Earth science:  Hot stuff under southern Chile

Julie D. Morris1

The isotopes of the uranium decay series are a wonderful tool for exploring geological processes that have taken place on the Earth's surface and in its interior1. On page 566of this issue2, Sigmarsson and colleagues describe how they have taken advantage of these isotopes to 'image' the melting of a slab of oceanic plate being subducted along a stretch of southwestern South America.
