78 FOOTE: GEOLOGY OF THE BELLARY DISTRICT. 



A system of faults will doubtless account for its anomalous position, 

 but they are not obvious on cursory inspection, and they will have to 

 be worked out by some future observer. 



No discrepancy appears to exist between the Kalhalli gudda and 

 Karabagaddi beds, and if their sequence is a true one they must 

 represent a series more than 12,000 feet in thickness. 



The rocks forming the north-western part of the Kunchur band, 

 and which are largely seen in the plains around 

 o a argi 1 es Hollal, consist almost entirely of grey and green- 



ish grey argillites, which on the surface are soft and of shaley consist- 

 ency and appearance. Whether they are much harder in depth I 

 cannot tell, for, being utterly useless for building stone of any kind, no 

 quarries exist in which unweathered parts are exposed to view, and 

 their relations to the other members are obscure ; but, as far as can be 

 seen, they form the uppermost division of the Dharwars in this region of 

 the rocks which are exposed to view. They roll about a great deal on 

 a small scale, but are very badly exposed. They give rise to an open 

 undulating country much covered with cotton soil and singularly bare 

 of trees through human agency. 



To the south of Kunchur in the southern part of the band we meet 

 first with a belt of schists and argillites, between 2 and 3 miles in 

 width, and, apparently, underlying the Kunchur haematite bed. A large 

 exposure of green and slate grey schists is to be seen to the north of 

 Nattur (4 miles south-east of Kunchur), where they dip north-west 

 from 50 to 6o°. 



South-east of this schist belt rise some hills about 300 feet high, 

 which are crested by two or three moderate sized haematite bands, 

 which have a southerly course for about four miles and then sink down 

 into the plain, the haematite bed disappearing at the same time. Here, 

 too, it was impossible to ascertain the positive relation of these beds 

 to those at and north of Kunchur. It is hard to imagine that they 

 really underlie the northern beds in true sequence
