Illite: Mineral information, data and localities.

Named in 1937 by Ralph E. Grim, R. H. Bray, and W. F. Bradley for one of the co-type localities, in Illinois, USA. In the time period the mineral was named, the probable supposition was that the leaching of interlayer K was a consistent feature throughout the mineral's structure and that the

USGS OFR01-041: Illite Group Minerals

Illite is essentially a group name for non-expanding, clay-sized, dioctahedral, micaceous minerals. It is structurally similar to muscovite in that its basic unit is a layer composed of two inward-pointing silica tetragonal sheets with a central octahedral sheet. However,

Illite - an overview ScienceDirect Topics

The illite age analysis approach (IAA, Pevear, 1999) can theoretically also provide additional information by distinguishing between authigenic and detrital illite clay mineral phases. Pevear (1999) discussed the influence of detrital mineral phases on authigenic illite formation for sedimentary systems in detail.
