WOLFRAM DEPOSITS IN OTHER PARTS OF BURMA AND INE3A. 261 



1916, 28,000 in 1917 and 35,000 in 1918. In 1917, China, which 

 had been an insignificant producer before that time, brought 1,500 

 tons into the market, rising in 1918 to over 10,000 tons, or more 

 than the whole world's output for any one year before 1915. 



As F. L. Hess has pointed out, the world's known large tungsten 

 fields are grouped in the great mountain masses which parallel 

 the shores of the Pacific Ocean and in 1918 fully 92 per cent, of the 

 world's tungsten came from the Pacific shores. Of the remainder 

 5 per cent, had its origin in Portugal and Spain, while the small 

 deposits of England, Germany, etc... produced less than 3 per cent, 

 of the total. 1 



WOLFRAM DEPOSITS IN OTHER PARTS OF BURMA. 



As is pointed out elsewhere, wolfram and cassiterite have been 

 found at intervals over a distance of 750 miles in Burma, always 

 iii direct association with the granite ranges which stretch from 

 the Shan States to the extreme south of the province. The occur- 

 rences of the Kyaukse, Yamethin, Karenni, Thaton, Amherst, 

 Tavoy and Mergui districts have already been described by us. 2 



WOLFRAM DEPOSITS IN OTHER PARTS OF INDIA PROPER. 



The occurrences of wolfram and cassiterite which have been 

 discovered in other parts of India outside Burma, are not of great 

 economic importance. L. L. Fermor 3 has described wolfram-bearing 

 quartz veins at Kalimati in the Singhbhum district of Bihar, from 

 which about 36 tons of wolfram were won in the years 1916-1918. 

 Some years ago, a series of small wolfram-bearing veins were dis- 

 covered at Agargaon in the Nagpur district of the Central Pro- 

 vinces, interbedded with mica schists and tourmaline schists of 

 Dharwar age, but the total amount of wolfram obtained from them 

 was only some 3 or 4 tons. 4 Over 100 tons of wolfram were produced 

 from the Degana mine in the Marwar State of Kajputana during 

 the years 1916-1918. The mineral occurs in quartz veins with 

 coarse mica, ilmenite and fluorite. The country rock is granite.
