Sketch Section across Nirgundi Sill. 



The succession of beds is as follows : — 



c. Breccia of chert or hornstone ; brown, red, and bluish grey. 

 U^. Limestone with cherty bands ; grey and reddish grey. 



b. Quartziie sandstones ; shades of brown. 



a. Conglomerates and pebble beds ; pink, brown, and grey. 

 Gneiss. 



Small patches of dark iron-clay, most probably of subaerial origin, 

 occur dotted about on all the different formations. The limestone bed 

 is hidden by debris along the line of section, but shows at some distance 

 on either side. Here, as at Sitamani and E-amapur, the included pebbles 

 are mainly quartz and felspar in a sandstone matrix. 



h. Bilgi Section. — The next section worthy of separate notice oc- 

 curs a little south-west of Bilgi (Beelgee) , twenty miles further west. 

 The succession of rocks is here normal and the beds seen are — 



c. Breccia bed ; jaspery. 



b. Quartzites ; drab and red, blue and grey, drab and pinkish. 



a. Grits and conglomerates.
