group slopes slightly to the northward, and in that direction the newer 

 members of the whole series prevail, until cut off by a fault from the 

 eastern end of the Chichali range. 



To the south, in the bank of the river Indus, just beneath the eastern 

 end of the town of Kalabagh, as well as to the 

 north of Uch-Tandar Khel, thick sandstones and 

 conglomerates are seen, the boulders in whish are large, and chiefly of the 

 ordinary metamorphic kinds, to be found in the bed of the Indus and in 

 the uppermost Siwalik beds. In the river bank they dip west-by-south 

 at 50°, striking directly at salt-marl on both sides of the river. In the 

 northern and much more extensive patch these beds are likewise highly 

 inclined, or curved and faulted against the adjacent rocks. In both 

 cases their occurrence is important, as fixing the date of the dislocation in 

 their vicinity within certain limits. 



The faults of the locality run in various directions ; they are too 



numerous to describe in detail, but one longer

than the rest runs up the Lun valley for ten miles, 



bringing the salt-marl and tertiary sandstones into contact at both ends 



of its course. 



East of the Lun nala the Dangot range and Bangali Sir mountains 

 are formed of a huge mass of the tertiary sandstones, 

 presenting bare rugged cliffs towards the valley, 

 but on the eastern side closely mammellated slopes formed of the con- 

 glomeratic upper Siwalik beds. These all bend round to the west-by- 

 south, joining with the rocks of the Lakargarh range, 14 miles north of 

 Kalabagh. The thickness of these sandstones and conglomerates is here 

 estimated at 9,500 to 10,000 feet.
