 color, classing as white in the commercial sheet. 



Elsewhere on the property, there is observable a deposit 

 of crystalline flake graphite, ' which is however as yet 

 undeveloped. 



Exhibit sample serial No. 120 is from this mine, at 

 the main opening in Section 22. 



CLEBURNE COUNTY. 



Cleburne County is comprised within three distinct phy- 

 siographic belts: the Appalachian Mountain, Piedmont 

 Plateau, and the alluvial area made up of the Tallapoosa 

 river bottoms. 



The mica belt or zone, which occupies the approximate 

 central part, runs N. E. to S. W. through the county, 

 lying altogether in the Appalachian. 



Topographically, it is principally a deeply eroded pla- 

 teau, containing many sharp and narrow, and some broad 

 ridges, having summit elevations of 1,000 to 1,500 feet 

 above sea level, its western boundary line being the 

 Tallapoosa river. 



In the southern part of the county, within the mica 

 bearing district, areas of the Appalachian Mountain belt 

 are outlying, comprising notably Turkey Heaven, Kemp, 

 .and Bald Mountains, and the vicinity of Chulafinnee. 



The underlying rocks are mainly mica and hydro-mica, 

 talcose, garnetiferous and hornblende schists, gneiss, and 

 quartzite conglomerates. The quartz occurs mainly in 

 veins, which are in many places gold bearing. 



Mica occurrences are in the pegmatites which are of 

 irregular formation in the gneiss and mica schists, with 

 frequent hornblende association, together with surface 

 float of highly crystalline, translucent, and transparent 

 quartz, in fragmentary form, cyanite, and ferro-magnes- 

 ium rocks. 



The Chulafinnee, and the Arbacooche localities, which 



were active and notable gold mining camps prior to the 



discovery of gold in California lie within the mica zone 



of Cleburne, as does also the Turkey Heaven Mountain 



;area which similarly carries numerous gold veins more
