98 MIDDLEMISS: GEOLOGY OF HAZARA AND BLACK MOUNTAIN. 



regularity of dip in one of two directions, but in amount and absolute 

 direction the evidence offered by the imperfect sections exposed is 

 not conclusive. The general impression that one gets in studying 

 the section is that there is considerable folding and contortion of the 

 strata, a view that is borne out by the repetition of the limestone 

 bands of the nature of the Lunguryal band, one of which is seen at 

 Bandee Sher Khan, and others along several lines between that village 

 and the watershed. The band at Busera resembles the one found at 

 Phoolan Gulee in an uncertain way, both being slightly metamorph- 

 osed with a faint marble-like aspect. The rest of the bands all 

 resemble the Lunguryal band which has been described in the chapter 

 devoted to the petrology of the stratigraphical elements. 



Besides the evidence of repetition of these bands, the dips are high 

 wherever actual sections are well exposed, as, for instance, along the 

 road near Phoolah Gulee. North of this place there is a massive dip 

 of some quartzose varieties of the Slate series (which is probably 

 a real dip) in a north-westerly direction. 



It will be seen that two of the limestone bands referred to above 

 die out about the position of Maira Turla. This dying out seems to 

 be by loss of material — a gradual process of thinning out, though it 

 might have been partially effected by the continuation in that direc- 

 tion of the Naruh fault (see Nummulitic zone). North-east of Maira 

 Turla there are no more instances of limestone bands interbedded 

 with the slates ; but to the north-west, in the Gundgurh range, as we 

 shall see, they attain very great individual thicknesses. 



Sir ban hill sections. 

 Leaving the simple aspects of the Slate zone, as evidenced near 

 Hureepoor, we will now examine the Sirban hill. On account of its 

 classical associations in the history of geological investigations in 

 this part of the Panjab, I propose to treat it more fully than I should 

 otherwise do. Moreover, in consequence of its epitomising much of 

 the geology of Hazara we shall gain something by examining it 

 minutely as a type of much that will follow. Dr. Waagan and Mr- 

 Wynne have described this hill in considerable detail in their joint
