B8 FOOTE : SOUTH MAHRATTA COUNTRY. 



Turning eastward thence,, no gneiss inliers are met with for a 

 distance of a hundred miles ; then at a Httle to the east of Jamkhandi a 

 narrow band of granite gneiss is traced between the foot of the 

 Jamhandi hills (Kaladgi conglomerates and quartzites)^ and the Deccan 

 trap occupying the valley of the Krishna. Ten miles to the south-east 

 there is another small inlier at Bisnal occupying a similar position. 



On the north or left bank of the Krishna, a few small inliers of 

 gneiss show between the trap and some small inliers of Kaladgi rocks 

 to the west of and at Mundapur. 



Three inliers of gneiss occur in the area of the Bhima series : one ten 

 miles east-north-east of Muddebihal (Moodebihal) ; a second at Salwargi, 

 ten miles east of Talikot; and a third of considerable size close to 

 Shahabad station on the Great Indian Peninsula Railway. 



The gneissic series includes a very considerable variety of rocks, 



schistose or granitoid, separated, as a rule, into great 



Arrangement in bands 

 ofgranitoid and schistose bands which may be traced in many cases for miles 



and miles across country. These bands are often 



very clearly, indeed sharply, defined, but yet it has been found very 



difficult to ascertain the relation subsisting between many of them. 



The rocks are often so much crumpled and distorted, or have been so 



greatly metamorphosed, that their bedding cannot be made out. 



Many of these bands of schistose or granitoid rocks can be traced 

 from the southern boundary of the younger azoic rocks or of the Deccan 

 trap, southward across the great plains of the Raichur Doab, and of 

 Dharwar districts to the banks of the Tungabhadra river, which they 

 cross, and stretch away into the as yet unexamined parts of the Bellary 

 districts and Northern Mysore. 



The prevalent strike of these great bands is north-west-by-north ; 



but this is not constant, and considerable areas are 



met with where other directions are followed by the 



lines of bedding. Thus in the eastern part of the gneiss area, the
