70 BALL : GEOLOGY OF AURUNGA AND HUTAR COAL FIELDS. 



oedsj which, it is needless to observe, have very much thinned out. Pass- 

 ing the loop bend occupied by metamorphic rocks, the next section of the 

 Barakars is in the vicinity of the mouth of the Katari, where there is a 

 seam, not very well seen, which is overlaid by sandstones and grits, and 

 these, within a short distance, by the yellow sandstones of the Raniganj 

 group. Under this seam are some red beds which, in one spot on the 

 south bank, rest on decomposed gneiss, and for a short distance the junc- 

 tions with the gneiss are very irregular, the sections of the bottom beds 

 on either bank of the river exhibiting striking contrasts. 



In the next reach, from south to north, the following section is met 

 with : — 



Section in loop lend of Sukri vwrth of ManjTiar, dip to south, and 10^ east 

 of south [descending). 



(1). White stales and grit with one 4-inch band of coal 



about centre 10' 0" 



(2). Seam — 



Does not appear to contain any good coal, but is much 



decomposed, dip 30° 15' 0" 



(3). Blue and white shales, 70' at 30° = . . . . 35' 0" 



(4). Seam — 



Consists of alternating thicknesses of concretionary- 

 shale and papery coal of from 2" to 8", the latter 

 about one-third of the whole thickness, 18" at 



30== 9' 0" 



(5). Mottled and concretionary shales, portions passing 



into grit, 17' at 30° = 8' 6" 



(6). Blue (carbonaceous), white and mottled pink, concre- 

 tionary shales, 83' at 17° = . 

 (7). Similar beds, more carbonaceous in places, 100' at 20°= 34' 

 There is a transverse slip in the above beds which does 

 not, however, affect the above measurement.
