N2 - © 2017 Springer-Verlag WienAlumovesuvianite (IMA 2016–014), ideally Ca19Al(Al,Mg)12Si18O69(OH)9, is a new vesuvianite-group member found in the rodingite zone at the contact of a gabbroid rock with host serpentinite in the abandoned Jeffrey mine, Asbestos, Estrie Region, Québec, Canada. It occurs as prismatic tetragonal crystals up to 4 × 4 × 6 mm3 in size encrusting walls of cavities in a granular diopside. Associated minerals are diopside, grossular and prehnite. Single crystals of alumovesuvianite are transparent colorless or light pink with a vitreous lustre. The dominant crystal forms are {100}, {110}, {210}, {111}, {101} and {001}. The Mohs hardness is 6.5. The specific gravitiy is Dmeas = 3.31(1) g/cm3 and Dcalc = 3.36 g/cm3, respectively. The mineral is optically uniaxial (−), ω = 1.725(2), ε = 1.722(2). The chemical composition, determined by SEM–WDS (wavelength-dispersive spectroscopy on a scanning electron microscope; all oxides except H2O) and TG (thermogravimety; H2O) analysis, is: SiO2 37.1 wt%,
