TALCHEER COAL FIELD. 79 



But in the Ramghur Coal Field of the Upper Damoodah, the position 

 of which is somewhat nearer to Orissa, we find much greater similarity 

 of mineral character in the lower beds (all the strata being unfossili- 

 ferous no better ground of comparison can be expected), as Mr. Williams 

 erpressly mentions a boulder bed, the description and position of which 

 are precisely similar to those of the corresponding bed in the Talcheer 

 basin.* 



Mr. WOliams says: — " The lowest beds of this (Bohcaroh) field are to 

 " be seen in the bed of the Boodu Nullah, on the South side of the village 

 " of Jarbah ; they are thick conglomeritic accumulations from the 

 " crystalline rocks. These beds of conglomerate differ essentially from 

 " anything before seen associated with the carboniferous rocks, being 

 " composed of enorraous boulders of granite, some of which measure 

 « f^Qiii S to TlO feet in diameter : these are also intermixed with large 

 " boulders of white quartz, chlorite rock, hornblende, and mica schist. 

 "* * * These conglomerates alternate with (? underlie) greenish- 

 " grey beds of shales and thin beds of fine-grained sandstones, and have 

 " a developed thickness of 900 to 1,000 feet under the lowest known 

 " beds of coal." 



Again, speaking of the Ramghur Coal Field, he says : — The lowest 

 beds are well exposed " on the surface near the village of Poonoo, and are 

 " principally constituted of rounded boulders of white quartz, gneiss, 

 " and other members of the crystalline formation. This conglomerate 

 " is, in fact, perfectly identical with that great boulder conglomerate 

 " observed 20 miles to the Westward, near the village of Indrajarbah 

 " (Jarbah of preceding extract.) The boulder conglomerate has been 

 " observed to underlay the three Coal Fields posited in the zillah of 

 *■ Ramghur, and evidently appears to be the lowest member of the coal 

 " strata in India with which we are acquainted."
