LOWER TRANSITION ROCKS. 147 



To the east of Nemkal village, at the south-eastern extremity of 

 the synclinal the Dharwar rocks have been deposited, abutting 



mt „ against a steep southern slope of the very rug-

ged granitoid foundation. The following forma- 

 tions are exposed in this section : — 



21. Hornblendic schist and rock. 



20. Haematite quartzite, altered ? whitish drab colour, weathers dirty pink. 



19. Haematite quartzite, thick, haematite laminae much limonitized. 



18. Ditto schist. 



17. Quartz rock, granular. 



16. Hornblendic schist, dip 55 N. 



15. Ditto ditto, dip 45 to 50 N. 



14. Gneissoid schist. 



13. Micaceous gritty schist. 



12, Hornblendic schist. 



II. Gneissoid quartzite. 



10. Hornblendic schist. 



9. Micaceous gneiss, coarse. 



8. Hornblendic schist, thin. 



7. Quartz, intrusive ? 



6. Hornblendic schist, thin. 



5. Micaceous gneiss, coarse. 



4. Hornblendic gritty schist, thin. 



3. Gneiss with nests of greenish mica schist. 



2. Hornblendic micaceous schist, coarse, well bedded in parts. 



1. Gneiss, coarse, well bedded? archaic gneiss? 



The annexed diagram (Plate VI) gives an approximate representa- 

 tion of the section which shows various formations not commonly met 

 with in the Dharwar system, and such as were not met with to any 

 extent in the other parts of the Copper Mountain synclinal nor in the 

 Sandur or Mallapan gudda bands. All the gneissoid rocks in the 

 above section come under this category, but they differ yet more from 

 the typical granitoids, and they are, moreover, in such a situation 

 stratigraphically that they can only be reckoned part of the Dharwar 

 series, unless, indeed, they be regarded as part of a younger gneissic 

 system which lies conformably to the true Dharwars. The existence 

 of such a younger gneiss series is not as yet positively proven, but it 

 may yet have to be established when the subdivision of the crystal- 

 line rocks has been proceeded with further, as it assuredly will be on 

 closer examination by future observers.
