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

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.

Physical Properties of VermiculiteHide

Colour:

Brown, bronze-yellow

Hardness:

1½ - 2 on Mohs scale

Optical Data of VermiculiteHide

Type:

Biaxial (-)

RI values:

n_α = 1.525 - 1.561 n_β = 1.545 - 1.581 n_γ = 1.545 - 1.581

Max. Birefringence:

δ = 0.020
Based on recorded range of RI values above.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.

Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.

Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.

Thickness: 30 µm

Rotation:

Surface Relief:

Moderate

Dispersion:

weak
