|---|---|---|
| Species: | Asbestos var: Mountain Leather | |
| 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. | |
| Habit: | Fibrous, matted. Impalpable, microscopic. | |
| Colour: | Sepia-brown, paling to greyish-white. Translucent to opaque. Becomes pale dun to white when fully dry. | |
| Abundance at site: | Rare | |
| Special Storage/ Display Requirements: | Specimens should be treated as extremely harmful, dust arising from this material is easily absorbed into the lungs and is known to cause progressive lung disease. Should be handled only when wet and should be stored in a sealed container. | |
