Illite Properties And Occurrences Assignment Point

An illite is a group of closely related non-expanding clay minerals. It is a clay mineral of a group resembling micas, with a lattice structure which does not expand on absorption of water. It is a secondary mineral precipitate, and an example of a phyllosilicate, or layered alumino-silicate. Illite was first described for occurrences in the Maquoketa shale in Calhoun County, Illinois, US, in 1937.

Although Illite is an aluminum silicate, it is a non-swelling clay. Illite has the same range of use as the smectite clays. In fact, some believe that Illite performs better than the smectite clays when used internally, the consideration being that the particle size of illite is smaller than smectite particles.
