1891 R. N. Brackett & J. F. Williams in Amer. Jrnl. Sci. 42 16 The second hydrous silicate of alumina..is found in the Blue Mountain mining district in Marble Township, Garland county [Arkansas]... We propose the name Rectorite for this..in honor of Hon. E. W. Rector, of Hot Springs, Ark., who originated and has so unceasingly supported..the bills providing for the Geological Survey of Arkansas.

1950 Amer. Mineralogist 35 590 The structural scheme of rectorite consists of contiguous pairs of pyrophyllite-like units separated by pairs of layers of water molecules. An equally apt description would be the alternation of one pyrophyllite unit with one vermiculite unit.

1970 Clays & Clay Minerals 18 239 The regular mixed-layer clay mineral rectorite seems to form as a result of the alteration of muscovite—paragonite during late stages of diagenesis.

2005 Arkansas Democrat-Gaz. (Little Rock) (Nexis) 5 Apr. Arkansas also has a 10th claybearing substance, rectorite, which involves a clay mineral (some kind of Smectite) interlayered with sheets of mica.
