Alurgite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
K2(Mg,Al)4-5(Al,Si)8O20(OH)4
Colour:
Purple
A variety of Muscovite

Name introduced by Breithaupt in 1865 and characterized by Penfield in 1893 (vide Knurr and Bailey, 1986). Placed by W. T. Schaller (1950) as an intermediate between leucophyllite (now a synonym of aluminoceladonite) and muscovite. Study of Knurr and Bailey (1986) show that alurgite, treated as Mn-bearing muscovite-2M1, contains trivalent manganese (in contrast to "manganophyllite", with divalent Mn).
