Description
Lunda Wick The sea cliffs on the west side of Lunda Wick in south-west Unst are made up of rocks belonging to the Westing Group of the Valla Field Block. They contain spherical or lens-shaped ultrabasic bodies which show mineral zonation due to metamorphic differentiation. The mineral zones from the centre outwards are typically antigorite, talc, actinolite, chlorite and biotite, but one or more zones may be absent in any one body. The zoned bodies are developed most spectacularly at Gorsendi Geo where fine examples of actinolite and biotite zoning are present, especially in some of the more distorted bodies.
