94 READER: REPORT ON THE RAMPUR COALFIELD. 



The Talchir-Barakar (Karharburi ?) boundary is fairly well- 

 defined in the Lillari nala where the fine-grained greenish grey 

 sandstones of the Talchirs are seen within a few yards of the coarse- 

 grained Barakar sandstones. At this point the Talchirs are striking 

 north-east and dipping 5° to the north-west as also are the overlying 

 Barakars. The next well-defined junction going east is at the 

 Rampur Ghat, on the left bank of the Eeb river, where the Talchir 

 rocks are seen within a short distance of the Barakars. Again a 

 quarter of a mile east of Rampur the Talchir sandstones are ob- 

 served at no very great distance from the Barakars. East-south-east 

 of the Rampur Ghat about ij miles Talchir shales can be seen 

 dipping in a very irregular manner, the main trend of which is north. 

 I saw no other decisive point to help in further defining this 

 boundary to the south. On the west, although not actually seen, it 

 is fairly certain that the boundary flanks the left bank of the Bonum 

 nala from the north of Malda to £ mile east of Khit where 

 it crosses the nala, sweeps round to the east of Jamwapali hill, 

 swinging round to the west again on the north side of the hill and 

 apparently striking the left bank of the Eeb river just south of 

 Jamwapali village. From this point the boundary would appear 

 to run practically north, striking the right bank of the Eeb river 

 about 5 mile north of the Gorgor confluence. 



There is a good exposure of Talchir sandstones on the left bank 

 of the Eeb opposite Gondgura. Previously a straight boundary line 

 from the east of Jamwapali hill up to this exposure and continued 

 up to the exposure north of the Gorgor has been drawn, but a sus- 

 picious looking ridge running along the curve I have defined, seems 

 to lend itself to a more natural delimitation. 



It will be observed that Talchirs are also shown on the Plan 

 faulted in to east of Gondgura. I shall treat on this exposure 

 later in the paper. 



So far then it will be seen that the Talchir rocks line the crystal- 

 line basin, and that in no instance do the Barakar rocks come in
