5G BOKARO COAL-FIELD. 



Moorpa nullah west of Moorpa. — In this stream coal occurs very 

 near the boundary, dipping nearly due north at an angle of 35°. On 

 o-oing down the nullah more seams are seen ; the direction of inclina- 

 tion turns to the west, and there is a decrease in the amount of dip 

 to 12". One seam has been worked. In parts of it, it is fair coal. 

 There is a good deal of iron however in it. A fault cuts it off at one end. 

 This fault is an unmistakeable one, as there is a difference in direction 

 of dip on each side of it, and it is indicated by a natural feature — 

 a fall in the level of the ground, which produces a water-fall. In the 

 Hoharoo the fault is again clearly visible, the ironstones being brought 

 up against Barakars. The fault heads north north-west. 



Another river flows east of Moorpa. I did not examine its section 

 minutely. Coal, however, occurs in it. 



HoJiaroo Section (contd.) — ^The Hoharoo for the greater portion of its 

 course flows through ironstones, but Barakars are visible at the Bunwar 

 o-hat. On one side they are faulted. In fact a series of faults exists here. 

 I have no hesitation in saying that those which I have indicated are 

 clearly established. Of all the faults in the field I cannot speak 

 so confidently. 



The dip of the ironstones east of the fault is south-south-east 60° to 



70°, whereas that of the Barakars is north-north-east by east 37°.

 ones coming plainly into view are thin-bedded fine grained sand- 

 stones, some of them are finely variegated. Calculated thickness about 160
