74 3UNIGANJ COAL FIELD. [CHAP. IV. § 3, 



A seam of very carbonaceous shale is seen in the Pasai, a little 

 North of the Grand Trunk Road. Beyond this, the stream, for a long 

 distance, exposes no section, and the next coal seen occurs a little 

 South of Pathapidhi. This is about 10 feet thick. On the same 

 horizon, and possibly in continuation of this seam, an out-crop of a bed, 

 about 8 feet thick, occurs North of Patlakuri, and extends to the 

 boundary near Bareghar. At no great distance beneath this, one 

 or two other seams of unknown thickness are seen, and just above the 

 top of the Talchir beds, a very thick seam, 30 feet altogether, but 

 very shaley in parts, crops out along the stream for nearly half a mile, 

 presenting a very peculiar appearance. This seam is again intersected 

 by the Pasai, at the extreme point to the "West, to which Lower 

 Damuda rocks reach. The base of the Lower Damuclas is not more than 

 30 or 40 feet below the last-mentioned seam of coal, and the lowest 

 rocks of that series consist, in this locality, of hard, grey sandstones and 

 shales, the white sandstones and conglomerates, which formed the base 

 from near Etiapura, Samdi, and the Barakar, having disappeared. Near 

 the Pasai there is unconformity between the Damudas and Talchirs. 



Many of the seams along the Pasai and Kudia streams are occasionally 

 worked by the inhabitants of the villages around, and small quantities 

 of coal obtained. But such desultory workings never result in more than 

 the digging out of a few hundred maunds from the banks of the streams. 



Chaptee IV., Section 3. — Ironstone Shales. 



So few sections of these rocks are seen, that any detailed description 



of them is impossible. They are, throughout, 

 Bad sections. , . . 



almost of the same mineral character, consisting 



of a very fine black carbonaceous shale, which breaks up into small
