Kernowite
A variety of Minerals
What is Kernowite?
Kernowite is a complex arsenate mineral with the composition Cu2Fe(AsO4(OH))4·4H2O. It was first described in 2020, and is closely related to liroconite, containing iron in the place of aluminium, making it green rather than blue. Its name is derived from Kernow, the name of Cornwall in the Cornish language, after being discovered in a rock mined c.1800 in the Wheal Gorland mine, St Day, Cornwall.
