east, the conglomerates and sandstones appear to he 



almost entirely undisturbed, and to be occupying' their original positions 



of deposition, and in them a minimum of metamorphic action is found 



to have taken place. Nearly the same may be said of the greater mass 



of the beds in the western part of the basin and in the outlying areas 



occurring in the different valleys on the gh^ts. 



In the conglomerates and lower-lying grits the color of the rock 



varies much more than in the higher-lying beds, and

indeed, often changes rapidly within short distances. Among the con- 

 glomerates shades of purplish grey and dark-purple are very common j 

 pinkish-grey is also common from the presence of large quantities of 

 pink felspar, derived from the decomposed granite-gneiss rocks ; whitish 

 grey where quartz pebbles abound, and light reddish-brown as a general 

 color, are also of very common occurrence. The shaley beds are mostly 

 without any very remarkable colors ; usually they are drab or pale ashy 

 grey.

The cherty breccia beds are peculiar features of the Kaladgi basin, 

 and help greatly, by their peculiar mode of weathering into disconnected 

 fragmentary masses with much small debris, to obscure the relations of 

 the under and overlying rocks. From their position and from their 

 relations to the great bands of very silicious limestone, highly charged 

 with bands and segregations of silica in the form of chert, which occur in 

 the southern part of the Kaladgi basin to the north and north-west of 

 Manoli, there seems good reason to regard the breccias as altered portions
