d CHALCOPYRITE epitaxially coating PYRITE with QUARTZ, Julcani Mine, Angaraes Province, Huancavelica, Peru, 13 x 7 x 5 cm | |
Interesting cabinet sized specimen with a layer of epitaxially coated Pyrite with Chalcopyrite. Part of the specimen is then has a covering of Quartz crystals. Only a few of these came out. So was probably from one small pocket. |
