100 READER : REPORT ON THE RAMPUR COAL-FIELD. 



tracing the fault as shewn on the map, although in no instance is 

 any actual break of rocks observable. About a mile north of 

 Rampur on the left bank of the Eeb river the rocks are seen to be 

 twisted about in a very strange manner, and again about one mile 

 south-south-east of Rampur near a village called Tangadula, Talchir 

 shales can be seen within a small area dipping in many directions 

 and evidently indicating some disturbance. 



If the estimate I have given of the thickness of the lower 

 Barakar series be more or less correct, then from the map it will be 

 seen that a very fair idea as to the amount of throw of the fault can 

 be arrived at. Nevertheless it must be remembered that such 

 thicknesses are only estimated, and moreover that the broad band 

 marked as belonging to the first series of Barakars on the west (or 

 upthrow) side of the fault is so deficient in good sections that only 

 little weight can be given to this as a factor in arriving at the 

 displacement of the rocks. 



This zone, which comes next above the one just described, 

 extends up the Lillari to Dhoramuda, from 



Sandstone shale zone. 



whence its boundary sweeps eastward not far 

 to the north of Belpahar station. The hills north of Job belong to 

 this division, since the tesselated sandstone known to occur in its 

 lower half is observed near Job, dipping westward, and somewhere 

 between these hills and the Bilpahari Sitaram hills the divisional 

 line must occur, but the obscurity of physical relations renders 

 further discrimination almost impossible. It may, however, be added 

 that owing to the high dip and rising ground in the direction of the 

 dip, the width of the zone in the neighbourhood of Job is less than in 



the Lillari nala. 



The two upper zones being economically unimportant are not 



considered here. „ 



These rocks which overlie the Barakars consist at their base of 



brown weathering coarse-grained ferruginous 



Kamthis. sandstone. Since the conformity or otherwise 



of these beds with the Barakars is their only feature which is of use 



for the purposes of this report, their higher beds were not explored.
