30° north of west. In the east^ several cross bands occur, which strike 

 due north and south to 10° and 20° east of north. In the south the 

 direction is from north-north-west to north-west. 



Granitoid Gneiss constitutes the hill of Khandauli, and forms a

Granite. In the above band, several coarse porphyritic granite veins 

 occur, whose general strike varies from north-east — south-west to east- 

 north-east — ^west-south-west. They invariably cut through the strike of 

 the gneiss, the edges of which are twisted and contorted along the veins. 



V. — Talchir Series. 

 The Talchirs, although poorly represented as compared to the great 

 body of Barakars, are exposed almost continuously along the different 

 boundaries. 



In the east of the field, the strata that crop to the surface are not 



always the most characteristic of the series. The finest development of 



them in this direction, is north-east of Mohli-

needle shales, the stamp rocks of the series, both 

 occur. The extreme eastern extension of these beds cannot be quite 

 accurately mapped, owing to the alluvium which commences to obscure 

 the structure of the ground in the vicinity of the Dandidih and Bhun- 

 daridih road. The Durdurwa nala flows entirely through Talchir rocks

sunk. No coal has been cut, and according to all 

 geological experience of the Talchirs, none will be found by sinking 

 lower than has already been done. The rocks that occur where the pit 

 has been made, are characteristic sandstones and shales of the series.
