This paper describes thirty inorganic compound - secondary mineral phases- found in the nature for the first time. All compounds come from the Jáchymov ore district. All up-to-now available physical and chemical data and references to appropriate literature are given. Crystal structure of phase [ (MoO2)2As2O5(H2O)2].
