SUPERFICIAL DEPOSITS. 17 



junction between these rocks and those forming the Kanig-anj group 

 is perhaps more clearly indicative of unconformity, still the faults may 

 have been the cause of this also. 



A small outlier of Ironstone-shales occurs on the banks of the 



Damoodah about three miles south of Poonoo.

On the occasion of my visit, a colony of Aguriahs 



was temporarily established close by for the purpose of making iron. 

 Although coal, sufficiently good for the purpose was on~ the spot, and 

 could be obtained with much less labour than is required in the pre- 

 paration of charcoal, still they exclusively made use of the latter 

 description of fuel. 



Small pits are sunk into the shales north of Goburdaha, whence 

 ore is taken out by the Aguriahs of the village of Kutha. 



Section III. Eaniganj group.— Brief as have been our remarks . 

 upon the Ironstone-shales, there is still less to be said about the rocks 

 composing the Raniganj group. 



The beds are so disturbed by faults that it Is impossible to offer even 



„ . , an approximate estimate of their thickness. It is 



Thickness uncertain. 



probably much less than half the full thickness 

 seen in the Bokaro field. 



- Such rocks as are seen exhibit the usual lithological characters 

 of the upper Damiida group. 

 No coal seams are exposed. 



IV. — SUPEEFICIAL AND EECENT DEPOSITS. 



Extensive spreads of recent deposits such as are found in the 

 district of Maunbhoom are rare in this part of Hazareebagh. Small 

 patches of the following varieties have however been met with. 



1 Clay Alluvium* 



2 Sand. 



3 Conglomerate* 



4 Laterite. 



5 Kuukur,
