32 BOKAIIO COAL-FIELD. 



12. Coal ... 



13.. Micaceous arenaceous shale 



14. Carbo-argillaccous shale ... ... ... 



15. Slightly felspathic siliceous sandstone 



16. Carbonaceous shale with parting of sandstone 



17. Sand in river 



18. Very fine grained variegated micaceous siliceous sandstone exhibiting 



false lamination ... 



19. Carbonaceous shale containing ironstone 



20. Sandstone 



21. Concretionary carbonaceous shale 



22. Sandstone and very finely laminated micaceo-arenaceous shale 



A portion of the beds are afterwards seen that compose No, 17, and 

 the section is— 



17a!, Carbonaceous shale having a splintery fracture 



175. Variegated micaceo-siliceous thin-bedded sandstones 



I7c. Yellow calcareous sandstone 



VJd. Thin-bedded sandstones and shales 



After sandstones No. 22, the next strata are all lower in the sec- 

 tion. A very interesting little piece of geology occurs north of Karo- 

 panee, a quartz breccia runs north of the village, and probably indicates 

 the continuation of the fault, which forms the boundary of the field 

 south of Burhoo. A small fault heading north -north-west cuts off the 

 patch of Barakars and Talchirs which is seen north of Karopanee. 



Coal near Karopanee. — East of Karopanee there are two seams which 

 dip at an angle of 28° south-south-east. 



A clear section is that of the little stream east of Dhunneeya. A 



seam occurs a short way north of the Bokaro, 

 Dhunneeya Nuddee. 



and at the same spot a dyke is seen running east 



and west. 



Fifty yards north of this seam (the intermediate beds are sandstones) 



we get another seam much impregnated by iron. The section is— • 



Ft. In.
