366 Report on the Geological Structure of the Salt Range. [No. 4. 



strike elevating the northern portion into a high ridge, the strata 

 forming which have a northerly dip, and present a steep escarpment 

 to the south. Along the south side of this line of fault the mio- 

 cene strata seem only to have suffered, and are either thrown under 

 the older elevated strata of the escarpment, as along the south side 

 of mount Tillah, or tilted up at a high angle with a southerly dip, 

 as at Jelalpoor. Moving westward, the elevatory action seems to 

 have extended laterally over a greater surface, and to have produced 

 several lines of fault which, in the central part of the Salt Range, 

 have in some places thrown the strata into great confusion, and 

 caused the formation of numerous longitudinal valleys, ridges and 

 transverse ravines. In section No. 8 two very distinct faults, seen 

 in the range west of mount Sikesur, are represented. 



At Moosakhail where the range running in a north-west direction 

 is not more than three miles broad, and is intersected by a trans- 

 verse gorge, an excellent section is exhibited of the strata from the 

 carboniferous limestone to the miocene beds. Here the upheaving 

 force has raised the carboniferous strata into an anticlinal ridge, 

 and without fracturing them has produced a graceful curving which 

 is well seen near the entrance to the ravine. Above the carbonifer- 

 ous strata, a fracture has extended through the oolitic and superin- 

 cumbent rocks, dipping to the IS. N. E., and a vast amount of their 

 debris covers the carboniferous limestone as it dips to the S. S. W. 

 under the plain. Between Moosakhail and the Indus, where the 

 range again expands, and is eight or nine miles in breadth, considera- 

 ble disturbance prevails among the strata. 



When describing the position of the Kalibagh coal we alluded to 

 the overturning of the strata in the Kalibagh hill, and need not 

 refer to it again. 



In the Chichalee Eange which runs from north-east to south-west 

 the elevatory action seems to have extended laterally with violence 

 over but a small extent, but has produced a most remarkable and 

 distinct overturning of the strata along its south-east or scarped 

 side. This is represented in section 9 as seen in the Chichalee pass, 

 at the entrance to which, in an overturned position, the strata from 

 the miocene sandstones, &c. to the oolitics, may be observed, and 

 separated by a fault from the same beds on a steep escarpment, 

 in regular order, dipping to the north at an angle of from 30° to 35°.
