Detailed Mineral List:

'Actinolite-Tremolite Series'
Habit: Ranges from massive to frequently fine, soft, asbestiform masses lying transverse to the vein, also coarse, tough sheaves and bundles parallel to the vein. Veins vary between sub-millimetre to 150mm or more. Fibres sub-millimetre to (prossibly) in excess of 100mm.
Colour: White, pale green, olive green, blackish green
Description: It is likely, from anecdotal evidence, that most of the material from this site will tend toward the Tremolite end of the series, although Actinolite has been reported.
Reference: Alysson Rowan Collection
Ankerite
Formula: Ca(Fe2+,Mg)(CO3)2
Reference: Golley, P., and Williams, R. (1995): Cornish Mineral Reference Manual. Endsleigh Publications (Truro), 104 pp.
Anorthite ?
Formula: Ca(Al2Si2O8)
Habit: Tabular, anhedral and space-filling. To about 10mm across.
Colour: Transparent, white.
Description: CONFIRMATION REQUIRED A single vein of brittle, transparent material comprising three layers: An inner layer of an indeterminate mineral (possibly also a Feldspar) sandwiched between thin layers (<1mm thickness) of clear, white plates of Anorthite which produce a display of specular reflections from the single perfect cleavage. In situ, this material appears as a series of brilliant, sparkling points within a shadowed vein within the Serpentinite.
Reference: Alysson Rowan Collection
Anthophyllite
Formula: ☐{Mg2}{Mg5}(Si8O22)(OH)2
Reference: Power, M.R., Shail, R.K., Alexander, A.C., and Scott, P.W. (1997): Proceedings of the Ussher Society 9, 188-194.
Antigorite
Formula: Mg3(Si2O5)(OH)4
Habit: Bladed, sub-parallel.
Colour: White. Pearly on broken surfaces.
Description: Found as small lenses of roughly parallel, bladed crystals associated with Mountain leather. The Antigorite lenses are uncommon at this location. Lenses to 2-3mm thick and 25mm in length. Crystals are generally aligned along the vein, and sub-parallel with the vein.
Reference: Alysson Rowan Collection Floyd, P.A., Exley, C.S. & Styles, M.T. (1993) Igneous Rocks of South-west England, Geological Conservation Review Series, No. 5, Chapman and Hall, London.

Proceedings of the Ussher Society 9, 188-194.
'Asbestos'
Habit: Fibrous, matted. Impalpable, microscopic.
Colour: Sepia-brown, paling to greyish-white. Translucent to opaque. Becomes pale dun to white when fully dry.
Description: 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.

Formula: Cu
Habit: Granular. Possibly euhedral cuboctahedra.
