Corderoite is an extremely rare mercurysulfidechloride mineral with formula Hg3S2Cl2. It crystallizes in the isometric crystal system. It is soft, 1.5 to 2 on the Mohs scale, and varies in color from light gray to black and rarely pink or yellow. Look up Mercury in Wiktionary, the free dictionary // Mercury, or Mercurius, derives from the Roman god Mercury (mythology). ...

It was first described in 1974 for occurrences in the McDermitt Mercury mine in Humboldt County, Nevada.
Black spongy masses to 2 mm of finely intergrown corderoite with tiemannite are locally abundant at location 1 on the 5,400 bench, and are the most common mercury-bearing species currently identified from the mine.
The minerals occur as somewhat globular coatings on fragments of brecciated jasperoid rock in direct association with crystallized fluellite, leucophosphite, strengite-variscite and anatase.
