Melting temperature and phase stability of iron under core-like conditions shed light on Earth's geodynamics
Iron is one of the main elements found in the Earth's inner core, which is characterized by extremely high temperatures and pressures. Determining how iron behaves in these extreme conditions could thus help to advance the ...
Nickel mining a serious concern for climate action, reveals study
Land clearing for nickel mines is causing a more severe threat to the climate than initially thought, a study led by a University of Queensland researcher has found.

Deep beneath California's Sierra Nevada, Earth's lithosphere may be peeling away
The processes that form continental crust from the denser basaltic rocks of the upper mantle may make the lower lithosphere denser than the underlying mantle. One theory holds that the lower lithosphere splits away and sinks ...
