Talchirs; trappean. 
Lowest Talchirs, a form of trap. 
Here, the course of the stream is over dark green trappean rock (weathering into a 
mudstone) with dyke-like masses of compacter rock, 
occasionally laminated and bedded, which is soon seen to be 
of the Talchir series. True Talchir conglomerates and fine 
muds occur very shortly after this, especially throughout the course of the river beds, but 
Talchir “ boulder bed ” they are volcanic muds and ashes associated with 
a great boulder bed of irregular thickness. Higher up 
come fine dirty green-mud and sandy-mud shales, and then thick beds of fine pale greyish- 
green sands. The lowest rock seen within the neighbourhood of the river bed is of trappean 
matter, generally devoid of lamination, of a dark-green color, 
occasionally nearly black, weathering of a dark-brown or 
reddish-brown color, of a compact dull stony texture, weathering into a compact sand-stone. 
This, as well as some of the shales, is occasionally slightly vesicular, or finely tufaceous and 
containing small fragments of slate and shale. This lower deposit is in places somewhat 
conglomeratic, but I think the true conglomerate is higher in the series. Over this 
come a few thin laminated beds of the same style of rock, or as often an ‘ash-like’ 
mud-stone rock with large and isolated smoothed frag¬ 
ments of lime-stone, slate, quartzite, and occasionally 
gneiss and granite. Some of these fragments are very large, as from 4 to 6 feet by 2 and 
3 feet, and they are generally lying singly in the finest form of this ash mud. At other 
times there are the more frequent seams of pebbles and shingle, though these are not crowded 
together as in an ordinary pebble or shingle bank. 
Style of the “ boulder bed.” 
This appears to be the representative of the usual ‘boulder-bed’ in the Talchir series: 
only in this region the new feature of its having been at times derived from volcanic sources, 
is I think clearly evidenced. As to the occurrence of the smoothed boulders in the fine mud, 
one can hardly lay aside the idea so often advanced by my colleagues, but that these were worn 
Trappean and glacial. and de P osited V S laciaI f «<*s. Two large smoothed and 
rounded sub-angular masses of Vindhyan lime-stone cer¬ 
tainly seemed to me to bo scratched otherwise than as from the wear and tear of the river; 
but I had no means with me for heaving them out of their position to see if the uncovered 
sides were marked in the same way. It is fair to state that the few boulders of lime-stone 
(unscratched on their exposed surfaces) which I did displace, were not marked at all on 
their buried faces. An enthusiastic glacialist would certainly have seen in the Talchirs of 
this region, a deposit similar to that which is probably being laid down in the neighbour¬ 
hood of Iceland, for instance, in the present day, where deposits of an undoubtedly volcanic 
source will be found associated with the debris of an ice-rubbed country. 
The path crosses the river four times in a distance of about 3 miles, Talchirs being 
, ... „ traversed all the time; but near the fifth crossing grey 
Barakars with seams of coal. _ oca 
Barakar sandstones are met with on the slope of the 
valley descending again to the stream, and in the bed of the same there is a seam of thinly 
laminated shaly and stony coal of about 20 feet in thickness, dipping at 30° to 35° south¬ 
west by west. 
The outcrop of the coal is seen very strong in the river bed as one goes northwards, and 
after a few yards the dip becomes a little easier. The river 
then makes a little bend by which the coal runs in under 
the bank, but beyond the bend it shows again in the river very strong, still with the dip of 
30°—35° which, however, rapidly increases to 45° (if not really more beneath). It is about 
18 feet thick, close to a narrow gully of the river crossed by a baud of sandstones having a 
Scam in the river bed.
