Basaltic trap. 



BUILDING STONES. 



A considerable variety of rocks suitable for building purposes exists 

 in the Rajmehal hills. The basaltic trap, if care- 

 fully chosen, affords a most durable building 1 

 material, and was formerly used in temples, forts and other structures, 

 not only in the immediate vicinity of the hills, but it was also carried 

 to towns situated at a distance in the plains. 



Some of the intertrappean beds consist of flaggy rocks, which 



__ . , , mig-ht be applied to many useful purposes. Near 



Flaggy intertrappean ° L r J x x 



te ds. Burio, in the centre of the hills, one variety of 



intertrappeans has been used as a building stone (for bridges) by the 

 Public Works Department.
