Name:
Donnay and Donnay (1954) summarize the complex early history of the andorite minerals. They introduced the name andorite IV to distinguish the species from (then) andorite VI (now called senandorite. 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 quatrandorite was proposed by Moëlo et al. (1984), who gives additional analytic history. It derives from the Latin quater (= composed of 4 units) referring to the multiplicity of the basic subcell. The species was officially renamed to quatrandorite in 2022.
Previously called 'andorite IV'.
Often intimately intergrown with senandorite.
Compare also arsenquatrandorite.
Often intimately intergrown with senandorite.
Compare also arsenquatrandorite.
