LOWER TRANSITION ROCKS. 151 



Here and there they are jaspideous ; but at other places the rock 



shows a decided tendency to become schistose. The haematite quart- 



zites are underlaid by micaceous argillites, greenish drab or greenish 



grey in colour. 



Two miles south-east of the southern end of the Sindigiri hills rises 



a hill of very slightly hsematitic quartzite which, 

 Other hematite beds. though 1qw (on}y about 1QQ feet hJgh aboye ^ 



plain), is remarkable for its bare and rocky character and very artificial 

 appearance, due to the peculiar nature of the jointing which affects it 

 and gives it from the east the appearance of a gigantic palisading. 

 The strike of the bed is northerly with a slight trend westward at each 

 extremity and the dip is easterly at angles of from 75 to 8o° east. 



Two miles further south and about three-quarters of a mile south- 

 east of the village of Dammur is a moderately large and rich bed of 

 haematite quartzite, which occupies a position in the band approximately 

 the same as the bed above named as far as can be seen ; but nothing 

 positive can be ascertained owing to the tremendous cotton soil spreads 

 which intervene and cover everything. These two outcrops appear 

 to occupy a much higher position in the series than that of the Sindi- 

 giri haematites which, like the Naddevi haematite, are low down near 

 the base of the series. 



The band widens considerably and is fully 6 miles across abreast 

 of Korlagundi, but then narrows again where it trends eastward. 

 Only trappoids and hornblendic schists with a little pale chloritic schist 

 are here exposed, the former to the south-west and the two latter at 

 and around the village of Korlagundi. 



Very little is to be seen of the Dharwar rocks in the section of the 

 band lying between Korlagundi and the Tungabhadra, near Chaganur : 

 the country is low and flat and greatly covered by cotton soil or shingle 

 beds of undetermined age. To the south and south-west of Chaganur 

 exposures of trappoid are fairly numerous, e.g., a green hornblendic 

 trappoid shown in the bed of the nullah north-west of Budihal. 



About half-way between Chaganur and Bellary lies a low, bare, 



Bevinhalli trappoid rocky hill of reddish brown and black colour, 



hllls * consisting of a dense hornblendic trappoid
