 diately north-east of Kampli ; also on a somewhat larger scale in the 

 banks of a nullah which falls into the Tungabhadra 43 miles north-east 

 of Kampli. These granite flows are best seen where the road from 

 Kampli to Itugi crosses the nullah. 



The village of Devasundra, 4 miles south-south-east of Kampli, 



stands upon an outlier of dark schists (hornblen-

die?), the area of which is quite uncertain owing 



to the extensive spread of cotton soil which surrounds the place and 

 hides everything effectually. This outlier is a link between the 

 Kampli patch and the northern end of the Copper Mountain ridge. 



To the north and north-east of Kampli the schists and trappoids 

 cross the Tungabhadra into the Raichur Doab, where they form, 

 roughly speaking, three triangular patches with their bases abutting 

 on the river. The north-eastern patch of these three abuts on the 

 continuation of the main band into the Doab and Hunugunda sec- 

 tions of it. Its southern part near the river shows a great develop- 

 ment of black trap strongly resembling parts of the Joga-Sultanpur 

 trapflows (see page 129). 



The beds seen in the banks and bed of the Tungabhadra, where the 



main band crosses it, are chiefly dark hornblendic

a fairly rich haematite quartzite band forms a low ridge which runs under 



the old keep which forms the western fortification of the village. The 



beds are distinctly seen to cross the river into a small detached hill on 



the Nizam's side of the river, but they there become poor in iron and 



speedily disappear in the general mass of schists. To the south they 



disappear under the cotton soil when the ridge they formed has died 



down to the general level of the country. The eastern side of the 



band is greatly obscured by cotton soil and the outcrops are very few 



and far between. At the great bend the Tungabhadra makes below
