46 BOKARO COAL-l'IELD. 



A dyke occurs nearly due west of the Tcekadar's house; and at the 

 west corner of the river is a small seam. Between this point and the 

 village of Dhakasarum, considerable rolling in the beds occurs, and the 

 tortuous course of the stream brings us in succession upon dips, vary- 

 ing towards nearly every point of the compass. 



The middle Barakars are well exposed near Dhakasarum. 



The first good coal is seen 230 yards south of the large dyke. 

 There are three seams close to each other. The best in quality is the 

 highest of them, measuring three feet and four inches. 27 yards 

 horizontal across the strike of the beds brings us to a seam of one 

 foot (good in quality). It occurs north of a bend in the stream; 50 

 yards horizontal from this, and we reach another seam ; and then 4(j 

 yards further a seam injured by trap. The large dyke crosses a little 

 lower down. North of it there are two more instances met with in which 

 trap accompanies carbonaceous beds, and then a dyke heading east and 

 west, or slightly north of east. The continuation of this dyke is exposed 

 in the Bokaro ; then it passes inland, and again crosses the Bokaro, 

 and strikes south of Layeo. 



The beds north of the large dyke are carbonaceous shales with 

 ironstones, but they are cut off by a fault heading north-north-east, 

 which causes an upthrow of the Barakars, so that the latter appear. and 

 continue steadily to the junction of the Bugjobra and Bokaro. 



T'auU with trap. — This fault is accompanied by an intrusion of 

 trap, and is the only instance excepting the example, south of Teelaya 

 and west of Ooda, of such an occurrence in the whole of the field. 



In the Bokaroh there is evidence of another fault ; as in the strike 

 of the beds of this section, we have strata much lower in the series. 



West of Teelaya. — There are two nullahs, in which nearly the same 

 sections are exposed. A large seam occurs just before the streams Ml into
