Presence of large pumice blocks on Tierra del Fuego and South Shetland islands shorelines, from 1962 South Sandwich Islands eruption

We report on the source of pumice found on beaches of Tierra del Fuego (Argentina) and the South Shetland Islands (Antarctica), north and south of the Drake Passage. Petrological studies, chemical analyses and experiments on this pumice indicate it is most likely from a 1962 submarine eruption in th...
