DUBRAJPUR GROUP. 49 



At two localities in the valley, near Saldiha and Bulaikandar, 



„„,,,, , there are traces of these upper beds existing as 

 Small detached out- rr & 



liers * thin patches, or outliers, which rest on the Damu- 



das. These patches are too small for representation on the map, but 

 are interesting as evidencing former extension. 



Northwards, the high ground between Asanbani and Gamhra* is 

 Sections north of the formed of pebbly grits and sandstones, the former 

 Brahmmi. often strongly resembling the upper Panchets or 



Mahadevas of typical localities. Beyond Gamhra the range, which 

 includes the trap-capped hills of Dubrajpiir and Churla, and the Paharea 

 village of Indra, and also the semi-detached Mohwagarhi hill, afford, 

 admirable sections of these rocks. 



On a preceding page I have given the thickness as seen in the 



Indra portion of the range. At Mohwagarhi the original height of the 



gneiss base appears to be the cause of the diminished thickness of the 



sandstones and conglomerates which are exposed 

 Sections at Mohwagarhi. . . : . 



in the section of that hill. Starting from the 



foot of the hill near Balidih, we have the following sequence in ascending 



order :— 



Gneiss from base ... ... ... 175' 



White sandstones, grits, shales and conglomerates ... 250' 



Trap ... ... ... ... 75' 



Chiefly laterite, but includes some trap and inter- 



trappean layers badly seenf ... ... 350' 



850' 



* Gamhra is two and half miles to the north-west of Asanbani. 



f Prom another section the suh-division of this portion would appear to be— 

 Trap ... ... ... ... ... 75' 



Intertrappean ... ... ... ... 40' 



Trap ... ... ... ... ... 35' 



Laterite ... ... ... ... 200' 



350'
