limestone. The absence of the above formations, coupled with the 

 conglomeratic character of the base of the sandstcnes, and the inclu- 

 sion among it of an angular clastic breccia so plainly re-made from the 

 in situ brecciated cherty bands of the Infra-Trias, argue an uncon- 

 formity at this point. 



The rest of the way along the ridge up to Srikote, now fairly 

 horizontal though rugged, is composed of Nummulitic limestone. The 

 dip has slackened off from 40 to 6o° north-west and is now slightly 

 undulating only. 



Srikote point itself is just situated on the axis of a sharp anticlinal 

 curve in the Nummulitic limestone. Its northern slope is a dip plane 

 of 70 north-west in a good exposure, after which comes a fault and 

 the section repeats itself, beginning with the Infra-Trias limestone, of 

 which there is only a small amount exposed, then the sandstone with 

 the angular agglomerate at the base, and then Nummulitic limestone 

 again for nearly a mile, the ridge becoming very rugged and broken. 

 The strike gradually changes to east and west and the dip to the 

 north. Pale limestone is now interbedded with purple shales, and 

 then follow several hundred feet of purple shale, and then the latter 

 interbedded with Murree sandstone. The Murree sandstone then 

 increases in quantity, and it and the shales continue the rest of the 

 way to the top of Laichi Khun peak (8,8 11 feet). 



The outcrops of these beds to the west down the slopes and 

 likewise to the east were very well seen in their relative positions 

 from the ridge. 



The position of the Murree beds, capping as they do a great hill 

 such as Laichi Khun, and lying in such evident gentle superposition on 

 the top of the Nummulitic limestone as a great outlier, is a noticeable 

 feature here, for, as we shall see when we come to the description of 

 the Nummulitic zone and the north Tertiary zone, this clear and 

 straightforward superposition of the one on top of the other is but 

 seldom found towards the plain-ward edge of Hazara. 



The Infra-Trias and Nummulitic limestones described in the above 

 section are clubbed together both on Lydekker's map of Kashmir
