Livingstonite: Properties and Occurrences

Livingstonite is a mercury antimony sulfosalt mineral. It is a mineral HgSb4S7 consisting of a lead-gray mercury antimony sulfide resembling stibnite. It occurs in low-temperature hydrothermal veins associated with cinnabar, stibnite, sulfur, and gypsum.

It was first described in 1874 for an occurrence in Huitzuco de los Figueroa, Guerrero, Mexico. It was named to honor Scottish explorer of Africa, David Livingstone.

General Information

  • Category: Sulfosalt mineral
  • Formula: HgSb4S8

Properties

Livingstonite is a monoclinic-prismatic mineral containing antimony, mercury, and sulfur. It is a rare mineral that is found in low-temperature hydrothermal veins in localities in Mexico, Japan, Kyrgyzstan, and Spain among only a couple of other countries.
