AURUNGA FIELD : BARAKAR GROUP. 67

margin of field. quartz, a small inlier of gneiss being surrounded 



by these beds. Ironstone concretions, weathered out on the surface, are 

 here likewise very abundant. At Dunria the position of the bound- 

 ary is somewhat doubtful. Between Dunria and Renchee I saw no 

 sign of the carbonaceous zone. South of Renchee at the road-crossing, 

 we have on the east Barakar grits, and on the west soft sandy beds of 

 uncertain character, probably Raniganjes ; beyond them come in grits 

 which probably belong to the Panchets, but the position of the Rani- 

 ganj-Panchet boundary is here somewhat uncertain. 



In the neighbourhood of Rampur a series of streams afford a 



number of sections which throw much light on

the geology. South of the village there is a well- 

 marked faulted junction between the gneiss and some grits and shales 

 which dip north at 20.° In the bed of a tank the beds appear to be nearly 

 vertical. The fault strikes nearly due west from hence towards the 

 Jugguldugga hills, and with the aid of a north-west to south-east fault, 

 has cut a wedge-shaped area out of the field. The sole evidence of the 

 former existence of the Barakars is afforded by a small outlying patch at 

 Reharee which rests on the upheaved gneiss. 



In the Bagh-digwa stream north of Rampur the bottom bed is a 

 red arkose, upon which rest sandstone, grits and shales with dip of 35° 

 to south-west. Following this stream westwards Barakar, sandstones are 

 met with dipping in various directions. As the village of Hoochloo is 

 reached, a tolerably continuous section is exposed, carbonaceous shales with 

 portions slightly coaly dip south-west at 40°. Above these are sandstones 

 and a few thin bands of ironstones, the quality of which is probably equal 

 to that of the Raj bar ironstones. These are soon covered by rocks which 

 must be referred to the Raniganj group, and are thus separated from the 

 area of Barakars exposed to the south-east of Jugguldugga. We pass there- 

 fore again to the northern boundary, to describe the sections near Toobed, 

 before entering upon an account of the Barakars on the south of the field
