About SenandoriteHide

00043710017271921091122.jpg
Andor Semsey
Formula:
AgPbSb3S6
Specific Gravity:
5.456 (Calculated)
Crystal System:
Orthorhombic
Name:
Donnay and Donnay (1954) summarize the complex early history of the andorite minerals. They introduced the name andorite VI to distinguish the species from (then) andorite IV (now called quatrandorite). The two species usually form together, forming polycrystals. The root name is in honor of Andor von Semsey (22 December 1833, Košice, Slovakia - 14 August 1923, Budapest, Hungary), mineral collector. The mineral semseyite was also named after him.

The name senandorite was proposed by Moëlo et al. (1984), who gives additional analytic history. It derives from the Latin senarius (= composed of 6 units) referring to the multiplicity of the basic subcell. The species was officially renamed to senandorite in 2022.
Formerly known as "andorite VI".
Often intimately intergrown with quatrandorite.

Closely related, unnamed AgPbBi3S6 is mentioned in Mineralia Slovaca 41 (2009) 183-190; it may be identical with gustavite.

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.
