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