 sections is that the limestone is Infra-Trias. The matters about 

 which questions arise are — 



(1) whether the conglomerates or one of the conglomerates 



marked a belong to the basal bed of the Infra-Trias, or 

 to some other horizon, and 



(2) whether the schistose quartzites north and south of the 



area, called Tanols, are altogether older than the typical 

 Infra-Trias limestone of Sirban, or are altogether younger 

 than it, or are contemporaneous with part of it. 



The general lie of the beds gives one; very little of a clue in these 

 two sections, because the apparent dip is uniformly in one direction, 

 namely, N.N.W. at high angles. It may be noticed, however, that 

 in the section through Durri hill, 3,567 ft., the Infra-Trias limestone 

 is bent into a rather narrow but sharp synclinal, whilst underneath 

 the southern limb of the synclinal beds of purple quartzite, purple 

 shale and conglomerate appear, very much resembling the normal 

 section through the base of the Infra-Trias of Sobruh and Sirban. 

 Below the conglomerate again are purple quartzites generally schis- 

 tose and well-bedded. 



Before we can advance nearer to the truth concerning these 



questions, it will be necessary to pass on to 



tendin a g Tria f S rom nd near the next band of Infra-Trias as marked on the 



Bur°kot a m ° unLain to map, namely, the large area extending from near 



Doodha mountain to Burkot. Near Doodha 



some interesting facts may be noticed. Approached from the north 



by the village of Chunee Kot the much-weathered quartz-schists,
