DESCRIPTION OF SECTIONS. 259 



ates of Saindak g.« s'-^h a coarse rock could only be of local develop- 

 ment. Or else the conformity of the Khirthar strata of Saindak with 

 respect to the underlying volcanic rocks may be apparent more than 

 real. Although there is no apparent uncomformity, yet it is just pos- 

 sible that a break does exist. I have mentioned the occurrence, at 

 various horizons, of conglomerates consisting of waterworn volcanic 

 pebbles which show that the products of eruptions had been piled up 

 to a sufficient height to form volcanic islands rising out of the sea in 

 which all these strata were being deposited. The volcanic conglomer- 

 ates of Saindak might represent such a local accumulation, and this 

 would account for the absence of some of the Ranikot strata. The 

 strata (k) might represent then the portion of the Ranikot missing at 

 Saindak. At Robit (page 85) the Ranikot strata do present a great 

 resemblance to these recks. A careful search for fossils in the strata 

 underlying the volcanic conglomerates of Saindak would probably 

 settle the question. 



If I had seen the junction of ihese rocks with the flysch strata 

 that border the Mirjawa plain (/), some definite indication might have 

 been found to discover their age ; but I did not reach that point when 

 examining the hills round the camp at Saindak, while the outcrop 

 could not be traced either from Mirjawa. The south-western extrem- 

 ity of the section (Fig. 17) shows the features observed in the 

 neighbourhood of Mirjawa. As the nature of the rocks and their 

 structure do not vary much in the direction of the strike, it probably 

 gives a fair idea of what would appear if the section had been com- 

 pleted along one line. With reference to the remarkable circum- 

 stance of the rocks dipping inwards along either margin of the range, 

 it will be noticed that the south-west dipping features extend much 

 further from the north-east margin than the north-east dipping struc- 

 tures do from the south-west margin. The structure is not absolutely 

 symmetrical: the movement in a north-east direction towards the 

 greater and deeper depression of the Gaud-i-Zirreh lake has been 

 greater than the south-westward movement towards the smaller and 

 less pronounced depression of the Mirjawa plain.
