Ichnusaite
A variety of Minerals
What is Ichnusaite?
Ichnusaite is a very rarely found mineral. Ichnusaite is a natural compound of thorium and molybdenum with the formula Th(MoO4)2·3H2O. It was discovered in Su Seinargiu, Sarroch, Cagliari, Sardegna, Italy in 2013. This locality is also a place of discovery of the second natural thorium molybdate - nuragheite.
