KHIRTHAR RANGE. 83 



The section of the Gaj beds on the Mazarani Nai is poor, and pre- 

 Manchhar beds between sents no peculiarities. The dip is lower than 



Kenji and Burri streams. farther nQrtk The ^^ occupied hy t]ie Manchhar 

 beds is here wider than anywhere else along the flank of the Khirthar 

 range, and the country between the Kenji and Bu"rri streams perhaps 

 affords better sections of these beds than the ground farther south. 

 Still there is never a complete exposure of the strata as there is in the 

 case of the older tertiaries. The softer beds of the Manchhars are, as a 

 rule, very ill seen, and occupy large flats covered with gravel between low 

 ridges formed of the harder rocks. 



North of the Kenji Nai the Manchhar beds dip eastward for 

 Mancbhar beds on some distance from the base of the higher ranges ;

lower dip ; and they again turn over near the plains. The synclinal and 

 anticlinal roll becomes more marked on the Kenji Nai. Here, resting 

 upon the Gaj group, the lower Manchhar beds, consisting of more than 

 3,000 feet of grey sandstones, are followed by 1,500 to 2,000 feet of 

 orange clays (upper Manchhar), all dipping at 70° or 80° to the east. 

 Then comes a synclinal, to the east of which but few clays are seen ; 

 they may be cut out by a fault, but no other evidence of faulting was 

 noticed at this spot. The beds dip west for about 3 miles at angles of 

 from 5° to 15°. They then turn over again and dip eastward, and the 

 clays of the upper sub-division appear at the edge of the alluvium, dipping 

 east at about 40°. The section is, however, incomplete, the upper conglo- 

 merate not appearing, although it. comes in about 3 miles further south. 

 On the Mazarani Nai, the dips are lower, the outcrops consequently

river, the section west of the synclinal is completed by the appearance of 

 the conglomerate forming the uppermost of the Manchhar beds, so that 

 a perfect section of the Manchhars occurs between the outcrop of the Gaj 

 and the synclinal axis ; the latter being occupied by alluvium to the east 

 of the conglomerate ridge ; whilst further to the eastward the anticlinal
