RANIGANJ COAL FIELD. 



[Chap. IY. § 4. 



Sirsol, but outside the fault running up the valley. The possibility of 

 tracing them, however, proves that no great fault intervenes between 

 that immediately West of Raniganj and Sirsol, and the quarries at 

 Jemeri. There is not the slightest indication of any East and West 

 fault in this patch of ground. 



The section continues therefore regularly to 

 Jemeri, where a fine seam of coal offers the 

 folio wins; section : —

If now we proceed to the comparison of this seam with the various 

 seams of Damulia, Raniganj, Mangalptir, Harisptir, and Babusol, we 

 shall see that in every one of these seams there is, 



a. A bed of carbonaceous shale, varying from 8 to 1 foot in thick- 

 ness. 



b. Good coal, 8 or 9 feet thick, in one instance (Damulia) with a 

 thin parting of ironstone. 



c. Shale parting from | inch to 3 inches.
