AURUNGA FIELD : BARAKAR GROUP. 69 



'11. Seam, 8' vertical, 110' at 15° E. = 36' 6" 



contains about |th of burnable coal, separated in 

 Nortb of / bands, none of wbich exceeds one foot in thickness. 



12. Blue and white shales, 150' at 8° = . . . 20' 10^' 



13. Eed and yellow shales resting naturally on . .4' 

 Gneiss, vertical, strike 35° north of east. 



Samples of the coal in Nos. 5 and 11 have yielded on assay but 

 poor results, the percentages of ash being respectively 34*6 and 25'6.* 



In the streams to the north of this section the beds are somewhat 

 better seen^ and the poor shaly character of the seams is more clearly 

 apparent than where they are sodden with water in the bed of the Sukri. 

 Here too I am forced to state my belief that there is not much prospect of 

 a really good quality of coal being found in sufficient quantity to be mined 

 with profit. Proceeding westwards along the bed of the Sukri, the section 

 passes abruptly from the above-mentioned gneissose 



of ToS!^ '''*''''' ^^^^ ^^^^^ ^^*o ^ ^^^I'O'^ 20^^ ^f intensely tilted ripple- 

 marked sandstones with carbonaceous shales, which 

 are seen tobe in vertical faulted contact with the gneiss in several junctions 

 exhibited in the small tributary streams. In the Sukri itself the ripple- 

 marked beds dip 55° to south and south-south-west, and are covered up im- 

 mediately by yellow sandstones and some blue, slightly carbonaceous shales 

 belonging to the Eaniganj group. Just beyond the village of Bandudag the 

 Barakars are completely cut out by a fault, but immediately reappear with 

 some Raniganjes in a cut-off patch, to the north of the fault, — vide map. 

 The section of this cut-off patch west of Bandudag is particularly 

 well seen in the Sukri, and exhibits a peculiarly interesting piece of 

 geological structure. Underlying the yellow Raniganj beds, there is in 

 the first section a very narrow belt of nearly vertical grits with red clays 

 in natural contact with the gneiss. These are, 

 of BaSdudr ^''^^ ^^^^'^ therefore, the bottom beds and represent, in this 

 particular spot, the whole thickness of Barakur
