AURUNGA HELD : BAEAKAR GROUP. 77 



So great is the difference in appearance in this part of the section, 

 that it is difficult to regard it as representing the same horizon as that 

 to which Nos. 1 and 2 belong. As No. 1 is not really the highest bed, 

 but only apparently so in consequence of the faulted junction with the 

 Mahadevas, it follows that we get higher beds to the dip. 



The section of these in the next reachj dip, 15°, to 30° west of north, 

 is, [ascending) — 



(a). Carbonaceous shales, with coaly layers . . . 30' C/' 



(b). Sandstone, parting 1' 6'' 



(c). Same as («) 18' 0" 



(d). White sandstones . 25' 0" 



The descending section is again resumed in the reach beyond the 

 junction with the Sukri stream : sandstones, N.-N.-W. at 60°. These 

 correspond to No. 10 of the Aurunga section on p. 73, so that the 

 modifying effects produced by interpolation receive further illustration 

 here by comparison of the beds in the two sections which have been 

 measured above that horizon.

field. It does not, I am sorry to say, give any better, indeed not even so 



good a promise, as did the Rajbar section, of including any valuable 



seams. 



The next area to be described is that which lies west of Jaloom or 



Zalim, and is traversed in part by the Gowa and Aurunga rivers. The 



section in the Gowa river is not very perfect ; there

are a number of seams of carbonaceous shales 



parted by sandstones -, some of these contain coaly layers, but none are 



clearly exposed. One fragment of loose coal 3 inches thick was bright and 



of excellent quality, but I failed to find the source. The dips of 



these seams average 10° to north, but in places they roll a good 



deal.
