About BerzelianiteHide

08854280014946275137709.jpg
Jöns Jakob Berzelius
Formula:
Cu2-xSe (x ≈ 0.12)
Previously given as Cu2Se.
Colour:
Silver-White, shiny lead-grey; easily tarnishes iridescent blue-grey
Lustre:
Metallic
Hardness:
2
Specific Gravity:
6.71
Crystal System:
Isometric
Name:
Named in 1850 by James Dwight Dana in honor of Jöns Jakob Berzelius, Swedish chemist [August 20, 1779 Linköping, Sweden - August 7, 1848 Stockholm, Sweden]. Berzelius is the father of analytical chemistry, inventor of chemical symbol notation, and discoverer of selenium (Se), cerium (Ce), silicon (Si), thorium (Th), titanium (Ti), and zirconium (Zr), in addition to other elements that he gave to his students to work on.

The mineral berzeliite is also named after Berzelius.
Dimorph of:
Berzelianite-Umangite Group.

A recent study showed the existence of a complete solid-solution series between high digenite [cubic, high-temperature digenite] and berzelianite (Pirard & Hatert, 2008).

Compare 'UM1983-17-Se:CuPb'.

Mineral SymbolsHide

As of 2021 there are now IMA–CNMNC approved mineral symbols (abbreviations) for each mineral species, useful for tables and diagrams.

Please only use the official IMA–CNMNC symbol. Older variants are listed for historical use only.
