C4 BOKARO COAL-FIELD. 



too compact, and do not contain mica, which is ahnost an invaviahle 

 constituent of the sandstones of the lower Panch^t group. Resting 

 immediately upon these questionable beds are green micaceous shales. 

 From this point the rocks are undoubtedly Panchets ; and the sandstones 

 become less compact, more micaceous, and more decidedly green. 



There is one other section in which coal occurs, that of the river 



between Pindra and Toolbool. The unconformity 



of the Panchets and Raniganjs is more apparent 



here than in either of the two streams mentioned above, which flow 



into the Damoodah. 



Raniganj beds ar6 exposed west of Bussutpoor in the Chootooa. 



To the noi*th they are faulted against Talchirs and crystalline rocks. 



Some coal is seen' about 500 yards south of the boundary.

In the Tapin-Pindra nullah two seams occur, but I have only 

 thought it worth while indicating one. They are both nearly worthless 

 owing to their bad quality.

Raniganj group is of real value; and with the

exception of the seam m the Dhurdurwa, south 



of the Kodwa and Sarum road, and that in the Pindra and Toolbool 



nullah, the whole may be set down as useless, except for the very 



coarsest requirements.
