380. Flett, J. S. On some brecciated stanniferous veinstones from Cornwall. 



Mem. Gcol. Suit. Great Britain, for 1902 (Mn)3), London, pp. I.i4-l.j!). 



Micro.scopic examination of tin-bearing veinstones from following mines: Dolcoath, 

 Wheal Basset, South Crofty, Cam Brea, Wheal Kitty and West Kitty. E.ssential 

 constituents of tliese tin ores are quartz, tourmaline, chlorite and cassiterite. 

 Fluorspar, pale micas, iron oxides, copper pyrites, kaolin (?) are present also, but 

 not universally, occasionally there are pieces of altered feldspar and fragments of 

 granite or slate.

Two mines are included in the East AVheal Lovell namely, Tregoneljris and Flat- 

 work. In this article the tin deposit and the peculiarities of the latter mine are 

 treated.

The tin-ore occurs as lenticular layers generally one or two inches thick, between 

 the planes of bedding of the killas. The layers appear to be the off-shoots from 

 north and south veins. 



385. . On the Great Flat Lode of Redruth and Camborne and some 



other tin deposits formed by the alteration of granite.

 Plan and section of tin mines on Great Flat Lode. 



Abstract: Rep. Brit. Ass. Adv. Sci., 1877, London, p. 71. 



It is worked for three and one-half miles, and consists of a leader or true fissure 

 vein only a few inches wide carrying tin and copper ores; a lode from 4 to 15 feet 

 wide on one or both sides of the leader, mostly of tourmaline rock, carrying 

 1 to 3 per cent of tin; a capel of only slightly stanniferous tourmaline rock 

 separates the lode from the slate or granite. There is an absence of wall or plane 

 of separation between the lode and capel or the capel and granite. Thinks the 

 lode and capel are altered granite, and that most of the lodes in Cornwall are 

 of similar origin. 



386. . On some tin stockworks in Cornwall.

 Abstract: Rep. Brit. Ass. Adv. Sci., 1877, London, p. 70. 



Stockworks occur in killas (slate), granite and elvan (granite porphyry dikes). 

 Gives a list of the stockworks occurring in each rock.
