HUGHES : DEOGHUR COAL FIELDS. 7 



The neighbourhood of the outliers has been the scene of extensive 

 trappean action, and throughout the whole country, as far as the 

 Rajmahal Hills, the occurrence of trap is one of the most marked 

 geological features. 



It will be clearly seen from what I have said, that there is little 

 prospect of finding in this area a supply of coal which might be made 

 available. And that in any summary of the coal resources of India, the 

 field must occupy a very subordinate position. 



B. The Sahajori Coal-field. — The next outlier, for which I would 

 propose the name of Sahajori Coal-field, from the village of Sahajori 

 where the chief mining operations have been carried on, occupies the 

 ground between the Adjai and the Kuchia Grhogur rivers. It possesses an 

 area of 11 square miles of which nearly 5 are covered by the Barakars. 



1. TalcUr series, — The boundaries of the Talchirs are throughout 

 nearly all natural. The most important fault is the one south of Nugra 

 which afiects the Barakar rocks. A small fault throws the boundary 

 north of Burbadih, and another cuts off the Talchirs south of Kunjona. 

 The whole of the rocks in this area are pretty well exposed, but the best 

 sections are those of the Nugra and Beliarpur rivers. 



3. Damuda series, Barakar grouj^. — The Barakars occupy but one 

 area in this field, and the total thickness of the group may be approxi- 

 mately stated as 400 feet. There is no promise of coal in the few and 

 imperfect sections which are visible in the rivers. In the stream south 

 of Sahajori, there are two outcrops of thin beds of shaly coal, that dip 

 at angles of 8° and 10° to the south-south-east. 



At the east end of the village of Sahajori occur the coal seams 

 into which Mr. Sandys sank a pit. Their outcrops are not exposed. At 

 the time of my visit the workings were nearly filled with water ; but I 

 was enabled to see the end of the upper seam at the side of the inclined
