78 BLANFOUD : GEOLOGY OF WESTERN SIND. 



several on the plateau, some of them being broad fissures partly filled 

 up by earth below, and with " swallow holes " down which water evi- 

 dently runs, in the bottom. The accumulation of soil on this and 

 similar plateaus is probably due to the want of an outlet. 



In the lower ranges east of the main ridge the geology is rather 

 Junction of Manchhar more confused than it is further south, owing to 

 Lalan stream. disturbance and some faulting. On the Lalan 



stream, about 4 miles north of the Kenji, the Manchhars are distinctly 

 seen to be faulted against the Khirthars. That the junction is a fault 

 is shown by the rocks being completely smashed, and by fragments of 

 Nari sandstone being mixed up with them. 



There can be but little doubt that this fault is a continuation of 

 r Remarkable faults that seen west of Kitchi and again on the slope 

 Piro & range. of Miagwan. On the continuation of the same 



line a fault is seen crossing the Kenji Nai at Lakha-jo-Kandi, and 

 may be traced to the southward along the western side of the Piro 

 range, a lower ridge near the base of the main Khirthar chain, to beyond 

 Karch, or for more than 20 miles from the Kenji Nai, whilst the 

 extension to the northward, if the fault, as appears probable, is con- 

 tinuous throughout, would add 25 miles more. It is true that the fault 

 was only followed south of the Kenji Nai ; to the northward the ground 

 is so rough that more time than could be spared would have been 

 required to trace the line of dislocation ; but so far as could be made 

 out, the northern extension of the fault is on the same line as the 

 southern. The most remarkable fact about this fault is that the throw 

 at the Kenji Nai and to the southward is to the west, whilst to the 

 north the throw is in the opposite direction, or east. It is certain 

 that the amount of the throw varies greatly ; at Lakha-jo-Kundi, on 

 the Kenji Nai, it does not, in all probability, exceed 300 or 400 feet, 

 whilst at Bedo, about 8 miles further to the south -south-west, the 

 throw appears to be about 2,500 feet. South of this, along the Piro 

 range, the amount again diminishes, but throughout the Karch valley, 

 Khirthar rocks are brought against Nari beds. Towards the head of
