CB04 – Fluorite with Jordanite-Geocronite and Arsenopyrite. Milpo Mine, Atacocha Mining District, Cerro De Pasco, Pasco Province, Pasco Department, Peru.
Aerial group of well formed octahedral crystals of Fluorite, translucent, bright and with a very nice strong green color. On a Sulphide matrix composed of Geocronite-Jordanite and with small elongated shiny crystals of Arsenopyrite. Due to the contrast with the Sulphides, generates very aesthetic pieces. The analyzes of the Sulphides of these new specimens from the Milpo mine (SEM-EDS and XRD) show a correlation between Geocronite-Jordanite, both are isostructural and forming series. Samples analyzed show that the composition moves in the intermediate zone of the series. Therefore, the correct thing would be to label these specimens as Geocronite-Jordanite. The condition of the specimen is very good.
Specimen size: 6 cm x 4 cm
