DELHI QUARTZITE SERIES.

just described, we find the hill masses further reduced in height 

 and characterised by still more intrusive masses of quartz-porphyry 

 and possibly granite. Here J first examined the two little isolated 

 knolls of Delhi Quartzite surrounded by alluvium 1 .1 miles due south of 

 Jamla town. Their outlines are of no particular shape as indicating any 

 structure. The rock is pale, slight lv reddish in colour, of fine grain 

 and not very massive. There is a fail amount of vein quartz among 

 the quartzite. The main mass of the Jamla hills N.N.E. of the 

 town, the 757 feet hill and its continuation through the town, and 

 also the ridge next to the east of that, are composed of hard and 

 glassy quartzite with obscure bedding. Neither in the shape of 

 the hills, nor from evidence of any scarps or dip-slopes, could I 

 see any sign of bedding and also no coarser or finer bands. It 

 seems that all stratification has been masked by subsequent pressure- 

 cleavage or rock-flow or something similar. The hill-side | mile to the 

 north of Jamla shows a similar absence of bedding. At the crest 

 of the same spur a pale blue-grey quartzite is entremely hard and 

 harsh causing very rough walking. The spur is rounded and hog- 

 backed with just a faint suggestion of dipping away from the 

 porphyry. This is especially most noticeable at the south-western 

 end of the 846 feet spur about 2 miles E.N.E. of Jamla, the strike 

 being N.E.— S.W. Jn sections 1 mile S. E. of Jamla the rock is the 

 same as in the other places described, with uncertainty of dip.

ing in height down to the alluvium. It is of 

 rather coarser grain than at the south-western end of this hill-mass. 

 There is no good bedding except locally. One can see that there 

 is some sort of folding of the hill-mass, but as there is no interbedding 

 of coarse and fine, or of any other thin-bedded rock, one cannot 

 solve the kind and amount of the folding. We may perhaps deduce 

 a general N.E.— S.W. strike from the run of the range and a con- 

 siderable amount of folding. The highest points of these hills 

 marked 961 and 969 feet respectively are about 450 feet above tire 

 general level of the surrounding plain. 



The detached, winding, very low, flat, ridge of quartzite at Kesar- 



Kesarpur. l mr ' uctween Kaniol and Khanusa revealed 



nothing except its abrupt junction with the 

 granite south of Kesarpur, which argues intrusion.
