I was therefore unable to examine what may bean important section. 

 In the distance the limestone resembled that of Khargin, and perhaps 

 the section here is analogous ; but it is on these slopes that one would 

 expect to discover the true relationship between the Doab series and the 

 fossiliferous beds of the Fusulina limestone. Below Doab-i-Mekhzarin, 

 the Doab series, with much volcanic material, extends along both sides 

 of the Surkkab to Barfak. To the north the long slope up to the 

 Cretaceous scarp is composed of the plant-bearing and Red Grit series 

 (Plates 5 and 15). A good section of the whole group of beds, from 

 Doab series to Cretaceous, is found in the small valley of Ishpushta 

 (fig. 9). Here dark needle shales, with some arenaceous layers, are

overlain by beds of grey volcanic ash. Over these is the Saighan 

 series, at the base of which there is a bed of soft white rock almost a 

 sandstone, but containing a considerable amount of volcanic material ; 

 it is probably an ash deposited in water. This is succeeded by the 

 characteristic shales, sandstones and conglomerates of the Saighan 

 series. 



Amongst the shales of the Doab series there are beds of amygda- 

 loidal trap and numerous dykes ; the latter extern I up into the basal
