MINERAL RESOURCES OF ALABAMA. 



bama restricted to the area of the crystalline or metamorphic 

 rocks, embracing parts or all of Cleburne, Clay, Randolph, Lee, 

 Macon, Tallapoosa, Elmore, Coosa, and Chilton counties. The 

 kaolins are usually associated with veins of coarse grained 

 granites or pegmatites intersecting the other rocks of this re- 

 gion, the kaolin being derived from the feldspars of these gran- 

 itts. 



The northwestern part of Randolph and adjacent parts of 

 Cleburne and Clay counties may be considered the central area 

 of kaolin occurrence, though it is not wanting in the other parts 

 of the region mentioned. 



Up to the present time none of these deposits has been uti- 

 lized in a commercial way, but from some of the Randolph 

 county kaolin specimen sets of fine china ware were made and 

 exhibited at the Art Institute Fair in Philadelphia, December, 

 1900, where they were awarded a premium.
