Luing

The larger part of the bedrock of Luing is provided by the Neoproterozoic age Easdale Slate Formation, a pyritic, graphitic pelite belonging to the Easdale Subgroup of the Dalradian Argyll Group. Thin bands of quartzite are also present. Zones of metamorphosed intrusive igneous rocks occur within the northeast of the island. Luing is cut by NE-SW aligned Siluro-Devonian felsite dykes and by numerous later NW-SE aligned basalt and microgabbro dykes which form a part of the ‘Mull Swarm’ which is of early Palaeogene age. Raised marine deposits of sand and gravel occur widely around the margins of the island, a legacy of late Quaternary changes in relative sea-level. ==Economy and culture==

A regular ferry service crosses the Cuan Sound which separates Luing from the neighbouring island of Seil, which is in turn connected by bridge to the mainland. They are a breed of red beef cattle, produced by the Cadzow family in 1947 from a cross between Beef Shorthorn and Highland cattle. ==Etymology==

According to Haswell-Smith (2004) the name "Luing" may derive from the Old Norse lyng, meaning "heather" or long meaning ship. However, Mac an Tàilleir (2003) states "this is probably a pre-Gaelic name of unclear meaning." ==History==

In the early part of the Christian era Luing would have formed part of the Gaelic kingdom of Dalriada. From the 9th to 13th centuries almost all of the Hebrides came under the control of Norse settlers and formed part of the Kingdom of the Isles. However, when Edgar of Scotland signed a treaty with Magnus Barefoot in 1098, formally acknowledged the existing situation by giving up Scottish claims to the Hebrides and Kintyre, Luing and Lismore were retained by the Scots. The graveyard at the ruined church of Kilchattan documents the lives of past islanders, with quarriers, sailors and crofters side by side. Gravestones of note include those of Covenanter Alexander Campbell. ==Footnotes==
