A CONTEIBUTION TO THE GEOLOGY AND MINERALOGY OF 

 GRAVES MOUNTAIN, GEORGIA.* 



THOMAS L. AND J. WILBUR WATSON. 

 INTRODUCTION. 



To the mineralogist, Graves Mountain, Georgia, has long been knoT^-n 

 for the occurrence of an interesting association of rather uncommon min- 

 erals. Knowledge of the occurrence of the interesting group of minerals 

 at this locality was first made known in a published paper by Professor 

 Charles U. Shepard in 1859. Since the appearance of Professor Shepard's 

 paper in 1859 practically no work, based on field study of the mountain 

 proper, has been published, although the literature contains many refer- 

 ences to the description of mineral specimens from this locality. 



Very little is known of the geology of the immediate area within which 

 Graves Mountain is located. Mining for gold and copper three and one- 

 half miles north, and for gold ten miles south, of the mountain has been 

 engaged in at frequent intervals since the early 50's. Detailed field studies 

 have not extended beyond the limits of the mines and no maps of any 

 description have been attempted for this part of Georgia. Within recent 

 years several geologists have recorded the results of their studies of the 

 metal mines but the intervening area, more especially that of Graves Moun- 

 tain and the immediate vicinity, still remains for detailed study and map- 

 ping. 



The description of the geology of Graves Mountain briefly summarized 

 in this paper is based on several short visits to the area by the senior author 

 since 1900. The last visit was made in March 1911, when a collection of 

 the rocks and minerals was made for laboratory study. The chief object
