90 MIDDLEMISS: THE GEOLOG? OF H)AB STATE, 



banding of the quartzite, striking N.E.— S.W., and at the dam 

 outflow. \ mile N.E. of Raighad, there are great ribs of vcrv 

 massive quartzite striking in the same direction and parallel to the 

 length of the dam. Nevertheless, there is considerable local con- 

 tortion visible in the outflow channel where occurs a perfectly 

 freshly cut section, 10 yards long. Another of these marked 

 ribs is found 1 mile N.W. of Raighad with the same direc- 

 tion of strike. Between Raighad and Bokhar all the hills are 

 composed of the same crystalline quartzite 1 as that at 2 miles 

 E.bvS. of Wantra. Very occasionally there is evidence of strike. 

 N.E.— S.W., with vague dip, locally high and varying, judging 

 bv certain more massive beds, and a rough banding. One band of 

 mica-schist to the south-east of Bokhar is 10 feet thick. All along 

 the hill foot from Raighad to Vagdi there are several prominent 

 ribs of stout, white, pinkish or clear quartzite, which descend by 

 side spurs to cross the line of the streams going to Phulpur and 

 Paliapur. Examining them in detail, one sees that there is no real 

 bedding in the sense of sedimentary planes of division. The whole 

 rock has been completely recrystallised and is merely platy in 

 certain directions. As to how far the extremely coarse colour 

 banding may represent a former stratification it is not possible 

 to say, but it seems quite possible that it does represent it. 



The almost level, plateau-like summit in the more connected 

 northern part of this hill-mass appsars 

 most likely to be due to a plane of denuda- 

 tion coincident with what elsewhere, and quite near, is overlaid 

 by -the nearly horizontal Ahmednagar Sandstone (see p. 138). 

 As has been noticed under the head of the Aravalli System, 

 the minute traces of Aravallis among the 

 Local traces of q Uar tzite fringe at Vagdi, Mahadevpura and 

 other places, as well as the well authenticated 

 presence of them in the wide plain some distance away from Raighad, 

 make it certain that the puzzling junction between the quartzite 

 and the Aravallis must be very nearly exposed in this locality, the 

 only impediment being the alluvium and the scattered debris of the 



quartzite. 



In addition to the expanded area of Delhi Quartzite and its 



south-western fringe just referred to, there 



Other semi-detached are a f ew more or i ess connected exposures of 



the same in a southerly direction that merit
