SHEKH BUDfN HILLS. 79 



most probable case I observed of an inferior position for these beds 

 occurs in the Hasham tanga, on its north side, south-west of the 

 station ; even here it was not certain that slipping of a portion of the 

 higher rocks had not taken place. 



Nearly always in contact with this black zone on external parts of the 

 Sandstones above ju- hill are to be found tne whitish or light -coloured 

 rassic beds. sands and sandstones of the, perhaps, partly creta- 



ceous and partly post-eocene or even upper eocene band which intervenes 

 between the Jurassic and tertiary formations; they sometimes appear 

 either not to have been deposited or else to have been squeezed out of 

 place in the sections, and they vary somewhat, both in thickness and 

 character. Not unfrequently sharp checks, faults and omissions of the 

 group, are to be found, probably resulting from the intense crushing at 

 the contact of rock masses having so great a difference in hardness as 

 the Jurassic limestones possess compared with the Siwalik rocks. 



Succeeding the sandstone band (No. 8) of this section comes the enor- 

 mous mass of the Siwalik sandstones of the Nila 



Siwalik beds. 



Roh and Bhatani ranges, almost entirely without 



the frequent alternations of clays to be found in other districts, until the 



uppermost part of the group is reached! Here a comparatively narrow 



band of the usual drab clays seen at the top of the upper Siwalik beds in 



the Indus section closes the series as exposed. A section over Shekh 



Budin is given in figure 10 at page 78. 



This being one of the most, if not the most, interesting portion of the 

 trans-Indus extension of the Salt Range, as well as the farthest point 

 in this direction at which the relations of the palaeozoic, mesozoic, and 

 tertiary rocks are known, I append a coloured reduction from the recently 

 completed frontier survey of the locality, on the scale of one inch to a 

 mile, four times as large as that of the map to accompany this paper. 



The tertiary sandstones in the neighbourhood of the spurs nearest to 



Faulted tertiary junc- the Pani&la staging bungalow are seen to be in 



several places faulted against the Jurassic rocks, and 



on the south-western side of the Khavuri tanga, near its mouth, there is
