Abstract

Fuller's earth from near Dry Branch, Georgia, is shown by X-ray analysis to contain comparable amounts of montmorillonite and cristobalite, and only minor amounts of other minerals. The cristobalite resembles the high form, but may be a very disordered low form. Electron micrographs show the montmorillonite to be lath-like, and the cristobalite globular in form.
