The main islands are Seil, Easdale, Luing, Shuna, Slate Islands, Shuna, Torsa and Belnahua. Scarba and Kerrera, which lie nearby, are not usually included. The underlying geology of the islands is Dalradian slate, which was quarried widely until the mid-20th century. Quarry working began in 1630 and at the turn of the 20th century, the quarries were yielding some eight million slates every year. The Garvellachs lie to the southwest. Definition Unlike some of Scotland's larger archipelagos such as Orkney and the Outer Hebrides, which are distant from other islands and also have their own Council area, local authority, the Slate Islands have no formal definition. The islands from which the slate that gives rise to the name was quarried on a substantial commercial basis are Easdale, Belnahua, Luing and Seil. The webs ...

Slate Islands (Ontario)

The Slate Islands are a group of four small uninhabited islands in Ketchikan Gateway Borough, Alaska, in the Inside Passage near the south end of the Alaska Panhandle, at the mouth of the Boca de Quadra, in Revillagigedo Channel (directly south of Revillagigedo Island), which connects to Dixon Entrance) and about a mile offshore of the Alaskan mainland. They are part of Misty Fjords National Monument. The nearest inhabited place, Metlakatla, is 21 miles distant. The largest island of the group is about long. The islands were named (as "Slate Islet" at the time) in 1793 by Captain George Vancouver, who described them as being entirely composed of slate Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism.

Slate Island
Slate Island is an uninhabited island of about (at high tide) in Hingham Bay, an arm of Boston Harbor. It is part of Boston Harbor Islands National and State Park and is just east of Grape Island (Massachusetts), Grape Island. The island mostly consists of slate outcrops partly covered with glacial till, and the shore is mostly rock. The highest elevation is . The island was visited seasonally by Native Americans. In colonial times slate was quarried from the islands (the remnants of the quarry are still visible), mostly for house foundations. William Torey was given a grant for the island in 1650, with a stipulation that anyone was free to extract slate. Slate mining continued to a small degree into the 20th century and contributed to soil erosion on the rocky island. Later owners included Joseph Andrews, Samuel Lovell, Thomas Jones, and Caleb Loring. In the 17th century the island became part of the town of Hull, Massachusetts, Hull (it is now in Weymouth, Massachusetts, Weym ...
