tilted, stair-like appearance of the outcropping dip slopes, one 

 behind the other, through a vertical distance of 500 feet, is verv 

 marked south of Dhuleta. The marked schist bed, whose continua- 

 tion runs a little S.E. of Hunj is a muscovite-quartz-schist in which 

 the quartz grains are interpenetrated by sillimanite fibres, and in 

 which are garnets and ferruginous layers. This is very like Khond- 

 alite. All these facts seem to indicate an ascending series in the 

 Delhi Quartzite towards the Hathmati valley with its scattered 

 suggestions of the Phyllite Series.

towards Raighad, Navalpur and Mahadev- 

 pura in another, have only a very obscure relation whatever to the 

 representatives of the Aravallis that may be presumed to lie hidden 

 beneath the alluvial screen at their bases, judging from the few 

 exposures seen here and there. The only semblance of strati- 

 graphical order in the quartzites here is furnished near Raighad 

 and Vagdi, where a steady strike and apparent dips to the N.W. 

 at about 60°, might be construed as indicating a base or local 

 base of the quartzites near the foot of the scarp. For instance, 

 here at Raighad in the ridge above the town there is a marked
