hughes: kuehuebaei coal field. 15 



The north boundary is formed partially by a faulty whicli cuts the 

 beds transversely. The maximum throw is in the east ; the beds are very 

 much disturbed^ and dip at high angles. North of Bayra^ the fault 

 leaves the fields and is apparently coincident with the run of quartz 

 breccia which forms two to three little hills^ the largest of which is 

 about due south of Seelayah. 



The disturhance, which the Barakars have undergone^ although gen- 

 erally speaking slight^ has, in the close neighbourhood of the northern 

 fault, been considerable, and several of the dips are very high. 



The axis of a synclinal passes at a distance of 11 yards south of 

 the boundary, the beds north of it dipping to the south-west at 3£° and 

 upwards even to vertical, those to the south dipping to the north-west 

 at angles which rapidly decrease to 35°. 



An anticlinal occurs across the central part of the field, within 

 the "surhuds" Jogitand and Kuldiha, dying out in the direction of 

 Mahtadih and Purtdiha. 



The denudation of this antichnal ridge exposes, near Kuldiha, 

 almost the lowest beds of the group, and the bottom seams of coal crop 

 out in the Durdurwa. 



Of the further distribution of the group, the coarse sandstones and 

 grits are somewhat prominently developed in the Sooknid and Khakho 

 streams, and near Maheshlundih, they form a hiU south of the village, 

 which is very conspicuous owing to its being totally devoid of any 

 vegetation. 



Shales are more common towards the middle and southern portions 

 ol the field than in the north. 



The dykes which afiect the Barakars will be adverted to after the 



( 223 ) 



notice of the coal seams which I shall now give.
