base of the series ; the lowest of them rests on red (haematitic) argil- 



Kalhalli gudda lites and S reen and ^^ SchistS * The CreSt ° f 



haematite beds. Kalhalli gudda, 1 the highest point in the band, 



is formed by two great haematite quartzite beds lying somewhat higher 



in the local series, and dipping westward at an angle of about 6o°. 



A little more than a mile north-north-west of the peak the beds make 



a short sudden bend from the north-west by north to north-east by 



north, and are cut off by a fault which makes them abut against the 



granitoid at foot of the ndge, which here terminates in a very abrupt 



slope. A lower ridge branches to the north -north-west and extends 



along the eastern boundary of the band, trending gradually to the 



north. Several considerable beds of haematite quartzite occur in this 



ridge and form parallel crests along it. 



Their southerly course trends westward from opposite the Kalhalli 



Karabagaddi hsema- P eak » and the y cross the Tungabhadra at Kara- 

 ite beds, bagaddi (Currabguddy) nearly 8 miles to the 

 south-west, and then immediately trend north-west and again west, 

 disappearing (dying out?) on the right bank of the Tungabhadra 

 at Hira Kuravatti. The haematites are thus seen to form in plan 

 a rude horse-shoe open to the north-west and having its apex at 

 Kunchur, where the lowest of the beds runs under the village, after 

 forming a bold rocky ridge which sweeps down from Kalhalli gudda. 

 The bed may be followed for some 3 or 4 miles south-west from 

 the village, but then dies away under a great cotton soil spread. As 

 seen in the low hills south-west of Kunchur, the rock is extensively 

 brecciated. As a glance at the map will show, the west side of the 

 horse-shoe is much the least developed. 



In the centre of the horse-shoe is another series of good-sized 

 haematite quartzite beds which form a shallow horse-shoe curve open 

 to the north. Their stratigraphical relation to the apparently under- 

 lying beds of the Karabagaddi beds is obscure. Still more obscure 

 is the relation of the great bed forming the ridge south of Yharada. 



1 Kalhalli gudda (Cullhully gooda) is the second highest peak in the western 

 taluqs, the highest being Mallapan gudda, 11 miles to the north-east, which attains the 

 height of 3,177 feet.
