Description: | Drumadoon, south-west Arran. Buteshire. Sill of columnar quartz-porphyry, with a little sill of basalt and beds of Triassic sandstone and shale below. A raised beach is seen in the foreground. The sill is composite, consisting of a central mass of quartz-porphyry approaching 100 feet thick with a thin sheet of basalt at both top and bottom. The rock has a microcrystalline grey groundmass with phenocrysts of quartz (up to 6 mm. long) and feldspar up to 13 mm. long). |
