The graphite is crystalline, and much of it lamellar, occurring as fibrous 
crystals 2cm (three-quarter inch) long, or as masses of scales 1 cm 
(one-quarter inch) across, set at all angles to one another. In places 
the graphite has been slickensided. Along probable fractures in the 
graphite thin tabular bodies have apparently been recrystallized to 
fibrous graphite, the fibres, 2.5 em (one inch) long and 0.15 cm (one- 
sixteenth inch) in diameter, being arranged at right angles to their 
limiting walls. There is in the graphite much red garnet, (in crystals 
up to 5cm (two inches) in diameter) and irregular masses of blue cor- 
dierite and some yellow cyanite, white felspar and quartz, and small 
crystals of pyrite in part limonitized. Biotite occurs sporadically in 
0.3 em (one-eighth inch) plates, but is nowhere abundant.

The contact of the graphite lenses with the enclosing pegmatite 
is usually sharp, and “horses” of pegmatite are contained in them. 
Similar graphite occurs in normal pegmatite in the vicinity, and at 
one place a graphite lens appears to grade into graphite-bearing peg- 
matite. The form of the graphite masses and the nature of the associated 
minerals indicate that the graphite is merely a younger pegmatite 
which was deposited to a considerable extent at least in irregular fractures 
in the normal pegmatites. 
Much of the Long Island graphite is of excellent quality, the raw 
product probably carrying 75 % graphite and it could probably be 
hand-picked to a relatively high grade product. The known deposits are, 
however, scarcely large enough to be exploited.
