Mg3(Si2O5)(OH)4
Colour:
green, brown, light yellow to white
Lustre:
Resinous, Waxy, Greasy
Hardness:
2½
Specific Gravity:
2.55

Trigonal
Member of:
Name:
Named in 1955 by Eric James William Whittaker and Jack Zussman for the type location which lies within the area of Cornwall known as the Lizard peninsula. The locality itself being at Eastern Cliff, Kennack, Ruan - Grade, Lizard Peninsula, Cornwall, England, UK.
Co-Type Localities:
Polymorph of:
Lizardite is volumetrically the most common serpentine subgroup species. It is typically a product of retrograde metamorphism, replacing olivine and orthopyroxene (enstatite) in ultramafic igneous rocks and some magnesian skarns.
Can contain nickel and form a Lizardite-Népouite Series.
Chrysotile and lizardite are lower temperature polymorphs, whereas antigorite is a higher temperature (>250°C) serpentine mineral.
Lizardite polytypes known: 1T (formerly called 1A), 6T1, 2H1, 2H2, 1M.
May be interstratified with saponite: UM2002-39-SiO:AlCaFeHMg.
It commonly contains some intermixed chrysotile, typically as asbestiform veins, forming a potential asbestos hazard when processing.

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.
