Vermiculite

Vermiculite is found in fine, rare, and somewhat larger sheets, and in other clay minerals with particles <4 μm. It is formed by weathering or hydrothermal alteration of biotite or phlogopite. Vermiculite is an essential ingredient of soil and clay sediments. The mineral can be transformed, easily and quickly, into smectite in surface weathering.
