The Islands of Islay, Jura, Colonsay, Tiree and Coll
The Hebridean islands of Islay, Jura and Colonsay are mainly composed of Neoproterozoic metasedimentary rocks of the Dalradian supergroup, whereas Tiree and Coll are underlain by Archaean rocks of the Lewisian Gneiss Complex. Most of the terrain is low-lying; only the three peaks of the Paps of Jura...

The Hebridean islands of Islay, Jura and Colonsay are mainly composed of Neoproterozoic metasedimentary rocks of the Dalradian supergroup, whereas Tiree and Coll are underlain by Archaean rocks of the Lewisian Gneiss Complex. Most of the terrain is low-lying; only the three peaks of the Paps of Jura exceed 600 m. Successive episodes of ice-sheet glaciation have produced areas of ice-moulded topography, and retreat of the last (Late Devensian) ice sheet was accompanied by the deposition of outwash deposits and moraines, including the longest medial moraine in Scotland.
