RM3008 Fehrite and devilline
Les Ferreres mine, Rocabruna, Camprodon, Girona, Catalunya, SpainFehrite is a recent new species found in Almeria (Spain). Some years ago (2012) we identified this species in the Les Ferreres mine (Camprodon) but unfortunatelly we didn't have enough sample to finish detrmination and structural studies. Recently we found some more samples and the characterization was carried out based on the results obtained from the application of various analytical techniques: SEM-EDS, Raman and X-ray diffraction. Les Ferreres mine is the second locality worldwide for the species. We will send all reports to the buyer.
In this Catalan mine, fehrite appears as elongated elongated tabular to fibrous crystals, with a delicate bluish-green tone, and fibrous terminations. Usually, it is accompanied by devilline (blue) and brochantite (green). It is the magnesium analogue of ktenasite.
Size: 2.3 x 1.1 x 1 cm.
