Abstract

A lamellar macroscopic Mg-vermiculite from Santa Olalla, Spain, which is accompanied by some talc and mica, shows a reversible expansion on glycolation due to the presence of layers with two different charges. The most probable origin of the vermiculite is by low-temperature hydrothermal transformation of phlogopite.
