KuifKUK. The name commonly given in 

 India to a more or less compact, tufaceous 

 deposit of carbonate of lime with silica, 

 found in the soil, in drift-sands covering 

 other sands. This deposit, which is of compa- 

 ratively recent age, occurs in the form of very 

 irregularly shaped concretions, varying in size 

 from that of a pea, in some places, to that 

 of an egg in others, and bearing a resem- 

 blance sometimes to stalactites, and occa- 

 sionally assuming moss-like and. eccentric 

 shapes. 



The vast Kunkur deposits in the plains 

 and valleys of India are sometimes seventy 

 feet thick. Captain Newbold has brought 

 forward evidence to prove that they have 

 been produced from springs of water, the 

 remains of which may, in some cases, be de- 

 tected at the present 6.ay. It is also stated, 

 on the same authority, that the siliceous 

 deposits are apparently older than the cal- 

 careous, and that they were probably formed 

 when the waters of the supposed springs 

 had a somewhat higher temperature than is 

 the case now. 



All the lime of the Punjab is derived from 

 Eunkur.
