phyllite, cutting across the bedding of the formation, while those 

 between this and the brecciated rock or schistose rock are paral- 

 lel with the strike. 



Besides the quartz as an impurity, portions of the deposit 

 are filled with small particles, some of which are chlorite, and 

 others hematite, giving them a decided speckled appearance. 

 These portions vary from seams a few inches in width to lenses 

 several feet thick. 



A cross section of these beds will probably not show an aver- 

 age of over twenty-five to thirty per cent of commercial pyro- 

 phyllite. 



The pyrophyllite rocks have a width of about 500 feet, but 

 not over 100 feet of this would constitute the workable deposits, 

 and of this but twenty-five per cent would be of commercial 

 pyrophyllite. This, however, is so located that not over fifty 

 feet would have to be mined to obtain the twenty-five feet of 

 good number-one material. 



While the talc deposits of Cherokee and Swain counties are 

 pockety in nature and of limited depth, the pyrophyllite forma- 

 tion is continuous and of considerable, though of unknown 

 depth. 



BARYTES 



This mineral, which is mined somewhat extensively in Vir- 

 ginia, North Carolina, South Carolina, Georgia, Tennessee and 

 Missouri is usually associated with limestone. There are, how- 

 ever, in T^orth Carolina and South Carolina deposits that are 

 interesting on account of a decidedly different occurrence. 



These barytes deposits that occur in a line running 1^. E. 

 and S. W. from Kings Creek, York County, South Carolina, to 

 the N^ortli Carolina line, and near Crowders Mountain, Gaston 

 County, N^orth Carolina, are very similar in their occurrence. 

 The barytes occurs in lenticular masses whose strike and dip 

 conform approximately to the strike and dip of the schistosity 

 of the schists in which they are found. The barytes very prob- 

 ably represents the filling of fissures and crevices in the schist 

 which may have been caused by the faulting and tearing apart 

 of the schist. These are lenticular in outline, pinching or nar-
