44! BOKAIIO COAL-FIELD. 



BoJcaro Section, (could.) — West of the scam in ILe Bokaro which was 

 stated to dip at 11° to 17° a fault of small throw crosses the river, pursu- 

 ino' the general course north-north-west. Between it and Gosee three or 

 four seams crop to the surface. One of them is accompanied by trap. 

 The angle of dip in the largest seam is 35°, 



South of Gosee a seam injured by trap occurs. The village water 

 o-hat exposes a bed of carbonaceous shales on one side two feet six 

 inches thick. The beds dip north-north-east. There is east and west 

 flexuring accompanied by small faulting, which give the beds a complicat- 

 ed appearance. 



About quarter of a mile west of Gosee coal again occurs and the 



section in descending order is —

The seam is thrown again, and the fault heads in the same direction 



as before. 

 The river here bends and exposes beds higher in the series, and we 



get repeated the whole the strata from No. 10 to No 1. 



Above the sandstone No. 1 comes —

 ciated rocks are again seen.
