About VermiculiteHide

Formula:

Mg_0.7(Mg,Fe,Al)₆(Si,Al)₈O₂₀(OH)₄ · 8H₂O

Formula previously given as (Mg,Fe,Al)₃((Al,Si)₄O₁₀)(OH)₂.4H₂O.

As a Commodity:

Vermiculite

Colour:

Brown, bronze-yellow

Hardness:

1½ - 2

Crystal System:

Monoclinic

Member of:

Smectite Group

Name:

From Latin "vermiculor", breed of worms, in allusion to its peculiar exfoliation into worm-like aggregates on intense heating (for details see Krickl (2020)).

Type Locality:

ⓘ Millbury, Worcester County, Massachusetts, USA

Forms as an alteration product of biotite or phlogopite, by weathering or hydrothermal action. Vermiculite is mined as a natural insulation material.

The best exfoliation properties were observed not for pure vermiculite, but for intergrowths of vermiculite and other layer silicates (e.g. hydrobiotite).

Naturally expanded vermiculite can occur in volcanic rocks.
