83 BALL : GEOLOGY OF AURUNGA AND HUTAR COAL FIELDS. 



traces of Talchirs were met in this area. The prospect of the seams of 

 carbonaceous shales being found to contain good coal is very slender. 

 This is the more to be regretted since ironstone of good quality is in 

 great abundance, and the crystalline limestone is close by. The area of 

 this ironstone field is about 4 square miles. 



The next outlier to be mentioned is found north of Masiatu, and 

 consists of claySj sandstones and conglomerates,

mile. These are perched on a very irregular 



pedestal of metamorphic rocks, the elevation of the lowest beds varying 



within 100 feet in different sections. This deposit offers no particular 



points for further notice. 



The third outlier is situated beyond the southern boundary of the 



field near Nowagarh. It occupies about 2 



Outlier north of ^.g j^ijeg in about half of which Talchir rocks

are found. These are only exposed on the west, being 



overlapped on all the other sides. The Barakar beds consist of sand- 

 stones and conglomerates similar in character to those of the adjoining 

 parts of the field. There are only traces of carbonaceous shales, and the 

 rocks o-enerally present no particular points of interest. 



The last outlier occurs just outside the boundary north of Toobed ; 

 the rocks are red shales, and occupy a very small area. 



Section 3. — Raniganj Group. 



There are few clear sections of these rocks exposed, and as they 



shew a departure from the normal lithological characters of the group 



in a comparative scarcity of calcareous bands, and a prevalence of soft 



yellow sandstones not unlike those occurring in the next succeeding 



Panchet o-roup, it has not always been easy to discriminate them.^ The 



boundaries which have been drawn therefore must be understood to be, 



to a great extent, arbitrary. 



a Some of these yellow heds particularly reminded me of the Panchet sandstones of 

 the Damuda section in the Eanigan j field at Deoli, where the reptilian fossils were found.
