 MIDDLEMISS: GEOLOGY OF HAZARA AND BLACK MOUNTAIN. 



Jhelum, the above boundary line, which now runs north and south, 



is simply marked by a succession of low gaps or depressions on the 



side spurs as they descend from the older zones to the west. This 



position is an exact reproduction of the similar line of division 



between the Nahan beds and the Himalayan rocks of Ganwhar and 



Kumaun. 



Sections in the Upper Tertiary zone. 



The lono- narrow band of Murree beds which travels south down 

 the right bank of Jhelum river shews very little 

 of interest until Dehvul is reached. The whole 

 way the sections, wherever visible, expose dips (whether normal or 

 inverted it is impossible to say) at moderate angles towards the 

 west. The sharpness of the boundary line between the Murree beds 

 and the older rocks is emphasized by the way different members of 

 the older zone come down against the fault, — in one place Infra-Trias 

 limestone, in another Trias, and further to the south Jurassic or 

 Nummulitic rocks. 



West of Dehvul in the Kaneir stream-bed the Murree beds are 

 separated from the older rocks of the Nummu- 

 litic zone by a narrow band of Kuldanas. The 

 following sketch-section, fig. 38, shews the 



arrangement: —
