73 BALL : GEOLOGY OP AURUNGA AND HUTAR COAL FIELDS. 



faulted junction is clearly seen in the streams south-west of Subano, 

 where the coarse grits are in contact with the greenish Panchet sand- 

 stones. The general form and position of these areas will be best 

 understood by reference to the map. 



Resuming description close to where the Barakars were described as 



being covered up by the higher groups near 

 Section in Ghugri. . . . & -t^ 



Hochloo, in the region lying to the south-east of 



Jugguldugga, the first section to be mentioned is that afforded by the 



Ghugri. In this river between Rukhunt and a point south of Sukri 



the rocks are, for the most part, concealed by alluvium, and the precise 



position of the boundaries is somewhat uncertain in consequence, but 



they cannot be very different from what is represented. South of 



Kurmahi the effects of the great north-west south-east fault are marked 



by the steep and abrupt tilting away from it of some sandstones, grits 



and shales which dip at angles of 50° to 70° to south and south-south 



west. 



A little to the west of north of Bhurla the river has cut a deep 

 gorge through massive sandstones and grits which 

 of Bhurla™^ ° ^^^^ ^^P ^^ north-cast and north-north-east at angles 

 of from 20° to 30°. A little farther on, north of 

 Nowatolah, the boundary strikes a loop bend tangentially, and a section 

 is disclosed shewing a massive pebbly grit resting with original contact 

 on the face of thin purple sandy gneiss. After this the river runs with 

 the line of junction of contorted gneiss with south-east dip, exposed 

 on the south bank, and sandstones dipping away on the north. 



Beyoiid this about seven bands of carbonaceous shales appear by 

 interpolation. They do not include any coal. Several very pretty 

 natural junctions which have been affected by lateral thrust are then 

 met with at intervals, but the detailed description of which would occupy 

 too much space here. It must suffice to allude to one only. This is 

 where the boundary crosses the Auruuga river north of its junction 

 with the Ghugri.
