黝铜矿 Tetrahedrite

(重定向自Annivite)

黝铜矿是一种铜、锑的硫化物矿物,分子式为(Cu,Fe)12Sb4S13,通常与铜、银、铅和锌的矿物共生,虽然黝铜矿的主要成分是铜,但有的时候会被银、锌、汞、铁等物质置换,例如如银黝铜矿、黑黝铜矿(含汞)。银黝铜矿的银含量高达18%,所以有的时候黝铜矿也是一种很值钱的矿物。黝铜矿是1845年在德国的萨克森被鉴别出来。

. It is the antimony endmember of the continuous solid solution series with arsenic-bearing tennantite. Pure endmembers of the series are seldom if ever seen in nature. Of the two, the antimony rich phase is more common. Other elements also substitute in the structure, most notably iron and zinc, along with less common silver, mercury and lead. Bismuth also substitutes for the antimony site and bismuthian tetrahedrite or annivite is a recognized variety. The related, silver dominant, mineral species freibergite, although rare, is notable in that it can contain up to 18% silver.
