10. Schist, micaceous.

 8. Schist, hsematitic, dirty looking. 

 7. Schist, argillo-micaceous, pale greenish-brown. 

 6. Conglomerate, quartzose pebbles in argillo-micaceous matrix. 

 5. Schists, argillo-micaceous. 

 4. Ditto, micaceous. 

 3. Schist, black haematitic, dirty. 

 2. Schist, with hornblendic bands. 

 1. Trap, contemporaneous, very thick, 



This series appears to represent only the south wall of the synclinal, 

 the beds at the eastern base of the section being slightly inverted to 

 the west. The eastern .wall of the synclinal is obscure and difficult 

 to make out because the haematite quartzites all die out in the ridge 

 north-north-west of Hargandona 1 (Hurgandody of sheet 58;, and the 

 merely schistose beds do not admit of identification and correlation. 



The range makes a great trend here from north- north-west to 

 west-north-west for a couple of miles, but then resumes its former 

 course to the north north-west. 



To north of the second bend the following succession of beds 



Section south of Budi- occurs, as tne ridge (which by this time has 



kanamaghat. greatly decreased in height and continues to 



decrease gradually northward) is crossed at a point about half a mile 



southward of the Budikanama ghat. The section runs east to west — 



7. Hornblendic schist, very shaley ( ? weathered ? ). 



6. Haematite quartzite. 



5. Hornblendic schist. 



4. Haematite quartzite. 



3. Hornblendic schist. 



2. Haematite quartzite, small bed. 



1. Trappoid, broad band. Prismatic jointing seen at intervals. 



Between the eastern end of the section and Kudatanni new tank 



Trap show west of ( not shown in sheet 58) lies a tract thickly 



Kudatanni. covered with great blocks of black trap. This 



I showed in the map as a great trap-dyke, but I am now inclined to 



think that it represents the surface of a great trapflow lying at the base 



1 A village with a similar name (Hurgoondona) is shown in sheet 58 about 2\ miles 

 to the north-east by north, but no such village exists, nor seem s ever to have existed 

 except in the imagination of the chartographer.
