FOOTF. : GEOLOGY OF THE BELLARY DISTRICT. 



This trap and the schists No. 7 must be reckoned to belong to the 

 Kumaraswami division. 



The extreme south point attained by the Dharwar rocks lies a few 

 yards southeast of the 2,483 peak (Trigonometrical station) which 

 rises 1 J mile southward from the ghat road. Here a long narrow 

 strip of poor haematite quartzite, resting direct on the granite gneiss, 

 forms a miniature ridge a few feet high above the surrounding 

 crystalline rocks, which in the Trigonometrical station tower up some 

 sixty feet higher still. 



All the haematite quartzites remaining near the southern apex are 

 poorly ferruginous. 



The highly felspathic, rather pegmatoid, granites which are seen 

 cutting the schists No. 7 have in some cases a strong resemblance to 

 bedded or contemporaneous trap. Where weathered, they are often 

 hard to distinguish from the adjoining granite, where it is of a felspa- 

 thic character. 



C. — The Kumardswami, or South-Western Division. 



As above stated (page 90^ , the Kumaraswami division includes 

 the south-western half of the western side of the Sandur synclinal, 

 plus the Devadara set of haematites and schists forming the bold and 

 conspicuous ridge of that name, which has been left upstanding in the 

 centre of the southern half of the Sandur valley. 



The area measures twelve miles from north west to south-east, 

 and about seven across its greatest width along the south bank of 

 the Narihalla in the Ubalagandi gorge. To the south-east it tapers 

 to a mere point, thus forming a rather misshapen triangle, the 

 north-eastern side having an inward curve to the south, and the south- 

 western an outward curve to the south. 



As in all the other divisions of the synclinal, the haematite quart- 

 zites are the most conspicuous feature everywhere, though, if all the 

 surface were clearly exposed, they would in all probability be found 

 to occupy by no means the largest area,
