ball-clay deposits are in sedimentary rocks of Cretaceous age and younger. Hydrothermal kaolin deposits, which include most halloy- site clays, are thought to have formed mainly in Cenozoic time, but the host rocks of some deposits are much older. Some residual de posits are related to the present land surface, and others are covered
