BAKRALA RIDGE. 121 



limestone makes its appearance amongst local dislocations^ and may be 



traced at intervals as far as the hill over Dom(^li. The ridge here 



becomes double and much wider, a long valley and other depressions 



dividing it midway longitudinally. The lime-

stone occurs on the top of the southern elevations, 

 being apparently brought up by a greatly compressed and broken anti- 

 clinal fold. It contains numerous casts of Gastropoda and some 

 Nmjimulites. In a clunchy shale below are large and small Ostrece, and 

 the lowest beds seen are of hard red ferruginous and spotted amygdal- 

 oidal-looking hsematitic clay of lateritic aspect :* (See fig. 7 (Plate X), in 

 which a is nummulitic limestone ; b, Nahan ; e, Lower Siwalik ; d, Upper

The chief fracture which has brought these limestones, &c., into 



view is not very easily traceable among a number

of smaller disturbances, but seems to have had an 



east and westerly direction, north of Domeli ; and the limestones, &c., 



do not continue in this direction across the river, on the banks of which 



that village is situated. 



The anticlinal arch has here lost a good deal of its symmetry and 

 Unsymmetrical anti- become normal, the angles to the north being low,

beds vertical, or closely crushed. A soft red zone also occurs at the outer 

 foot of the hills on the Domeli side, and appears to occupy most 

 of the escarpment of Nili hill near the centre of the ridge : ( fig. 8,

The tertiary sandstones and other beds of this part of the range are 



frequently covered by a white saline efilorescence ;
