Elias W. Rector
Formula:
(Na,Ca)Al4((Si,Al)8O20)(OH)4 · 2H2O
Colour:
White to light brown
Lustre:
Waxy, Greasy, Pearly, Earthy
Hardness:
0½ - 1
Specific Gravity:

Crystal System:
Monoclinic
Name:
Named in 1891 by Richard Newman Brackett and John Francis Williams in honor of Colonel Elias William Rector (11 June 1847(49), Little Rock, Arkansas, USA - 29 January 1917, Hot Spring, Arkansas, USA), a politician (Speaker of the Arkansas House of Representatives) and attorney in Hot Springs, Arkansas, who supported the formation of the Arkansas Geological Survey.
A 1:1 regular interstratification of muscovite/illite (dioctahedral mica) and montmorillonite (dioctahedral smectite). Frequently called "rectorite-K" to distinguish it from regularly interstratified paragonite/montmorillonite = "rectorite-Na".
