Description: Kildonan shore, south-east coast of Arran. Buteshire. A Tertiary sill ('Kildonan Castle Sill') intruded into Triassic sandstone. The foreground is the High Lateglacial Raised Beach platform. The 15 to 20 feet thick sill is a craignurite felsite, a typical 'grey basalt' generally with scattered slender porphyritic feldspars. The centre of the sill is flow-vesiculated, the elongate cavities are filled with 'green earth' minerals and calcite. The rock weathers with a thick greyish crust but is blue-grey when fresh. Green earth minerals are naturally occurring silicates used as the base for green dyes and pigments. Typical green earth minerals are glauconite and celadonite.
