OccurrenceTenorite occurs in the weathered or oxidized zone associated with deeper primary copper sulfide orebodies. Tenorite commonly occurs with chrysocolla and the copper carbonates, azurite and malachite. The dull grey-black color of tenorite contrasts sharply with the often intergrown blue chrysocolla. Cuprite, native copper and Fe–Mn oxides also occur in this environment.[1] In addition to the hydrothermal, tenorite also occurs as a volcanic sublimate from Vesuvius, Campania, and Etna, Sicily, Italy. As a sublimate it occurs with copper chlorides, alkali chlorides and cotunnite.[1] The Vesuvian sublimate occurrence was originally named melaconise or melaconite by F. S. Beudant in 1832.[4] Tenorite was named in 1841 after the Italian botanist Michele Tenore (1780–1861).[3] See also
