About AlushtiteHide

Formula:
Na0.5(Al,Mg)6((Si,Al)8O18)(OH)12 · 5H2O
Name:
After the type locality near Alushta city.
A variety of Tosudite

A clay mineral with a 1:1 regular interstratification of di-trioctahedral Li-Mg chlorite Cookeite-Sudoite series (with Cookeite/Sudoite ratio close to 1:1) and dioctahedral Smectite.


Originally described in 1914 from Kuru-Uzen' village (now Solnechnogorsk) near Alushta city (now Crimea peninsula, Crimea Oblast', Ukraine).

Recognised as a variety of tosudite, therefore discredited as a valid species (Burke, 2006). The validity of the discreditation is discussed. Tosudite was "discovered" in an alushtite specimen (see arguments in f.ex. Pekov 1998).




Classification of AlushtiteHide

Discredited
Approval History:
Discredited by IMA in 2006 (IMA 06–C = tosudite, cf. Burke 2006)
