LOWER TRANSITION ROCKS. 87 



South of Jajkal gudda the haematites lose their prominence, and 

 their place is taken by chloritic and other schists which have been 

 eroded down to a low level which continues to beyond the Chikka Hag- 

 gari river. South-east of the valley the ground rises again gradually 



B ds south of the an ^ f° rms several ridges of moderate size which 

 Chikka Haggari. run south-east into the Mysore territory. The 



eastern side of the most easterly of these ridges lies in the Bellary 

 district. The ridge consists of poor haematitic quartzite and coarse 

 schists, which are overlaid (?) by a great trap flow. This trap 

 apparently corresponds with the great flow which lies along the 



Trap east of Jajkal eastern base of the Jajkal gudda mass and ex- 

 g udda - tends north-west across the Kannevihalli pass 



and along the eastern base of the Mallapan gudda ridge. This flow 

 is lost sight of at, and to the south of, Chiggateri (Chiggatair) owing 

 to faulting which has brought up the gneissic rocks in its place, but it 

 reappears east of the Chikka Haggari and becomes conspicuous irr a 

 low hill south-west of Nagurkonda (Naugerconda). 



This trap flow is to the east of the Jajkal gudda mass and further 

 north-west, overlaid by a broad band of chloritic 



Maithur hill haematite. .... ... 



and hornblendic schists, which are in turn over- 

 laid by a rather big bed of haematite quartzite very poor in iron. This 

 forms the main mass of the Maithur (Mydoor) hill, which lies in the 



apex of the triangle formed by two faults inter- 

 Faults. 1 , & . . .. , 



secting each other at a point immediately north 



of Maithur village. 



An interesting outcrop of a true pebbly conglomerate with quartz- 

 Dagunahalli conglo- ltQ matrix is to be seen on a low hill just south 

 merate bed. of Daguna h a lli ( 2 miles south of Huvina Hada- 



galli). It is much hidden by red soil, but where exposed much 

 broken up into small pits like diamond diggers' pits, and near the 

 western end of the end among the pits I observed two small pjat- 

 forms neatly edged with lumps oi stone and strongly resembling 

 the sorting platforms used by the diamond diggers at Banagana- 

 palli. Despite of many inquiries through the taluq officials, I could
