142 W. BLANFORD^ WESTERN INDIA. [PaRT II. 



In the valley east of the Fort hill, a greenstone-like trappean rock 



Rocks east of the Fort ^^ ^<^®^^- "^^'^ ^'^^^^^ ^^^'^^ ^^ frequently met with 

 in the Bijawurs about Bagh, is generally highly 

 cleaved; though the cleavage surfaces are rough. It sometimes much 

 resembles the more obscurely crystalline forms of hornblend rock which 

 occur in the metamorphics. This may be an interstratified trap, con- 

 temporaneous with the Bijawurs. 



Next comes some white vein quartz, which possibly marks a fault 

 or line of fracture. The hill east of the valley is composed of black and 

 purple clay slates, interstratified with occasional sandy beds, and with 

 bands of a rock resembling a conglomerate of quartz pebbles elongated 

 in the direction of the strike of the cleavage, but the apparent beds are, 

 really, nodular masses of quartz elongated in the cleavage strike, which, 

 are evidently the result of incipient lamination. The cleavage here 

 strikes north-30°-west vertical. Beyond tbe hill again there is another 

 "band of the cleaved greenstone. 



A few hundred yards further east is the road from Bagh to Tanda, 

 via Agur. Slates are well exposed in some small sections east of the 

 road, and bedding is here distinctly seen crossing the cleavage. The 

 latter is not quite steady, it here strikes about south-25°-east. Bedding 

 distinguished by bands of different colours is seen dipping south-east, 

 varying to south, at an angle of about 45°. It is somewhat contorted. 

 Slates for roofing purposes might be obtained here, though not of large 

 size. 



Nortb^east of the slates is a bed of breccia, with jasper of a bright 

 red colour. This rock is highly ferruginous, and much of it resembles 

 that quarried near Burwai for iron ore. 



The next band is a talcose quartzite, extremely foliated and meta- 

 morphosed, with large irregular masses of quartz in the foliation, giving 

 the weathered surface the appearance of pegmatite or of granitoid
