Core processes articles from across Nature Portfolio

Core processes describe the transfer of heat and material between the Earth’s solid inner core and molten outer core and the exchange of heat across the core-mantle boundary, as well as the convection in the outer core that generates the geomagnetic field.

    High pressures may have enabled ferric iron-rich silicate melts to coexist with iron metal near the base of magma oceans early in the history of large rocky planets like Earth. This suggests a relatively oxygen-rich atmosphere during the late stages of core formation on these planets.

    Seismic observations reveal that the Earth’s inner core oscillates with a period of approximately seven decades. The multidecadal periodicity coincides with that of several other geophysical observations, particularly the variations in the length of day and the Earth’s magnetic field, suggesting dynamic interactions between the major layers of the Earth.

    The coda correlation wavefield technique provides a powerful tool for surveying planetary interiors using only data from a single station. Its application to the SEIS seismometer on the InSight lander, which has been providing unique data on the interior of Mars since 2018, is a promising example of what it can bring to planetary seismology studies.

    Evaporative loss of sulfur from molten planetesimals can explain the sub-chondritic sulfur isotope composition of the bulk silicate mantle, suggesting an important role for planetesimal evaporation in establishing Earth’s volatile budget.
