Loch Bà is a freshwater loch, about 5 km long, in the centre of the Isle of Mull, in Scotland. It is drained by the River Bà, flowing into Loch na Keal, a sea loch on the west of Mull.[1]

Geography[edit]

The Loch Bà ring dike, found on the Isle of Mull in Scotland, serves as a classic example of a well formed ring dike.[2] This intrusive body forms an oval and its diameter can be measured at roughly 5.8 km by 8.5 km. The width of the dike varies throughout the profile, with a maximum width of approximately 300 meters. The composition varies from rhyolite to felsite, with phenocrysts of alkali feldspar and mafic minerals.[3]
