Alphabetical List Tree DiagramDetailed 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. References: |
| ⓘ 'Allanite Group' Formula: (A12+REE3+)(M13+M23+M32+)O[Si2O7][SiO4](OH) |
| ⓘ Ankerite Formula: Ca(Fe2+,Mg)(CO3)2 |
| ⓘ 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. References: |
| ⓘ Anthophyllite Formula: ◻{Mg2}{Mg5}(Si8O22)(OH)2 |
| ⓘ 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. References: |
| ⓘ '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. References: |

| ⓘ Native Copper Formula: Cu Habit: Granular. Possibly euhedral cuboctahedra. Colour: metallic copper red, black tarnish. Description: Minute grains (approx 0.5mm) on surface of calcite vein, enclosed by massive, powdery talc.
Presence is signalled by small amounts of localised copper stain in talc.
Only one occurrence found. References: |
| ⓘ Pyrite Formula: FeS2 Habit: Cubic; also irregular masses Description: Small groups of Pyrite crystals associated with some calcite veins, mostly altered to goethite or limonite. Crystals to 2mm. References: |

| ⓘ 'Serpentine Subgroup var. Bastite' Formula: D3[Si2O5](OH)4 D= Mg, Fe, Ni, Mn, Al, Zn Localities: Habit: Pseudomorphous after primary Pyroxene group minerals - probably after Enstatite at this locality. Colour: Yellowish-green to olive green; brown or bronze; may appear silvery against dark groundmass. Description: Shining flecks in the serpentinite groundmass define the Bastite Texture Serpentinites.

| ⓘ Talc Formula: Mg3Si4O10(OH)2 Localities: The Caerverracks, Kennack Cove (Kennack Sands), Kennack, Grade-Ruan, Cornwall, England, UK Kennack, Grade-Ruan, Cornwall, England, UK Kennack Cove (Kennack Sands), Kennack, Grade-Ruan, Cornwall, England, UK Eastern Cliff, Kennack Cove (Kennack Sands), Kennack, Grade-Ruan, Cornwall, England, UK Thorny Cliff, Kennack Cove (Kennack Sands), Kennack, Grade-Ruan, Cornwall, England, UK Habit: Radial, botyoidal. Also compact to earthy. Colour: White, pearly. Surfaces discoloured to yellowish when exposed to seawater. Description: Associated with saponite veins, many voids are filled with radiating masses of crystalline talc. Expansions in the veins occasionally yield an uneven, botryoidal crust of Talc covering an underlying layer of Saponite. |
| ⓘ Vesuvianite Formula: Ca19Fe3+Al4(Al6Mg2)(◻4)◻[Si2O7]4[(SiO4)10]O(OH)9 Colour: Lavender, Purple Description: Power et al. (1997) report purple vesuvianite as a constituent of rodingite inclusions in serpentinite.
A qualitative element overview by ICP-AES showed significant manganese among the trace impurities (Peter Haas). |
