Small pieces of vermiculite

by Antonio Jordán, University of Seville, Sevilla, Spain

Vermiculite is a phyllosilicate, member of the Montmorillonite-Vermiculite group with two tetrahedral layers and an octahedral layer (2:1 layering). These minerals were found in Ojén Mountains (Málaga, southern Spain), a serpentinite-rich area.
