Vermiculite is a hydrated magnesium aluminum silicate mineral and is a Phyllosilicate. The formation of vermiculite has been variously ascribed to natural weathering, hydrothermal action, percolating ground waters or combinations of all these three actions. The basic structure of the mineral is identical to the micas and to talc: a 2:1 silicate sheet composed of two flat layers of silica and alumina tetrahedra (the tetrahedral layers), which are joined together in a layer composed of apical oxygen atoms, and magnesium, iron, and hydroxyl molecules (the octahedral layer).
