14 HUGHES : KURHURBARf COAL FIELD. 



The structure of the field is that of a basin^ and the distribution 

 of the Barakars is, on the whole, very simple, the strata, as a rule, dipping 

 away from the boundaries. The only complication is in the ground 

 adjacent to Mohlichuan, Passarabhia and Kuldiha. 



The seams of coal are tolerably continuous throughout the area : 

 and although they are spoken of and described anew in different places ; 

 and although they vary in thickness, their identity can be proved by the 

 horizon at which they occur. 



The boundaries are distinctly traceable everywhere except in the 

 south-east corner of the field, where the alluvium which obscures the 

 Talchirs, similarly conceals the extension of the Barakars. 



The east boundary is throughout a natural one ; the bottom grits 

 and fine drab -coloured sandstones resting upon the exposed Talchirs, 

 almost continuously from Mohlichuan to Buriadih, and then eventually 

 overlapping them. 



The south houndary is slightly faulted, the maximum throw not exceed- 

 ing 100 feet, even if so much, where the displacement is greatest between 

 the Sati and Domahani ghats. Barakars form the contact rock a-long 

 the whole of the southern limit of the field, except in the three spots at 

 which Talchirs have been described as outcropping. South of Kope, the 

 boundary runs in the bed of the Suni stream, then passing through 

 Buniadih and keeping north of Agdoni, strikes, roughly speaking, 

 parallel to the course of the Khakho stream. 



The west boundary is natural. It crosses the Dhobldih stream, west 

 of the K-amnuddi dyke, and skirting the northern face of Maheshlimdih 

 hill, strikes nearly due east, then turning sharply north in the vicinity 

 of Mahtadih, runs a short distance east of the junction of the Bayra 

 and Kumarsote streams, and passing west of the Bayra village, joins 

 the northern boundary.
