Title: | Leonardsenite del Vesuvio (secondo ritrovamento mondiale) | Journal: | MICRO | Series/Report no.: | /11 (2013) | Publisher: | 3/2013 | Issue Date: | 2013 | Keywords: | Leonardsenite Vesuvius fumaroles fluorides Alessandro Malladra |
Subject Classification: | 04. Solid Earth::04.04. Geology::04.04.05. Mineralogy and petrology | Abstract: | As a part of the scientific agreement between the Dipartimento di Chimica - Università degli Studi di Milano and the Osservatorio Vesuviano (Napoli), the content of the bottles belonging to the historical collection of the Osservatorio, most of them collected before the 1944 eruption, was examined. The study allowed to identify several new phases, among which the recently described d’ansite-(Mn). In samples collected by A. Malladra in 1920, leonardsenite, MgAlF5(H2O)2, was identified. The mineral occurs as minute colorless prismatic crystals, wit maximum size of about 100 microns. The identification was obtained by single-crystal X-ray diffraction. The unit-cell data are: a 7.083(3); b 10.155(4); c 6.816(3) Å. This is the second discovery in the world. |
