270 MIDDLEMISS: GEOLOGY OF HAZARA AND BLACK MOUNTAIN, 



this by the way. Throughout the whole of this western continuation 

 of the zone, even in its more northern and more disturbed sub-zone 

 north of Jhand and the Khairemurut range, the folding of the rocks, 

 their upheaval and relative denudation have been insufficient to expose 

 anything lower than the Nummulitic stage. 



As regards the continuation of my next zone, the Nummulitic 

 zone, in the same direction, we find that the line of its northern 

 boundary is hidden under Recent accumulations of the Hunoh 

 and Indus rivers until the Cherat hills are reached, when its normal 

 faulted boundary again appears. To the south of that line this 

 continuation of my Nummulitic zone shows, as in Hazara, the same 

 distribution of the formations from Trias to Kuldana beds with the 

 same noticeable absence of any recorded exposure of the slates which 

 presumably lie at some depth below the zone, but which the present 

 stage of the upheaval, disturbance, and denudation has yet failed to 

 bring to the light. As to any sharp division, faulted or only sudden, 

 between the Slate zone and the Crystalline and Metamorphic zone in 

 this direction information is wanting. 



On the whole, then, it is my belief that, regarding the continuation- 

 area west of Hazara, through the medium of Mr. Wynne's map 

 and sections, we may see every likelihood that it too preserves many 

 of those peculiarities of structure which I have defined as belonging 

 to and characterising my zonal divisions in Hazara. 



If reference be made to the comparatively recent paper by Mr. 



Griesbach on the geology of the Safed Koh, 1

structure similar to that of Hazara. At page 105, Mr. Griesbach consi- 

 ders the north skirting ranges of that mountain chain to be composed 

 of old metamorphic with palaeozoic rocks, much altered strata follow- 

 ing as a belt south of it, and with possibly some strata of older meso- 

 zoic age wedged as narrow strips into the belt of the latter. He 

 considers the main axis of the Safed Koh to belong probably to the 

 older palaeozoic group, whilst lastly, the southern skirting ranges
