Investigation of the Arkansas bauxite deposits by the U. S. Geological Survey during the years 1942 to 1945 has brought out the fact that secondary kaolinization or silication of the bauxite is much more common than has been generally recognized. On the other hand no direct evidence was found of the development of bauxite from kaolin.
