EEFEACTOBY CLAYS 



OF ROCK RUN,, CHEROKEE COUNTY. 



Associated with the bauxites at Eock Eun are a 

 number of clays, most of them of fine grained texture, 

 but some showing small quantities of grit, and which 

 vary in color from pure white to mottled ones, which 

 at times contain an appreciable percentage of sand. 

 Samples of these clays from six different locations 

 have been tested, they come from whajt are known as 

 the Dykes old Iron Ore Mine and the Dykes Bauxite 

 Mine, on the property of the Eock Eun Iron Mining 

 Co. in Cherokee county. 



No. 1. is on t'he north side of the iron mine reserva- 

 tion at tbe extreme western end; No. 2 and 3 are from 

 the same side of the pit, but at points 125 and 200 

 feet farther east respectively ; No. 4 is from the west- 

 ern end of the Bauxite pit and on the north side of 

 the entrance to it; No. 5 is on the north side of 

 the same pit and No. 6 at the eastern end of it. 



Nos. 1, 2, 3, each show a face 15 to 20 feet in height, 

 and are of probably greater thickness. No. 4 is look- 

 ed upon as a very low grade of bauxite.
