9S FOOTE : GEOLOGY OF THE BELLARY DISTRICT. 



6. Schists, very ferreous. 



5. Haematite quartzite. 



4. Schists, dark greenish and blackish, passing into clay-slate locally 



and including a bed of massive quartzite sandstone, manganiferous 



in various beds, often coarse. 

 3. Haematite quartzite. 

 2. Schists, dark and light green. 

 1. Quartzite much altered. 

 Granite gneiss. 



If you carry the section across the ridge and down its eastern slope, 

 Raman Drug, East- tne following succession of rocks is met with, 

 ern section. b u {. ^y no means clearly seen, owing to the great 



extent to which the hillside is covered by haematite debris, which 

 has rolled, or been washed down from above. The sequence is in 

 ascending order stratigraphically, but in descending order topogra- 

 phically : — 



9. Haematite quartzite. " Red cliff " scarp. 



10. Argillites. 1 



11. Trappoid, black, contemporaneous. 



12. Haematite quartzite, in first low ridge, shaley in parts. 



13. Trapflow, dark green. 



14. Argillite red, ferreous. 



15. Trapflow, pale green. 



16. Schists, green ? hornblendic ? 



17. Trapflow. 



18. Haematite quartzite and schists. 



19. Trapflow. 



The beds in the Raman Drug section, which can be identified with 

 others in the Narihalla section, are the following : The haematite bed 

 No. 3 of the Raman Drug section corresponds with No. 3 of the 

 latter section ; in both cases the lowest haematite of the respective 

 sections. The " Prospect Point" haematite bed No. 5 can from below 

 be easily traced by the eye along the flank of the ridge into the Obla- 

 gundi gorge, where it forms bed No. 7 of the Narihalla section. No. 9 

 the " Red Cliff " haematite bed of Raman Drug, continues southward 

 into No. 9 of the Oblagundi gorge and the " gorge bed " of the Narihalla 



1 The argillites (No. 10) show in great force in the upper slopes of the ridge. As 

 seen, they appear to be soft and shaly, almost litho-margic. No section was met in 

 which they are unweathered. They show many colours, generally purplish, ranging to 

 pink, but whitish beds and others of Naples yellow tint are also to be seen. They have 

 been quarried to furnish colourwash for houses,
