HUGHES: KURHURBARI COAL FIELD. " 11 



The extension of the field towards its south-east corner is too much 

 obscured by soil to be accurately laid down. The contour of the ground 

 however would lead one to suspect the existence of Talchirs. 



Turning to the south boundary^ well marked silt shales of this 

 series occur in the flat near the Chunjka mines. A little tributary 

 that flows into the Suni exhibits them dipping at an angle of 30° 

 to the north-east. There is not much proof of a faulty and although, 

 from evidence along other portions of this boundary,, I am inclined to 

 think it is faulted^ it can only be so to a small extent ; the occurrence of 

 the Talchirs cropping to the surface and resting naturally on the 

 gneiss being direct proof against any view involving a considerable 

 amount of disturbance. 



Considered economically^, the absence of a large fault is to be regret- 

 ted ; fov, with a great throW;, there would have been a greater thickness 

 of coal-bearing rocks, whereas, now, the coal exposed near the 

 boundary appears to be the lowest that we can expect to find. 



Continuing westward, the Talchirs appear near Domahani ghat, 



and there is a small patch of them in the Khakho 

 Talchirs at Domahani. 



Nuddi, where the boundary of the coal field 



turns to the north-west. The angle of dip at this point is very high. 



From here to Sati ghat, the Barakars are in contact with the 

 crystallines, but north of the ghat, there is a fine display of Talchirs. 



The best ground for studying the series, however, is the Sooknid 

 river, and the stratigraphical succession is as follows : — 



At the base : — 

 Boulder conglomerate, the matrix of which is olive-green silt, and the boulders 



gneiss, schists, and quartzites. 

 Shales: bluish-grey, olive-green and brown, frequently nodular and occasionally 



calcareous. 

 Sandstones : thin-yellowish brown, shaly sandstones and true sandstones alternating 

 with shales.
