171 BROWN & HERON: GEOLOGY AND ORE DEPOSITS OF TAVOY. 



Another investigation of the tin-ore deposits in Lower Burma 

 was undertaken by J. J. A. Page of the Geological 

 Survey of India during the years 1907 to 1912. Full 

 reports of this geologist's work have not been published, 

 but abstracts of the first two seasons' results are avail- 

 able as follows : —

of India for 1907." Rec, Geol. Surv. Ind., Vol. XXXVII, 

 pp. 1—56. 



Cassiterite is said to be found under the following four 

 conditions : — 



(a) As a constituent of decomposed pegmatite rich in tourma- 

 line and muscovite. 



(6) In massive quartz segregations in and on the outskirts 

 of granitic hills. 



(c) In quartz veins and stringers in ground adjacent to 

 decomposing pegmatite. 



(/) Hill-side talus accumulations due to disintegration of 

 classes, (a), (b), and (e), extending to gravel deposits 

 along the stream valleys and in alluvial flats. 



Numerous examples of each of these kinds of deposits are 

 given.

 Gives localities in the Tavoy and Mergui districts where cassi- 

 terite and wolfram occur. Ground sluicing for tin-ore 

 was carried on during the monsoon season at the following 

 localities in Tavoy district : — 

 («) The Maungmeshaung river. 

 (6) Onhbinkwin. 

 (c) The Hindu river and its tributary streams including the
