Английская Википедия:Bilibinskite
Шаблон:Short description Шаблон:Infobox mineral Bilibinskite is an Au – Cu – Pb telluride. It is a rare mineral that was named after Soviet geologist Yuri Bilibin (1901–1952), who researched the geology of gold deposits during the time of the USSR.[1]
Properties
Bilibinskite is a metallic mineral with a color that ranges from opaque bronze-colored to light-brown or brownish-pink. It has a sub-metallic luster, a brown streak color and has no fission. Bilibinskite crystallizes in the cubic system. It has a high relative density of 14.27. The mineral has a hardness of 4.5 to 5 and it is not radioactive.
Occurrence
Bilibinskite is a very rare mineral that formed in the weathering zones of gold tellurides. The type locality is the Kamchatka Peninsula (Aginskoe gold deposit) in the Russian Far East, where the mineral was discovered in 1978.[1] It has also been found in hypogene ores of Kazakhstan, Xinjiang and Tuva.[2]
