(Phys.org)—A trio of researchers with the University of Cambridge and the University of Strathclyde has found evidence of a giant, five-fingered Icelandic mantel plume. In their paper published in the journal Earth and ...
Earth's mantle is the thick layer of silicate rock between Earth's crust and its molten core, making up about 84% of our planet's volume. The mantle is predominantly solid but, on geologic time scales, it behaves as a viscous ...
