DUBRAJPUR GROUP. 47 



Further north in the Dwarka river section, near Deocha, these rocks 

 are again partially seen ; but in the neighbourhood 

 of Doldolli and Kutpahari a series of beds is clearly- 

 exposed, and close to the former of these villages we find the following 

 section, descending . — 



1. Trap. 



2. Excessively ferruginous tesselated grits and sandstones. 



3. Yellowish flaggy shales. 



4. Conglomerates and sandstones. 

 Fault. 



Metamorphic rocks. 



There has been a considerable amount of well-marked faulting of 



these beds in this vicinity. This is the more 

 Fault. ■ . ■; 



remarkable^ as traces or similar action in the more 



northern part of the area are not met with. This disturbance may be 



very ancient, and is possibly connected with the fact that in this part 



of the hills alone do we find a case of beds of intertrappean age resting 



immediately on the older rocks, without the intervention of the usual 



basal trap flow. 



The conglomerates and sandstones in the above section (No. 4) sufii- 

 Kesemblance to Bard- ciently closely resemble Barakars to make it possible 

 kars ' that they should be referred to that group, and it 



may be that all along the faulted boundary which extends from hence 

 northwards to the Brahmini river, traces of Barakars do exist, but the 

 sections are too obscure to render separation possible, and, as will be seen 

 all the subtrappean sedimentary rocks from the Dwarka to Ramgurh are 

 coloured on the map as belonging to the Dubrajpur. 



That the whole of these beds could not be referred to the Barakars 



is amply manifest, as not only have we the lithological characters of a 



portion of them to guide us, but also the dis- 

 Fossils. ^ . . .
