458 Report on the Geological Structure of the Salt Range. [No.5 . 



presenting a succession of anticlinal and synclinal axes stretching 

 from N. E. to S. W. 



Table No. IV. 



Section across the Rhotas range at Mount Tillah between the 

 villages of Hoona and Bhet at right angles to the strike of the 

 strata. 



On ascending the hill from Hoon we have — 



1. A succession of Tertiary miocene strata containing numerous 

 mammalian bones, Saurian teeth, &c. Near Hoon they dip to the 

 S. S. E. at an angle of 70°, but on ascending the hill, they present an 

 anticlinal axis beyond which they dip to the N. N. W., as if under 

 the escarpment of Tillah, an appearance which is evidently produced 

 by a fault. 



2. Salt Marl with Gypsum. This is very indistinctly seen at the 

 base of the escarpment. 



3. Red Sandstone with bands of Conglomerate. 



4. Grey Dolomitic (Magnesian) Sandstone brecciated in some 

 places. 



5. Greenish micaceous Sandstones and Shales from the decom- 

 position of pyrites, apparently in some of the beds of shale ; they 

 have been converted into a red claystone. 



6. Red Clays and Schistose micaceous sandstones. 



7. Marly yellow nummulite limestone with Ostreae ; in some places 

 is a mass of these shells. 



8. Tertiary miocene strata similar to No. 1. 



Table No. V. 

 Section across the Salt Range near Baghanwallah. 

 In an ascending order we have — 



1. An extensive alluvial deposit of boulders of gravel, sand and 

 clay. 



2. Salt marl. This does not appear on the surface, but from the 

 abundance of saline efflorescence, evidently occurs beneath. 



3. Red sandstone with bands of conglomerate ; its lower beds are 

 schistose and argillaceous, contain laminae of gypsum, and are en- 

 crusted with a saline efflorescence. 



4. Greenish micaceous Sandstones and Shales. 



5. Grey Dolomitic (Magnesian) Sandstone.
