A bstract A deposit of nonbentonitic clay has been found in the Goose Lake area of Illinois. The clay has unique properties and composition, and it is marketed under the trade name “Grundite.” Its chief constituent was first thought to be beidellite, but further detailed microscopic, X‐ray, and chemical studies have shown that it is composed of a distinctive mica‐clay mineral of the illite group. The clay possesses properties of plasticity, strength, and gel formation which have caused wide usage, in a variety of fields. The occurrence, constitution, and properties are discussed.
