84 ball: geology of aueunga and hutar coal fields. 



purple clays of typical Paucliet character, after which we pass again on 

 to yellow sandstone, of which numerous sections are afforded in the 

 streams near Bundodag-, where, owing to the vicinity of the fault, they 

 dip at angles of 50°, and even 70°. In the small area cut off by the fault, 

 bluish carbonaceous shales, as in the previous section, are associated with 

 the yellow beds, which appear to be generally conformable to the under- 

 lying Barakars, to which however they present the strongest contrast in 

 lithological characters. At the extreme end of this portion of the 

 field, where the two faults {vide map) intersect, these beds have been 

 squeezed into a V-shaped trough, on the southern side of which a portion 

 of the beds have been cut out by the east- west fault, as it is only on the 

 south side of the V that a seam of carbonaceous shale is seen, measuring 

 9' 6", dip 50°. There is undoubtedly a zone of Panchet beds round 

 the Sasung hill, but the sections are not very clear. 



We now pass to the section in the Bagh Digwa near Hoochloo. 



Overlying the Barakar section there, a series of 

 wesTof HooSo^'^"^^' steeply inclined sandstones apparently belong 



to this group. These are soon covered by coarse 

 oritty beds, which I should be inclined rather to refer to the Panchets, 

 but it is not clear how they can be so, as further west there are, at an 

 apparently higher horizon, calcareous sandstones of the well-known 

 Raniganj type. It is possible that some of the beds higher in the 

 sequence may mark a tongue of Panchets along the line of fault, but as 

 the plotting of the river is very defective, I have not attempted to indi- 

 cate this. On the other side of this fault there is a narrow strip of red 

 clays belonging to the Panchets, which are soon covered by Mahadevas. 



To the west of this, surrounding Jugguldugga, there is a patch of 



Panchets cut ofl' by the fault, which are themselves 



dugja!''"* ^^ J"g§«l- surrounded by a narrow marginal zone of Raniganjes. 



These are of typical character, and include calcareous 



bands in the section seen in a small stream south-east of the village. 



In the loop bend of the Aurunga south-west of the village there is a 



small section of rolling sandstones of this group which rest on the much
