MINERALS INDEX
Graphite |
| C |
| Hexagonal-rhombohedral |
Graphite is abundant in the Franklin limestone, in cleavage scales and plates, at both Franklin and Sterling Hill, and in the iron ores in the limestone. At all the limestone quarries near Franklin is more or less abundant wherever metamorphism through invasion by pegmatite has been effective. It has been found occasionally in the immediate wall rocks of the zinc-ore bodies but not in either ore body.
In a unique specimen in the Canfield collection graphite forms spheroids about half an inch in diameter, with fibrous structure and mammillary surface. This is labeled from Franklin, but its exact source is not known.
