Description
A dark gray copper oxide mineral with a metallic luster. Tenorite was named for G. Tenor, in Naples about 1860. While it can occur as an ore, tenorite has also been found as an alteration product of cuprite forming a thin dark layer over the red. The presence of tenorite as a patina may indicate the object was heated before or during burial (Scott 1997). In a basic environment of a burial site, tenorite has also been found as an alteration product of azurite (Gutscher et al 1989).
