Small uninhabited island of volcanic origin, N of the island of Nisyros.
Practically the whole island is an industrial mining site for obsidian, pumice and perlite.
Yali (Gyali), a small crescent-shaped island between the N coast of Nisyros and the SW coast of Kos islands, consists of rhyolitic obsidian domes and pumice deposits. It lies within the inferred location of the large submarine caldera associated with the eruption of the voluminous Kos Plateau Tuff, about 160,000 years ago, which produced extensive ignimbrites that cover much of the western half of Kos island and which produced a caldera of uncertain dimensions but one that could extend from Kefalos Bay on the SW side of Kos to Nisyros. Yali is oriented NNE-SSW and contains two distinct segments connected by a narrow isthmus formed of modern reef sediments. The SW part of the island consists primarily of a layered pumice-fall unit about 200 m thick; the NE part contains rhyolitic obsidian lava flows of similar thickness. Pumice deposits overlie soils containing pottery and Neolithic obsidian artifacts (Keller, 1982), but radiometric tephra dates are all older than 30,000 years. (see pumice quarry for specific references)
