CHAPTER VIII. 
THE KURASIA COALFIELD. 
This, the second of the Korean coalfields in point of size, has 
an area of about 48 square miles according to Hughes, being some 
10 miles long from west to east and 6 broad from north 
to south. It is an outlier entirely surrounded by Talchirs, except 
along its northern margin, where it is covered by the southern 
edge of the dolerite sill described on page 156. As far as one can 
^. ascertain from traversing this field, it has an 
'''''' average horizontal dip, with very gentle 
rolling about axes aligned in various directions ; but there is pro- 
bably a very slight general dip towards the south or south-west 
of the order of some 290 feet in 8 miles, this dip being deduced 
from the difference between the elevations of the Kuar Jharia 
(No. 45) and the Chirra Pani (No. 21) exposures of horizon 4, on 
the assumption that the correlation is correct. 
Messrs. Hughes and Hira Lai were unable to devote more than 
a very short period to the survey of this field, 
Hifa'^uT" consequently discovered only 7 outcrops of 
coal (Mem. G. S. I., XXI, p. 203). One of these, 
of excellent quality (that given as 13'6" thick), is probably the 
outcrop listed as Bijaura Jharia (No. 7) in Appendix I. The second 
outcrop is 1| miles S. S. E. of Kurasia, apparently in a tributary 
of the Kudra Nala. It is 6| feet thick, and has an excellent 
analysis, but was not visited by me. The third outcrop, 8 feet 
thick, in the ' Gorgheta ' corresponds with my Gorghela Nala (No. 4) 
of the same thickness. Owing to their inferior character details of 
the other exposures are not given, but three of them lie towards 
the western end of the field and are important as proving the 
extension of coal in that direction. 
During my own visit I was able to examine only those out- 
crops lying within reach of the villages of Chirmiri and Kurasia, 
and even then I was compelled to omit some of the outcrops 
known to the villagers. In Appendix I, I have given details 
of all the outcrops examined (except No. 33, see page 205) 
and in Tables 8 and 10 (pages 199 and 203) are shown the 
^.iialysea of the samples taken.
