Title: | Nuove specie Minerali al Monte Somma: V. l'Ekanite | Journal: | MICRO | Series/Report no.: | /11 (2013) | Issue Date: | 2013 | Keywords: | Ekanite sanidiniti Cava San Vito Monte Somma |
Subject Classification: | 04. Solid Earth::04.04. Geology::04.04.05. Mineralogy and petrology | Abstract: | Ekanite, Ca2ThSi8O20, was found for the first time at the Monte Somma in fragments of a sanidinic project in the early 90s at San Vito quarry (Ercolano, Naples, Italy) in three light green bipyramidal crystals (with a maximum size of about 0.3 mm) associated with sanidine, “amphibole”, anorthite and scarce “mica”. The identification was obtained with a preliminary SEM-EDS analysis and confirmed by determination of the parameters of the elementary cell (I422): a 7.462 (5), b 15.047 (11) Å. |
