MAIDAN RANGE. 01 



Section III. — The Maidan Range. 



This is but a different name applied to the double chain of the 

 Chichali and Shingarh ranges after it has curved to the south ; indeed 

 the Shingarh chain has no separate existence east of the Chichali 

 pass, and is closely united with the Maidan range to the south. 



At Mulla Keyl the narrow longitudinal Baroch valley, lying between 

 Baroch valley. Mulla * ne two ranges and bending with them and the 

 Kev1 ' strike of the rocks, discharges the drainage from 



both its northern and southern branches upon the Ismail Keyl plain, 

 cutting a crooked but fine gorge, called the Harma Kas, across the very 

 heart of the outer ridge. 



The fine section in this stream and the adjacent cliffs exposes a great 

 anticlinal curve, sinking to the south, and coinciding with the axis 

 of the outer range. In the centre of the arch nothing is exposed below 

 variegated Jurassic beds, and not the whole of these. Overlying them are 

 the upper calcareous part of the group, the supra- Jurassic sandstone, and 

 the nummulitic limestone, which forms all the highest ground. 



Ascending the stream the first rocks seen, forming a low spur behind 

 the village, are greatly crushed, faulted, and displaced masses of upper 

 tertiary sandstone, upper eocene sandstone and conglomerate, white 

 nummulitic limestone, and the underlying thick, pale, sandstone, belong- 

 ing before dislocation to the outer limb of the anticlinal. 



Next seen are some 400 feet of the upper Jurassic limestones, the 

 lower part shaly and with but few fossils, amongst which are some Corbulce, 

 Rhynchonnellce, Natica, and whole beds formed of small thick bivalve 

 shells impacted in the rock. Among these limestones are a few sandy 

 bands ; some beds are lumpy, some pebbly with limestone pebbles, and 

 others show small branching f ucoids ; most of the beds are fine and 

 earthy like lithographic limestone. These beds form all the cliffs south 

 of the stream. To the west they seem thicker than 400 feet, and from 

 beneath them rises the bulk of the variegated group towards the north. 



In the centre of the arch the variegated beds are composed of gray
