HUGHES : KUEHURBARI COAL FIELD. 13 



Throughout the Talchirs, there is no coal. This absence is one of 

 the specific characters of the series. Slightly 



No coal in Talchirs. • n i 



carbonaceous shales occur very occasionally^ but 



invariably where there is a passage into the overlying Barakars. 



No additions to the fossils from the Talchlr series have been obtained 



in this district. 



VI. — Damuda Series. 



Of the three groups («.) Ranigunj, (3.) Ironstone Shales, 

 (c.) Barakar, which compose the Damuda series,, it is only the lower 

 one — the Barakar — ^which is represented. In this respect, the Kurhurbari 

 resembles the coal fields of Deoghur or Kuraon, and ftkhuri, which 

 are nearly in the same latitude. 



Some fossil plants were procured by Mr. WiUson at Passarabhia 

 and Domahani, similar to those occurring in the Damuda rocks 

 elsewhere. 



Barahar ffroup.-^The Barakar group covers an area a little in 

 excess of 8 square miles, in which are contained aU the seams of coal 

 that have been mapped. A generaHsed section of the rocks gives the 

 same order of succession as in the Damuda coal fields. 



At base : — 



1. — Fine drab-colo\jred sandstones, not very unlike tlie tmderlying 

 Talchirs. 



2.— Light and dark-grey, pebbly beds, gi-its and sandstones. 



3. — Fine and coarse wMtisb-grey felspatbic sandstones, only pebbly 

 in places, occurring with beds of bituminous coal. 



4. — Coarse yellowish-brown and grey sandstones, with occasional 

 bands of grey shale. 



5. — Thick beds of carbonaceous shale and shaly coal, with thin 

 irregular beds of ferruginous shaly sandstones. These latter 

 rocks form the higher portions of the flat-topped hills.
