Abstract

A Quaternary or Recent tuff or pumice has weathered to an allophanic soil reminiscent of some described by Sudo. The soil has interesting engineering properties. Electronmicrographs show the apparent coalescence of alophane ribbons into a thin platy mineral, probably an early form of hydrated halloysite. The formation of crystals by the coalescence of mosaic crystallites is discussed.
