Digenita
Sign in to saveAlso known as neodigenite
Digenite is a copper sulfide mineral with formula: Cu9S5. Digenite is a black to dark blue opaque mineral that crystallizes with a trigonal–hexagonal scalenohedral structure. In habit it is usually massive, but does often show pseudo-cubic forms. It has poor to indistinct cleavage and a brittle fracture. It has a Mohs hardness of 2.5 to 3 and a specific gravity of 5.6. It is found in copper sulfide deposits of both primary and supergene occurrences. It is typically associated with and often intergrown with chalcocite, covellite, djurleite, bornite, chalcopyrite and pyrite. The type locality is

La digenita es un sulfuro de cobre, mineral perteneciente a la clase de los sulfuros. Fue caracterizada como un mineral independiente por , que en 1844 le dio ese nombre, derivado del griego διγενηζ, digenus, de dos orígenes, ya que es muy semejante a la calcosina y a la covellina, que se confundían con ella. Los ejemplares procedían de un yacimiento de sulfuros de cobre en pizarras en Sangerhausen, Mansfeld-Südharz, Sajonia-Anhalt (Alemania), que se considera la localidad tipo.
