6 HUGHES : DEOGHUE COAL FIELDS. 



To the nortli of these seams and nearer the village of Khumurbad, 

 there is a thick bed of carbonaceous shale, but with nothing worthy of 

 the name of coal in it. The large dyke and also one of the micaceous 

 traps cut through it. 



In the larger area of Barakars, there are two small outcrops of 

 shale dipping to the south exposed on the left bank of the Bogroro in the 

 reach before it turns north to join the Jainti. 



About half a mile west of Chopkiari a small seam crops out 

 in the right bank of the Jainti dipping south-west. The quality of the 

 fuel it contains is somewhat better than that of the Bogroro seams. 



Indications of coaly shale, but nothing that may be termed coal, 

 occur near Kala Jherri and Buskupi. Coal is stated to have been met 

 with in sinking the foundations for the piers of the Railway bridge 

 over the Jainti. Possibly the bed seen near Kala Jherri was struck. 



ByTces. — The Talchirs are intruded into by dykes of trap, the 

 greater number of which strike in directions between west and north. 

 The trap belongs to the augitic and micaceous types, which ordinarily 

 occur in our coal measures and their accompanying rocks. Of the latter 

 type, there are only three representatives, all of which occur near 

 Khumurbad. The dykes of this class are always thin, and aifeet the 

 rocks through which they pass to a much greater extent, than the 

 augitic traps. A very distinctive feature is their being invariably 

 decomposed and the depth to which this change has taken place. 



The largest dyke in the field strikes north of Kalibad in the direction 

 of Busjora and Khumurbad, and crosses the Jainti river south of 

 Turkajori. There is no evidence to show what the relations are between 

 the micaceous and the augitic traps ; but there is little doubt that all the 

 dykes of the latter class, notwithstanding differences in direction of 

 strike, are of one age.
