ALABAMA MICA DEPOSITS 87 



occurring near the western edge of the mica belt, in 

 more or less close proximity to the ferro-magnesium for- 

 mations, differs materially from the mica of the central 

 and eastern positions of the zone in respect to color, hard- 

 ness, flexibility, etc., as the specimens drawn will serve 

 to illustrate. 



A line drawn from the Delta mica mine (which is lo- 

 cated in the N. E. corner of the county), and having a 

 bearing S.45W., will be found to lie at all points about 

 centrally of the observed and developed mica occurrences 

 in Clay county as far south as the vicinity of Idaho, or im- 

 mediately north of the Quenelda graphite mines ; south of 

 which point no mica deposits of any apparent importance 

 or value have been as yet noted in the county, although 

 such may be found to exist. 



"M. & G" Mica Mine. The "M. & G." mica mine is 

 located in the S. W. % of the N. E. % of Section 15, 

 Township'19 S., Range 8 E. 



It lies on the summit of a ridge of N. E.-S.W. exten- 

 sion at an elevation of 1,100 feet, tidal datum. The de- 

 posit of pegmatite entered has a strike of N.40E. and is 

 traceable on the surface by visible outcrops at intervals 

 for a distance of nearly a mile. 



Original development by the M. & G. Mica Co., of Chi- 

 cago, 111., consisted of surface cross cuts and pits, extend- 

 ing over a mile along the strike, directed at the determi- 

 nation of the most favorable point of entry, which was 

 finally selected, and the mine opened up near the N. E. 

 corner of the above described lot. 



At this point two slopes were driven 100 ft. apart in 

 the pegmatite body, following its S. E. dip at a slope 

 angle of about 45. Two cross entries were driven, con- 

 necting the two slopes, the first at 75, and the lower con- 

 necting entry at 150 feet below the surface, or at the foot 

 of the slopes; one of which was driven lower for a 

 drainage sump. 



The last examination made of this mine was in 1914, 

 a few days only prior to its shutting down by reason of 

 litigation arising among the property owners, since which 

 time, and in consequence of which litigation, it has never 

 been actively reopened.
