pebbles, angular fragments of red felspar of 



moderate size. In weathered masses the small " rice-grain " pebbles of 



quartz acquire a dull white color, and look not at all unlike lumps of 



boiled rice. These sandstones are not continuous round the scarped slope 



of the Sunkanur plateau, but appear at intervals. They follow the 



undulations of the gneiss surface. 



The sandstones on the plateau are regularly overlaid by fine 

 greenish sandstone and sandy flags, and slightly micaceous shales ; the 

 shales are merely local. A much better display of these sandstones and 

 shales is to be seen on the Kudapur Qubur (of map) or Lalapur hill already 

 Lalapur hill section. referred to. Here Mr. King found at the base a 

 thin series, one to three feet thick, of coarse, pebbly sandstones and grit, 

 full of little rounded pebbles of clear quartz and with felspathic fragments. 

 The cementing materials here also are occasionally of a green color. 



Over the grits come about 30 feet of dirty green and greenish- 

 brown fine shales and flags, the lowest beds being 

 Green shales, 



rather more compact and fine-grained with as- 

 sociated bands of more massive and concretionary rock. Then over 

 these come in gradually chocolate and red-purple shales with seams of 

 limestone, and higher-lying calcareous flags forming the summit of 

 the hill. There are about 80 feet of purple beds on the shales, and 



this would give 110 feet of dingy green and 

 Purple shales. 



purple shales before the true flags of the summit 



are reached. Excepting in the thinness of the basement sandstones, this 



section agrees closely with the sections of the corresponding beds in the 



northern and eastern flanks of the Tirth plateau to the south-east 



of Talikot, which sections may be fairly called the typical ones for the 



western part of the Bhima basin. 



Other sections, both southward and eastward, show these purple-red 

 shales apparently graduating upwards into a series of limestones, which
