M. in See also:area; and its highest point is 3340 ft . (See also:Monte Capanne) . It forms, like See also:Giglio and Monte Cristo, See also:part of a sunken See also:mountain range extending towards See also:Corsica and See also:Sardinia . The See also:oldest rocks of See also:Elba consist of schist and See also:serpentine which in the eastern part of the island are overlaid by beds containing See also:Silurian and Devonian fossils . The See also:Permian maybe represented, but the Trias is absent, and in See also:general the older Palaeozoic rocks are overlaid directly by the See also:Rhaetic and See also:Lias . The Liassic beds are often metamorphosed and the limestones contain See also:garnet and See also:wollastonite . The next See also:geological formation which is represented is the See also:Eocene, consisting of nummulitic See also:limestone, See also:sandstone and schist .

The celebrated See also:iron ore of Elba is of Tertiary See also:age and occurs indifferently in all the older rocks . The deposits are superficial, resulting from the opening out of See also:veins at the See also:surface, and consist chiefly of See also:haematite . These ores were worked by the ancients, but so inefficiently that their spoil-heaps can be smelted again with profit . This See also:process is now gone through on the island itself . The granite was also quarried by the See also:Romans, but is not now much worked . Parts of the island are fertile, and the cultivation of vines, and the See also:tunny and sardine See also:fishery, also give employment to a part of the See also:population . The See also:capital of the island is Portoferraiopop .

.
The other villages in the island are Campo nell' Elba, on the S. near the W. end, Marciana and Marciana Marina on the N. of the island near the W. extremity, See also:Porto Longone, on the E. coast, with picturesque See also:Spanish fortifications, constructed in 1602 by See also: In 1596 Porto Longone was taken by Philip III. of See also:Spain, and retained until 1709, when it was ceded to See also:Naples . In 1802 the island was given to See also:France by the See also:peace of See also:Amiens . On Napoleon's deposition, the island was ceded to him with full See also:sovereign rights, and he resided there from the 5th of May 1814 to the 26th of See also:February 1815 .
