• This paper is actually the starting point of a systematic interdisciplinary work (and the first of a series of papers) aimed to characterise amphibole fibers found in the building material used in Biancavilla, which has been extracted from the rocks were fluoro-edenite was found. The American Mineralogist is the journal with the highest impact factor in mineralogy, and this paper has been widely cited and also brought to new interdisciplinary and international collaborations concerning the study of asbestos.

• Fluoro-edenite, ideally NaCa2Mg5(Si7Al)O22F2, was found both as prismatic or acicular crystals of millimetric size and as fibers in the rock cavities in gray-red altered benmoreitic lavas occurring at Biancavilla (Etnean Volcanic Complex, Catania, Italy). It is associated with feldspars, quartz, clino- and orthopyroxene, fluoro-apatite, ilmenite, and hematite, and probably crystallized from late-stage hydrothermal fluids. Fluoro-edenite has been characterised by electron microprobe analysis, X-ray structure refinement and IR spectroscopy. Structure refinement allowed determination of cation site-preference and ordering. The discovery and characterisation of the new amphibole end-member fluoro-edenite is important for two main reasons. The first reason involves mineral systematics and nomenclature, and fluoro-edenite enlarges the compositional fields of a rather rare and still not well known amphibole subgroup. More important, it allowed to understand that the amphibole compositions which can crystallise as fibers are more than previously thought. The second reason, perhaps the more important for interdisciplinary researches and for human health, is that the occurrence of fluoroedenite at Biancavilla (Mt.Etna, Sicily) could be related to the anomalously high incidence of mesothelioma, a rare deadly pathology which is caused by environmental pollution and especially to the presence of asbestos.

Abstract

• Fluoro-edenite, ideally NaCa2Mg5(Si7Al)O22F2, was found both as prismatic or acicular crystals of millimetric size and as fibers in the rock cavities in gray-red altered benmoreitic lavas occurring at Biancavilla (Etnean Volcanic Complex, Catania, Italy). It is associated with feldspars, quartz, clino- and orthopyroxene, fluoro-apatite, ilmenite, and hematite, and probably crystallized from late-stage hydrothermal fluids. Fluoro-edenite has been characterised by electron microprobe analysis, X-ray structure refinement and IR spectroscopy. Structure refinement allowed determination of cation site-preference and ordering. The discovery and characterisation of the new amphibole end-member fluoro-edenite is important for two main reasons. The first reason involves mineral systematics and nomenclature, and fluoro-edenite enlarges the compositional fields of a rather rare and still not well known amphibole subgroup. More important, it allowed to understand that the amphibole compositions which can crystallise as fibers are more than previously thought. The second reason, perhaps the more important for interdisciplinary researches and for human health, is that the occurrence of fluoroedenite at Biancavilla (Mt.Etna, Sicily) could be related to the anomalously high incidence of mesothelioma, a rare deadly pathology which is caused by environmental pollution and especially to the presence of asbestos.
