MINERALS INDEX
Chalcopyrite |
| CuFeS2 |
| Tetragonal |
Chalcopyrite is found very rarely at Franklin, in granular masses and disseminated grains in the pegmatite and also intermixed with zinc-ore minerals, as in the Buckwheat open cut. A vein of massive chalcopyrite without any other mineral, in coarse limestone, is shown in a specimen in the Holden collection.
Farrington (54) described a 7-inch vein of chalcopyrite, galena, and sphalerite cutting white limestone very near the zinc-ore body that was uncovered during the early stripping operations on the southeast side of Sterling Hill. The mineral is not otherwise known from Sterling Hill.
