One-step synthesis of tenorite
(CuO) nano-particles from Cu<sub>4</sub>(SO<sub>4</sub>)(OH)<sub>6</sub> by direct thermal-decomposition method, Materials Letters, 65: 171-174.
However, Brandstatter and Niedermayr (1993, 1994) investigated the metallic inclusions noted earlier by others and found them to be native copper; inclusions of black tenorite
were also found in elbaite.
Associated minerals are: hematite, tenorite
, lammerite, urusovite, orthoclase and johillerite.
It was also recognized by Ratcliff (1973) in the Continental pit area, where it formerly occurred in small amounts in the walls of the small pits at the Butte-Duluth, Bullwhacker, and Sarsfield mines, together with chrysocolla, cuprite, azurite, malachite, and tenorite
Among them: tenorite
, "illite" and zinnwaldite (from basalt cavities in the Molana quarry), hyalophane (adularia-like crystals associated with barite), marokite and "axinite" (a group name; actually only two members of this group, manganaxinite and tinzenite, are reported from Val Graveglia).
Associated minerals are: ponomarevite, piypite, sylvite and lesser amounts of dolerophanite, euchiorine, tenorite
, hematite and two unknown As-bearing minerals.
Associated minerals are: chalcocyanite, dolerophanite, euchlorine, fedotovite, tenorite
, cuprian anglesite and gold.

Other minerals thus formed at Monte Somma/Vesuvius are tenorite
, boric acid, and compounds of sodium, copper and lead.
In old collections and museums it is possible to see specimens of azurite, malachite, cuprite, tenorite
, native copper and other typical species from Rio Tinto.
Associated minerals: fedotovite, tenorite
, langbeinite and lammerite.
