28 BALL: GEOLOGY OP THE EAJMEHAL HILLS. 



Close by is the valley of the Brahmini, of the principal portion of 

 the rocks exposed in which the following is a section : — 



1 . Gritty boulder bed, portions greenish-grey, containing frag- 



ments of tbe adjoining metamorphic rocks, q. p. verti- 

 cal strike, N. S. ... ... ... 9'^ 



2. Grits with bands and runs of angular fragments of I °& 



quartz and other gneissose materials in an unrolled f 3 



condition, the felspar undecomposed, at first vertical, | ^ 



but falling to 35° E. ... ... ... 160U 



3. Grey earthy sandstones with alternations of felspathic 



and quartzose sandstones, dip 20° ... ... 45' 



Interval of about 45'. 



4. Similar to No. 3, with two bands of carbonaceous shale 12' 

 Stream. 



It is not quite clear where the section should be resumed, owing to 

 the broken connection and the horizontality of the beds. Starting again, 

 however, from the middle of the reach where some beds rest ou one 

 similar to No. 4, we have — 



5. Sandstone, dip 6° 



6. Blue shale 



7. Gritty sandstone ... 



8. Carbonaceous shale (concretionary) 



9. Sandstone with blue shales ... 



10. Carbonaceous shale 



11. Coarse gritty sandstone 



12. Ditto 



13. Ditto in thin beds 



14. Blue shale, carbonaceous towards top 



15. Grit 



16. Blue shales 



17. Grits 



18. Ditto with thin bands of blue shales 



19. Indistinctly seen grits and sandstones ... 



20. Ditto exposed 



21. Interval representing thickness of, say ... 



22. Carbonaceous shale 



23. Sandstone 



24. Carbonaceous shale
