29, HUGHES: DALTONGANJ COAL-FIELD. 
The geological survey undertook the examination of the coal- 
measures late in 1867, and again in the season of 1868-69. 
In addition to the remarks which are contained in the preceding ' 
pages, I have some to make upon areas of sedimentary rocks which 
occur at Sathbarwa, and around the village of Latiahar. 
1st.—Sathbarwa is a cháti on the Daltonganj and Ranchi road, 
and is about 15 miles from the former place. 
Talchirs crop out in the Maila nadî, and on the road: I saw no 
rocks belonging to a higher series. 
2nd.—Ldétiahar.—This village is another chati on the Ranchi road, 
and its name may be appropriated to distinguish the coal-field in which 
Latiahar occupies, roughly speaking, a central position. 
The development of the Panchéts is much in excess of the other 
series which occur, viz., the Talchir and Damáüdá. The Panchéts that 
1 saw were restricted to the upper division, (which in one of my former 
manuscript reports, I suggested, might be the equivalents of the 
Mahadévas), and the characters that distinguish them most are their 
ferruginous composition and the great prevalence of pebbles. 
In many places the Panchéts rest directly upon the Barákars. 
West of Látiahar the aspect of the rocks at the base of the section 
in the river is peculiar. They are really Barákar beds, but distinguished 
in a great measure by iron. The iron which further to the east segre- 
gated and formed separate bands, in this locality has become generally 
distributed through the rocks. This prevalence of iron gives to the series 
` a similarity of aspect, by which attempts at sub-dividing are defeated. 
There is little workable coal; many coaly shale beds crop out in the 
U'ránga near Zalim, and there are carbonaceous out-crops in the neigh- 
bourhood of Balú Nagar. 
Areas of Talchirs in the Hazdéribdgh District. —There are two areas 
on the Balámath and Chutro road, the larger of which occurs near 
Sindwari. 
18th September 1869.
