These results are for the concentrated sand, but in a number of 
cases they could have been concentrated to a higher degree of 
purity and thus contain a higher percentage of thoria. 
Geography 
Monazite is of wide spread occurrence in the United States, 
though commercial deposits have been found in but few r regions. 
The area in which monazite deposits of commercial value have 
been found in the Carolinas lies in the south central part of wes- 
tern North Carolina and in the extreme northw estern part of 
South Carolina. This area covers about 3,500 square miles and 
includes part or all of Alexander, Iredell, Caldw'ell, C'ataw r ba, 
Burke, McDowell, Gaston, Lincoln, Cleveland, Rutherford, and 
Polk counties in North Carolina; and Cherokee, Laurens, Spar- 
tanburg, Greenville, Pickens, Anderson, Oconee counties in South 
Carolina. The larger towns within or near the monazite region 
in North Carolina are Statesville, Hickory, and Shelby; and in 
South Carolina, Gaffney, Spartanburg, and Greenville. This 
monazite region is crossed by the Southern, the Seaboard Air 
Line, and the Carolina & North Western railroads. 
Several deposists of monazite have been located in northeastern 
Georgia, though their value has not yet been determined. One of 
these in Rabun County showed a good quantity of both gold and 
monazite in a preliminary test. In the adjoining Jackson County
