sagar eastward from Gudur, also at Gajendragarh and in the valley to 

 the north-west of the town. 



The fact that where the sandstones are horizontal, or nearly so, they 

 are hut little altered, has already been mentioned, A very marked example 

 of their changing to quartzites where uptm'ned to a considerable degree 

 occurs a few miles westward from Gudur at Rangasamudra, a village not 

 shown in the Atlas Sheet (41) ; but wbich lies at the northern end of the 

 gorge by which the large Nilawagal nullah flows across the eastern end 



of the quartzite-sandstone area extending from 



Nilawagal nullah gorge, -r..,-. , n -\ir i ii i i-i 



Badami eastward across the Malprabha and which 



may conveniently be called the Wukund plateau. 



The eastern edge of this area is formed of sandstone beds lying 



slightly inclined to the south-west. Very soon,

however, the beds dip westward some 20° to 25 



towards a synclinal axis, while at the north end of the gorge they 

 dip south-south-west 65*^, and in both cases assume the character 

 of typical quartzites. At the north end of the gorge the change 

 may be traced all along with perfect ease, as the beds form a bare 

 scarp running south-eastward. The eastward continuation of the same 

 beds is seen capping the ratber high plateau south of Gudur in a per- 

 fectly horizontal position. The gorge of the Nilawagal nullah coincides 

 with the axis of the synclinal curve above named. The central part of 

 it is very picturesque from the recurrence of a great thickness of the cho- 

 colate-coloured breccia (" dirty breccia" in part) so frequently seen in the 

 north-eastern part of the Kaladgi basin, which bas been worn into higb 

 and rugged rocks and cliffs rising mainly on the left (western) bank 

 of the nullah. Westward of this nullah the beds resume their relative 

 horizontality, or roll about at very low angles, and again present the 

 simple hard sandstone character. 



North of the Gudur nullah is another extensive plateau of sandstones, 



partly horizontal, partly rolling about at low angles.
