TIN 



H 



Tin ore in the form of cassiterite has been found in Vir- 

 ginia, IsTorth Carolina, South Carolina and Texas. 



What may be called the Carolina tin belt extends from 

 Gaffney, Cherokee County, South Carolina, in a general north- 

 easterly direction across this county; the southeastern corner of 

 Cleveland County, N"'orth Carolina, and across Gaston and Lin- 

 coln counties, ISTorth Carolina. The tin deposits found in 

 Eockbridge County, Virginia, may be a continuation of the 

 Carolina tin belt across Catawba, Iredell, Yadkin and Surry 

 counties, ISTorth Carolina. The general direction of the rocks 

 carrying the tin ore is the same as that in Virginia, and the 

 continuation of this direction from the Carolina deposits would 

 approximately cross those j^laces in Rockbridge County, Virgin- 

 ia, where tin ore has been found. The same rocks that are 

 outcropping in Surry County, l^orth Carolina, are also in this 

 same line and have the same general direction. The principal 

 locality in South Carolina where tin ore has been found is 

 about one mile north of Gaffney on land which belonged to 

 Captain S. S. Ross. For a distance of 13 miles from a point 

 about a mile northeast of the Ross mine no tin minerals have 

 as yet been found. The next place in the belt where tin is 

 known to occur is a short distance northeast of Grover, ITorth 

 Carolina, a station on the Southern Railroad. From this 

 point tin ore has been found almost continuously for over 14 

 miles to within a few miles of Lincolnton. ISTo tin has thus far 

 been found in North Carolina northeast of the Lincolnton lo- 

 cality, nor in Virginia until the Rockbridge County deposits 

 are reached. 



The section of ISTorth Carolina and South Carolina in which 

 the tin belt occurs is close to the border of the large area of 

 Archean gneisses which extend over a large portion of the west-
