Thorny Cliff, Kennack Cove (Kennack Sands), Kennack, Grade-Ruan, Cornwall, England, UK

Locality type:Cliff
Classification
Species:'Asbestos' (not an IMA approved species)
Comments:Mountain leather forms thin, multilayered masses at the interface between some calcite veins and the bastite serpentinite host-rock.

It is characterised as a sepia-brown, lamellar sheet, friable and slightly flexible when dry and distinctly soft and flexible when wet. The margins of the sheets exhibit occasional fringes of separated asbestiform fibres.

Composition is almost certainly within the Tremolite-Actinolite series.

Colour:Sepia-brown, paling to greyish-white. Translucent to opaque. Becomes pale dun to white when fully dry.
