Liroconite

Liroconite

Liroconite is a complex mineral: Hydrated copper aluminium arsenate hydroxide, with the formula Cu2AlAsO4(OH)4·4H2O. 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.

It was first identified in 1825 in the tin and copper mines of Devon and Cornwall, England. Although it remains quite rare it has subsequently been identified in a variety of locations including France, Germany, Australia, New Jersey and California.

The type locality for Liroconite is Wheal Gorland in St Day, Cornwall in the United Kingdom. [ [http://www.mindat.org/min-2413.html Liroconite: Liroconite mineral information and data ] ]
