(Phys.org) -- A team made up of a diverse group of researchers has found after studying the composition of several asteroids that most such planetesimals had an abundance of highly siderophile elements in their mantles suggesting, ...
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 ...
