Chalcocite |
| Cu2S |
| Orthorhombic |
Chalcocite is very rare Franklin. It was first brought to the author’s attention in 1909 by Mr. McGovern, of Franklin, who sent a specimen for determination, showing a thin calcite vein containing granular sphalerite and galena, with a few imperfect crystals of chalcocite. Later in the same year was made the interesting discovery of massive chalcocite associated with silver and magnetite, described under silver. (See page 26.)
