16 RAMGURII COAL-FIELD. 



In immediate conjunction with the southern fault, and about half 

 way between the temple at the Hazareebagh 

 road ghat and the old fort, there are two, possibly 

 three seams, but they are much crushed, and therefore, though contain- 

 ing fair coalj are of quite insignificant value. 



Two seams occur near the mouth of the Nyeesurraie nuddee, the 

 larger one is about 19 feet thick ; it may be identical with the one men- 

 tioned as occurring on the north boundary. In the bed of the last- 

 mentioned stream, there are two seams containing a small quantity of 

 coal, but they also are much contorted. 



Several small outliers of Bardkars occur close to the boundary of 



this field ; they are, however, of small size ; their

Section II. Iron-stone shale group. — Differing from the group 

 of Iron-stone and carbonaceous shales developed in the Raniganj field, 

 its representative here has very little of the carbonaceous element. It 

 consists exclusively of argillaceous shales and sandstones, with a few 

 poor runs of argillaceous carbonate of iron. 



The area occupied by these rocks does not exceed half a square mile. 



The only section of them occurs in the Damoo- 



dah. At the base the dip is 70° to S. 10° W., this

IS quite unconformable to that of the nearest seen 



Barakars (25° to S. S. W.) ; however, as the absolute junction is covered 

 up, and the vicinity of the faults may account for this apparent uncon- 

 formity, it cannot be regarded as a safe indication of the relations of 

 these groups. The alteration and fall in dip which accompanies the
