لیروکونیت
Sign in to saveLiroconite is a complex mineral: Hydrated copper aluminium arsenate hydroxide, with the formula Cu2Al[(OH)4|AsO4]·4(H2O). It is a vitreous monoclinic mineral, colored bright blue to green, often associated with malachite, azurite, olivenite, and clinoclase. It is quite soft, with a Mohs hardness of 2–2.5, and has a specific gravity of 2.9–3.0. thumb|left|Vugs in gossan lined with lustrous, blue-green liroconite blades and sparkly, dark blue [[clinoclase microcrystals from Wheal Gorland (size: 3.4 × 3.0 × 2.0 cm)]] It was first identified in 1825 in the tin and copper mines of Devon and Cornwal
