Description
Kernowite is a complex arsenate mineral with the composition Cu2Fe(AsO4(OH))4·4H2O.[2] 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.[3][4] 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.[3][5]
