98 READER: REPORT ON THE RAMPUR COAL-FIELD. 



were conformably overlying the Talchirs, doubts would arise as to 

 whether these rocks belong to the lowest zone. 



Here then it will be seen to be a difficult matter to fix the boundary 

 between the lowest or sandstone conglomerate zone and the next 

 above or sandstone shale zone. For the purposes of this report, 

 however, the boundary may be assumed to cut the Lillari just 

 north of the Barakar hill midway between Durlipali and Kiraruma. 



Going further to the east the next most suitable place for 

 consideration of this boundary is between Kodopali and Bundia. 

 Opinion here can be based upon the Kodopali boring on the one side 

 and the assumed presence of Talchirs near Bundia in the Eeb on the 

 other. As regards the borehole, it appears to have been started 

 at about the same horizon as a shale bed supposed to be identifi- 

 able with the Durlipali seam. The borehole went down to 485 £ 

 feet and at 448 feet left the coal and shaly bed and entered 

 into fine sandstone. This sandstone is probably the bed immediately 

 overlying the conglomerates, and if such be the case marks the line 

 of division between the two series. Allowing 120 feet as the thick- 

 ness of the lowest series gives it a total of about 600 feet from the 

 top of the borehole to the Talchirs. It is evident then that at about 

 ^th of the distance from the Talchirs near Bundia to Kodopali boring 

 the line of division must occur. 



Following up the Eeb river from Rampur all the sections seen up 

 to Gondgura belong without doubt to the lowest zone. Half a mile 

 up the river from the Rampur Ghat, however, conglomerates are seen, 

 so that, for our purposes, we may take the line as running just south 

 of Telancachar. 



The next point where anything like certainty obtains is near the 

 railway bridge over the Lumchibahal nala where conglomerates are 

 again seen. At Chuakani, a little village { mile to the north of 

 Begmar and f west north-west of Job, the characteristic tesselated 

 ironstone previously mentioned is seen. From this it follows that 

 the boundary must run on the "crop " side (in this case eastward) of 

 this exposure, the tesselated ironstone belonging to the zone above.
